Middesk | Full-time | SF / NYC | Hybrid | middesk.com

Middesk helps companies figure out who’s actually behind a business. Banks, fintechs, and platforms rely on us to get that answer fast and accurate before they issue a card, fund a merchant, or open an account.

We pull data from hundreds of government agencies, resolve it into a single view of a business, and serve it through an API. Business verification is becoming core infrastructure connecting businesses, banks, and governments, and that’s what we’re building. And our engineers build with AI every day. Earlier this year, agents helped us refactor our entire data pipeline.

Middesk is a Series B company backed by Sequoia and Accel, came out of YC, and was recently named to Forbes’ Fintech 50. We’re looking for folks who like getting close to customers and turning that context into product decisions.

Open roles:

Curiosity (https://curiosity.ai) | Forward Deployed Engineer, DevOps Architect | Toulouse, France | ONSITE | Full-time (CDI) | Visa support

Curiosity Studio builds internal apps and agents from a plain description, on a company's connected data and inside its permissions. It runs on premises or in a private cloud, with any LLM. We're bootstrapped, profitable and based in Munich. Our customers are large industrial and regulated companies, Airbus among them, and Studio has 30TB+ of data connected in production.

We are starting a team in Toulouse that works at customer sites, in French and English, along with the engineers who build Studio.

Forward Deployed Engineer: take a customer's problem from the first workshop to production. You decide with them what Studio should build, connect their systems, model the data as a graph, and oversee the C#/.NET connectors and services it needs. You also ship features and agents on top.

DevOps Architect: Own deployments in customer environments, from the first technical discussion to handover, on private clouds or data centers. Networking, IAM, Linux, Docker, monitoring, backups, upgrades, incidents. You also write code alongside the forward deployed engineers.

We're looking for hands-on builders who enjoy working directly with customers. Full-stack project experience preferred. Fluent French and English required.

Interviews: a 30 minute call, a technical conversation, then the founders.

Zed Industries | North America, South America, Europe REMOTE | https://zed.dev/ Zed is a company for developers, by developers. All 3 of our founders have spent years in the trenches writing software and still do it almost every single day. We've raised $42M to support our ultimate vision, a new way to collaborate on software, where conversations about code remain connected to the code itself, instead of being tied to aging snapshots or scattered across different tools. The first step was creating a high-quality editor to serve as the user interface. Now this new investment lets us expand to tackle the next phase of our plan. We're developing a new kind of operation-based version control (https://delta.dev/) that incrementally tracks the evolution of your code with edit-level granularity, and we're integrating it into Zed to make collaboration, both with agents and teammates, a first-class part of the coding experience.

Return | HYBRID | Chief Information Security Officer (CISO) | Full-time

Return (https://return.energy) is hiring a CISO. We build and operate industrial-size Battery Energy Storage Systems. This is critical energy infrastructure, and it needs one owner for security and compliance.

We operate in the Netherlands, Germany, Belgium, and Spain. You will make a measurable impact on the energy transition at country level. Return recently raised €300M to support its growth.

We employ more than 150 people. The technical team consists of 24 people. Our platform automates work in energy storage, monitoring, market optimization, sales, project management, procurement, construction, and customer service. It runs on EU cloud and on compute at the battery sites. We run the fleet from two operations centers in the Netherlands.

In our first four years we built the platforms and passed the important audits. Now we need one person to own the whole security picture. Today the work sits with the CTO, the platform team, and the Head of OT. That does not scale.

You report to the CTO and have direct access to the management board.

Mastra | Founding Sales (Founding AE) | US Remote | Full-time

Mastra is the open-source TypeScript framework for building AI agents (agents, workflows, memory, evals, tracing). From the team behind Gatsby, YC-backed, https://github.com/mastra-ai/mastra

Why: Four months ago Mastra was a very popular open-source agent framework with very little monetization. Then we launched our platform, and now we're closing a couple of deals a week. Pipeline is growing faster than one person can work it, so this is our second dedicated sales hire. You start day 1 with a warm pipe: most leads are already using the open-source framework.

What you'd sell: Platform (Studio, Server, infra to run/debug/observe agents in production, hosted or self-hosted for regulated orgs), Agent Builder (agents without code), and Concierge (embedded Mastra engineers working alongside customer teams). Full-cycle, mid-market: Series A–C, often with regulatory or infra constraints, sales cycles of a few weeks, talking to eng leaders.

You have: Closed full-cycle deals in dev tools, OSS, infra, or AI. Enough technical depth to come across as a smart PM with engineers: understand their use cases and scope a solution. Founder or founder mentality. Comfort with a product that ships something new every week.

Apply: { https://jobs.ashbyhq.com/Mastra/d5fe8d36-843a-4f9b-9d65-779e... } We get back to everyone.

Fredrin | GTM Engineer | REMOTE (US) | Full-time | $130k + equity | https://www.fredrin.com/careers/gtm-engineer?utm_source=hack...

Fredrin is the multiplayer software factory: one app where a team and its AI Workers build software together, and Workers running Claude Code or Codex, on the subscription you already pay for, plan, build, test and merge the work. We build Fredrin with Fredrin: over 1,500 PRs merged last month. Free to start on macOS, Windows and Linux.

