This Job Is No Longer Available

Why this role exists

We build Radio Units (RUs) that work as high-speed, secure, jam-resistant data pipelines for defence and dual-use applications — the connective tissue for UAV C2, deployable 5G, and tactical awareness systems.

Our pipeline is full of customers — defence primes, armed forces, industrial operators — who are excited about what our RU could do for them. The bottleneck isnt interest. Its that we dont have enough hands to sit with those customers, understand their actual problem, build something that proves it, and spot the patterns before anyone else does so we can feed them into our product roadmap. Thats the job. Youll be the person who turns "this is interesting, lets talk again" into "weve seen it work, heres a contract."

What Youll Actually Do

• Sit in rooms with customers — sometimes a defence primes systems architect, sometimes a signals officer, sometimes both — and figure out what they actually need (which is rarely what they first asked for).
• Scope and build PoCs and demos that integrate our RU with whatever the customer cares about: cameras, radars, microphones, ground stations on one end; data lakes, AI tooling, C2 software on the other.
• Do the integration work end-to-end. That means wiring a physical kit on Monday, debugging a MAVLink message on Tuesday, writing Python to push sensor data into a customers stack on Wednesday, and demoing the whole thing on Thursday.
• Travel to customer sites in the US and across Europe. Sometimes youll deploy and run a demo in the field. Sometimes youll spend a week embedded with a primes engineering team.
• Feed what you learn back into product. The patterns you find — the integrations customers keep asking for, the operational constraints that keep showing up — are how we figure out what to build next.
• Work directly with our CEO on the highest-priority opportunities. Until our CCO is in seat, youll be operating with a lot of autonomy and short feedback loops.
  
  

What Were Looking For

This is a hybrid role — equally happy soldering a cable and writing the Python that ingests what comes out of it. We dont expect you to have done all of the below, but you should be credibly strong on most of it:

• Full-stack engineering instincts. Youve built things end-to-end and you dont wait for someone else to define the interface.
• Hardware comfort. RF, comms, sensors, embedded systems — youve been around it. Youre not scared of an oscilloscope or a radio link budget.
• Software fluency. Python is table stakes. Youve worked with data pipelines, APIs, and at least one of the things our customers care about: drone autopilots (MAVLink, STANAG 4586), sensor fusion, edge processing, AI/ML inference at the edge, ground control stations.
• Customer-facing presence. You can sit in front of a colonel, a procurement officer, or a primes chief engineer and earn their trust. You dont need a script.
• A bias for shipping. Youve built demos and prototypes under time pressure. You know the difference between "demo-good" and "production-good" and you make the right call for the situation.
• Comfort with ambiguity. Customer says something vague. You dont wait for it to get clearer — you go figure out what they actually mean.
  
  

Were open on seniority. If youre 4 years in and exceptional, we want to talk. If youre 10 years in and want to be hands-on at a stage where what you build defines the company, we want to talk.

Background that fits

This Is Illustrative, Not a Checklist

• Forward Deployed Engineers from Palantir, Helsing, Anduril, Shield AI, Tekever, or similar.
• Engineers from drone / robotics / autonomy companies (Auterion, Tekever, etc.) whove done real customer integration work.
• Hardware/software hybrid engineers from RF, comms, or satellite companies (Comms division at Bittium, Leonardo, L3 Harris, Saab etc.).
• Ex-military signals, EW, or comms officers whove moved into engineering roles and miss being close to operators.
• Engineers from defence primes rapid prototyping or skunkworks teams who are tired of the pace.
  
  

What Were Not Looking For

• Solutions Engineers from SaaS who are used to a defined demo script and a clean handoff to a CSM.
• Pure researchers or lab engineers who havent shipped to real users.
• Career salespeople with a technical veneer.
• People who need a fully scoped backlog before they can start.
  
  

What Youll Get

• A seat at the table while we build the commercial function from scratch. The PoCs you build will define our product roadmap and our first multi-million-euro contracts.
• Direct working relationship with the CEO and the rest of the founding team.
• Real customers from week one. We have live opportunities in UAV C2 and deployable 5G that need an FDE on them today.
• Equity that reflects the impact. Youll be one of the first commercial hires.
• Salary commensurate with experience — well calibrate to your level and the market.
