    “In high-risk operational environments, RU1's covert directional communication pathway, offers enhanced focus, reduced detectability, and increased resilience to electronic countermeasures. More than advanced technology, RU1 reflects our commitment to Europe’s strategic priorities - purpose-built for agility, precision, and operational relevance.”

    “The NATO Innovation Fund announced today that it has co-led an €11 million seed round alongside JOIN Capital to back TERASi, a Swedish spinout from KTH Royal Institute of Technology. The funding will help TERASi scale deployment of its wireless systems for unjammable and undetectable communication – a pressing capability gap for Europe. Other participating backers include In-Q-Tel and D3, and returning investors Navigare Ventures, Almi Invest, Onsight Ventures, Further Than Capital, and KTH Ventures.”

We build everything in-house: RF design, microelectronics, advanced packaging, manufacturing, and test. Whoever joins now isn't inheriting a finished machine — you're building it, alongside our design and RF engineers. You won't be maintaining someone else's production line — you'll be defining what \"production\" means at Terasi as we go from prototype to volume, owning the cleanroom process end to end with real room to grow as we scale. The Role You'll be the engineer who brings Terasi's products to life. This role sits at the intersection of R&D and production — you'll take designs from the lab into small-batch manufacturing, developing and refining the processes that get us there. Own small-batch production, prototype development, and process development/refinement in our cleanroom. Work closely with the design team to improve performance, create new solutions, and solve key technical challenges. Manage production and inventory, run QC, and maintain dialogue with suppliers and partners. Develop production tooling and process flows to increase yield and throughput. Take on significant scope as Terasi grows from prototype to volume production — this role grows with the company. Key Requirements Ph.D., or M.Sc. with 2+ years of relevant experience, in Engineering or Physics. Strong knowledge of microfabrication, clean room processing, 2nd level integration, microelectronics, and industrial manufacturing. Experience in cleanroom production at small-batch quantities, with an understanding of production management. Hands-on experience designing, characterizing, and troubleshooting production tooling and process flows. Familiarity with industrial-grade production tools and their requirements. Ability to formulate technical issues and solve them independently. Additional Requirements Good written and spoken English communication, documentation, and presentation skills. Programming skills — Python or MATLAB. Applications are reviewed on a rolling basis, so don't wait to apply. TERASi is a deeptech startup based in Stockholm, Sweden which offers unique components and packaging for high-frequency wireless applications. TERASi’s technology builds upon academic research at KTH Royal Institute of Technology and years of internal R&D. The company designs and manufactures all components from its Stockholm headquarters and now embarks upon a mission to scale their technology and bring it to mass markets.

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 isn't interest. It's that we don't 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. That's the job. You'll be the person who turns \"this is interesting, let's talk again\" into \"we've seen it work, here's a contract.\" What You'll Actually Do Sit in rooms with customers — sometimes a defence prime's 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 customer's stack on Wednesday, and demoing the whole thing on Thursday. Travel to customer sites in the US and across Europe. Sometimes you'll deploy and run a demo in the field. Sometimes you'll spend a week embedded with a prime's 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, you'll be operating with a lot of autonomy and short feedback loops. What We're Looking For This is a hybrid role — equally happy soldering a cable and writing the Python that ingests what comes out of it. We don't expect you to have done all of the below, but you should be credibly strong on most of it: Full-stack engineering instincts. You've built things end-to-end and you don't wait for someone else to define the interface. Hardware comfort. RF, comms, sensors, embedded systems — you've been around it. You're not scared of an oscilloscope or a radio link budget. Software fluency. Python is table stakes. You've 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 prime's chief engineer and earn their trust. You don't need a script. A bias for shipping. You've 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 don't wait for it to get clearer — you go figure out what they actually mean. We're open on seniority. If you're 4 years in and exceptional, we want to talk. If you're 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 Integration engineers from drone, robotics, or autonomy companies (typically Payload Integration, Flight Software, Ground Systems, or Integration Engineers at Auterion, Tekever, Quantum Systems, and similar) who've done real customer integration work. Forward Deployed / Mission Engineers from neo-defence companies (typically FDEs or FDSEs at Palantir; Mission Operations, Mission Software, or Mission Deployment Engineers at Anduril; and equivalent customer-facing engineers at Shield AI, Tekever, or similar). Engineers from RF, comms, or satellite companies (typically Firmware, Baseband, RF Systems, or Systems Integration Engineers at Bittium, Sivers Semiconductors, Gapwaves, Ericsson, Mynaric, or comms divisions at Saab, Leonardo, L3Harris, and Thales). Ex-military signals, EW, or comms officers (Signals Officers, Communications Officers, Electronic Warfare Officers, or Combat Systems Engineers) who've moved into engineering roles and miss being close to operators. Engineers from defence primes' rapid prototyping or skunkworks teams (typically Capability, Systems, Prototyping, or Applied Research Engineers) who are tired of the pace. What We're 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 haven't shipped to real users. Career salespeople with a technical veneer. People who need a fully scoped backlog before they can start. What You'll 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. You'll be one of the first commercial hires. Salary commensurate with experience — we'll calibrate to your level and the market.