As our GTM engineer you'll build the analytics, attribution and automation behind growth: which launch, post or creator actually brings people in, and the workflows that run the funnel without manual work. You'll work alongside our founding growth lead, who owns the channels and the story while you make sure every bet can be seen and measured. You can build in code, you care about clean data, and you'd rather automate a task than repeat it.

Apply at the link above, and tell us the one thing you'd instrument first for us in week one.

Odoo | Software Developer (Python / JavaScript) | Grand-Rosière (near Brussels), Belgium | Hybrid, 3 days/week in office | Full-time | €10k signing bonus

Pond AI | Head of Engineering (founding-level) | San Francisco | Onsite | Full-time | https://joinpond.ai

Most non-tech businesses know exactly which workflows they want AI agents to handle, but have no one to build, connect and run them. Pond delivers custom AI agents to these businesses through a network of 7k AI builders, with Pond as the platform and security layer over MCP.

We're backed by Tier-1 VCs and a co-inventor of GPT, and we're looking for a hands-on technical leader to own the platform end to end.

You'd be a great fit if you:

- Build full-stack and ship AI agents in production (TypeScript/Python, LLMs, tool use)

- Have worked on payments, agent coordination/MCP, or platform/marketplace products

- Have early-stage startup experience (founder, founding or early engineer) and like to grind

Email [email protected] with something you've built.

Voluntas | Remote | Full Time | Software Engineer

Voluntas is a trading firm written 100% in Rust. We run systematic strategies, currently specializing in prediction markets, looking to expand our systems more broadly.

We're looking for someone passionate about data collection, clean abstractions, and processing trillions of rows of data. We care about the quality of the code we write, and we prioritize time for our engineers to properly build their systems, instead of pressuring them to churn out AI generated code.

If you're interested, send an email to [email protected] with a little bit about yourself. We'll respond with a link to our engineering challenge (in Rust).

Mozilla | Sr. Staff Software Engineer, Browser (New Products) | REMOTE (US or Canada) | Full-time

Mozilla's New Products group is a small team building new things on top of browser engine technology. We're hiring a hands-on, senior IC to run experiments inside browser engine internals and find out which ideas actually hold up.

What you'd do: design and build experiments in engine subsystems (DOM, layout, accessibility, JS runtime, networking), prototype features that let programs interact with web pages reliably, and measure everything. That means repeatable benchmarks, profiling overhead, and writing up the experiments that didn't work too. You'll use AI tools heavily, but you'll verify what they produce by testing and measuring it.

You likely have: deep experience in at least one browser subsystem, strong C++ or Rust, comfort in a very large codebase, a solid grasp of how the web platform behaves, and a real interest in AI agents and their tooling. Contributions to Gecko, Servo, Blink or WebKit are a big plus.

Stream | Multiple Positions | Amsterdam (NL), Skopje (North Macedonia) | Boulder, CO (US) | Toronto (Canada)) | Remote possible | Full Time | Visa Sponsorship | https://getstream.io

Stream powers Chat, Video, AI Moderation, and Activity Feeds for billions of global end users across thousands of different apps.

We're constantly hiring backend engineers, but I wanted to take this opportunity to tout my own hire because I'm hoping you'll come work with me... I'm pavlov on HN, been here for nearly two decades, and working in realtime media for a good while longer. Now I run the Video team at Stream and I'm looking for a Staff Engineer. You'd report to me with a direct line to our CTO. Check out the details:

https://jobs.ashbyhq.com/stream/82b37457-3d54-4f7a-8a0e-ae52...

You'd own the media plane of Stream Video. It's a modern stack: SFU in Go, cascading to handle very large audiences, ingest and recording fleets, global multi-cloud edge. Video is fundamentally different from request-based services, which means this is not just a seat in Stream's shared infra team, but a genuine Staff role with its own roadmap defined by you. You can email me directly at [email protected], happy to connect and tell you more.

Full-time role, hybrid with 3 days a week in our Amsterdam office, or remote from anywhere in the EU. Visa sponsorship for the Netherlands.

Also hiring: Staff Software Engineer, Infrastructure (Amsterdam), Staff Software Engineer, Backend (Amsterdam), Senior Fullstack Engineer, Moderation (Toronto).

Paradromics | Embedded Software Engineer | Austin, TX or Oakland, CA | Onsite | Full-time

Paradromics is building a high bandwidth brain-machine interface for clinical use. The implant we built is restoring function to patients by streaming out neural data from specific brain regions in real time, which we convert to e.g. speech using machine learning. Check out our recent article in the NYT: https://archive.ph/C6CRb .

We're looking for help in further developing and hardening our embedded Linux components, which work in tandem with FPGAs and our custom ASICs to read out neural data. Some of the ongoing efforts are: HIL testing on real devices, integrating new sensor ASICs, maintaining our Yocto build system, exploratory work on prototypes, improving our clinical UX, and improving the core code that receives and massages data. The code is largely written in Rust with a little Typescript, (and bash, and bitbake recipes, etc).

You'll be expected to have experience constructing reliable and understandable software in Linux, and some level of experience in building and interacting with embedded hardware. Rust experience is ideal but not necessary. We're not looking for a specific number of YoE, but for motivated and hungry engineers who want to push the frontier of brain-machine interfaces.

To apply visit https://paradromicsinc.applytojob.com/apply/u5hXN4N9ID/Embed... or email your resume and a little about yourself to me, [email protected] . I'll be glad to hear from you!
