3ive | Senior/Staff Software Engineer | REMOTE (Europe) | Full-time | Python, TypeScript, React, AI Agents

We’re building Cursor for mechanical engineering.

Imagine an AI that doesn’t just answer questions about a mechanical design, but can actually understand CAD models, work with geometry, and help engineers create and modify real designs. That’s what we’re building.

It’s a hard engineering problem. We’re combining AI agents, CAD, computational geometry, and interactive software into a product engineers can rely on.

We’re a small but mighty team looking for an exceptional, hands-on Senior/Staff Engineer to help build it. Think founding engineer in terms of ownership.

You’ll help shape our agent and backend architecture, solve challenging problems across the stack, and establish the engineering foundations as we grow.

We’re looking for someone who’s built ambitious products, ideally at startups or scaleups, and has the technical depth to figure things out when there’s no obvious solution.

Ideally, you have experience with CAD, 3D geometry, or engineering software, alongside strong software engineering fundamentals. Experience building AI agents is a big plus.

Our stack is primarily Python, TypeScript, and React.

Hey folks! I'm Dylan, CTO at BuildQ, and we're building out our founding eng team. Today, a $200M solar project sits for weeks while someone reads thousands of PDFs before it can be financed.

We're remote, and the benefits are great (a startup with a 401k match!).

We're looking for a Founding Engineer to join 2 of us on the engineering team. You'll ship to production on your first day, and you'll help shape what the future of BuildQ looks like.

Stack: Rails, Python, React, TS, Postgres, AWS

Machine Age | COO — founder-level role | Full-time | UK time zone | Salary post-raise

Machine Age is building a network of businesses and robotics providers to supply real-world data for robot training.

We’re seeing strong interest, with multimillion-dollar opportunities in the pipeline. We’re looking for a COO to work alongside the founder and help turn that interest into delivery.

You’ll grow our network of businesses, bring new robotics providers on board, and build the operations needed to scale both sides. This is a hands-on role for someone who wants to roll up their sleeves, build relationships and get things done.

You’ll need to work UK hours. This is a full-time opportunity, with salary starting after we complete our raise. An interest in robotics is a bonus.

Email frank@machineage.ai with things you’ve done and how you’d approach building a network of businesses and robot suppliers.

NetBird | Berlin, Germany (or remote, CET overlap) | Full-time

https://netbird.io/careers NetBird is open source networking and access control WireGuard-based overlay networks with zero-config peer-to-peer connectivity. Now working with new use cases in access for AI agents. Open source, built in Europe, used by thousands of teams worldwide. We're a small and growing team going up against (and working with) the incumbents in network security. Post Series A with 10xd revenue since the raise.

- Senior/Staff Backend Engineer (Go!!) : the control plane: peer coordination, policy and access control, multi-tenancy, and keeping it all fast as customer networks grow into the hundreds of thousands of peers.

- Networking/Client Software Engineer (Go!!) — Software Engineering on the NetBird client side: WireGuard, NAT traversal and hole punching, relays, DNS, and shipping one client across Linux, macOS, Windows. If you enjoy debugging why one connection out of a thousand won't go peer-to-peer, this is the role.

- Technical Product Owner: Turn feedback into a clear roadmap, and work closely with the team to ship it. You should be comfortable with networking concepts and enjoy talking to users as much as reading a spec.

- Technical Support Engineer: Help customers set up and debug NetBird in real environments (WireGuard, Linux, cloud, Kubernetes) and pass what you learn back to engineering. (REMOTE - US/EST hours)

We have an office in Berlin and mostly work CET. We'd love to have you in the office with us, but if your experience is stellar we're happy to hire remote. We're scaling quickly, so this is a chance to join early and scale with us.
