Application Process

1.     Apply with your CV and a brief cover letter explaining your interest and relevant experience

2.     Interview with the Recruiter and CFO

Do you work with bare-metal C/C++ and embedded algorithms where every millisecond and byte of memory matters? A team developing interceptor drones has opened an office in central Vilnius and is looking for an Embedded Radar Engineer to work with radar algorithms, SoC, FPGA/DSP, and RTOS.

We build miniature radar seekers. You have to extract small, low-RCS drone tracks from heavy background clutter, EW interference, and motor noise. You have to run this math on severely constrained silicon. You are bound by strict compute, memory, and thermal limits. The processing loop must close in milliseconds. There is no cloud, no heavy GPU, and no room for inefficient code.

Main Responsibilities

You own the math and the metal. You design the radar algorithms (FMCW, CFAR, beamforming, MIMO virtual arrays) and the advanced tracking math (Kalman filters, multi-target tracking, clutter rejection). You implement this across the SoC architecture – managing the heavy lifting on FPGA and DSP accelerators and writing the bare-metal C or RTOS code for the microcontrollers. You manage the memory architecture, the DMA transfers straight from the ADCs, and the low-level peripheral drivers. You also own the data handoff, packaging clean point-clouds and track histories for our Edge ML classification models.

PROOF OF EXECUTION
Degrees do not matter here. We want to see the algorithms you have built AND physically deployed on embedded hardware. If you only simulate perfect radar returns in MATLAB and have never managed a memory buffer or a DMA transfer, do not apply. Show us how you squeezed complex tracking math into a constrained chip (FPGA, RFSoC, or MCU) without blowing up the latency. We expect you to take raw field data on a Tuesday, rewrite the algorithm, and flash a new firmware image to the seeker on a Thursday.

Mandatory Requirements

You must work in our Vilnius lab every day. We go from the bench to field testing in days, not months. The financial package includes a top-of-market base salary, founding equity, a relocation bonus, company housing, and a daily allowance. We cover all logistics and remove all friction so you can focus 100% on building hardware.

We offer

This role requires your daily physical presence in our Vilnius lab. We move from the test bench to live field validation in days, not months. We provide a top-of-market base salary, founding equity, a relocation bonus, company housing, and a daily allowance. We remove all financial and logistical friction so you can focus entirely on shipping hardware.

A European defense and aerospace company is hiring a Founding Hardware Engineer for its Vilnius office. We design miniature radar seekers. Everything has to fit on a single board: high-frequency RF, high-speed digital lines, and dense power regulation — while keeping digital noise out of the analog front-end. If it doesn’t, the radar goes blind. Thermal density, EMI, and tight mechanical constraints have to be solved together.
 

We are looking at candidates in Vilnius and elsewhere in Europe. Relocation is fully covered: move, housing, and official employment.
 

Main Responsibilities

• Own the physical board end-to-end, from schematic to bench bring-up.
• Select components against real stock and lead times — no waiting 10 weeks for a PMIC.
• Design the multi-layer stackup (6 layers) and calculate impedance.
• Route RF traces, high-speed digital lines, and the power delivery network.
• Define via stitching, RF cans, and the grounding scheme.
• Align board outlines and thermals directly with the mechanical engineer.
• Make minor revisions to the existing V1 board (schematic and purchased chips are already in place).
• Design the V2 radar boards from scratch. Form factor: a module of 3 round PCBs that fits inside the drone’s nose radome.
• Bring the board up in the lab when it returns from fabrication. Debug with a scope and a soldering iron.
   

Mandatory Requirements

• Independently designed 5+ boards, solo, end-to-end.
• Proficient in Altium or KiCad.
• Hands-on experience probing and soldering your own boards. Simulation-only or outsourced layout is not a fit.
• Background in one of: telecom / 5G, high-complexity IoT, electronic warfare, UAV avionics, or automotive radar.
• One full-cycle engineer who combines layout and RF. We will not hire a layout engineer and an RF engineer separately, and we will not consider an RF engineer without layout experience.
• Self-taught candidates are welcome if they can show strong, low-level signal integrity and PCB design.
• Be ready to walk through screenshots of your most complex past layouts in the interview.
• Work on-site daily in the Vilnius lab.
   

We offer

• Top-of-market base salary.
• Founding equity.
• Full relocation package (move, housing, official employment) for candidates relocating from other cities or countries.
• Daily allowance.
• Logistics handled so you can focus on the hardware.

You own the radar architecture from the waveform math to the physical antenna.

Main Responsibilities

You own the radar architecture from the waveform math to the physical antenna. You define the fast-chirp FMCW parameters and the detection strategy, including range-Doppler processing, CFAR, and angle estimation. You set and manage the system budgets for SNR, power, and thermals. You select the frequency band and design the physical antenna elements. You prototype integration approaches like substrate-integrated waveguide and launch-in-package. You design corporate-fed and series-fed networks, controlling amplitude and phase to hit specific beamforming and sidelobe targets. You design MIMO arrays, managing element spacing, channel isolation, and virtual-aperture formation. You build the digital twin of the sensor to track real-world phase noise, PA compression, quantization, and mutual coupling.

Mandatory Requirements

We do not look at your degrees. Show us the hardware you built and tested. If you have only built a single antenna in your career and simulated the rest of the system, do not apply. We want a track record of shipped physical artifacts. You must provide measured data from a VNA or anechoic chamber to prove your designs work in reality. Speed wins over perfection. You must parallelize your work streams. There is no time for sequential engineering. Show us how you move fast, solve phase-coherence problems in physical hardware, and correlate measured results against your EM simulations.

We offer

This role requires your daily physical presence in our Kyiv lab. We move from the test bench to live field validation in days, not months. We provide a top-of-market base salary, founding equity, a relocation bonus, company housing, and a daily allowance. We remove all financial and logistical friction so you can focus entirely on shipping hardware.
