Jobs Engineering / Hardware

Antenna / RF Front-End Engineer (Contract)

About the Role

You'll design the antenna and RF front-end at the heart of a counter-UAV radar sensor — radiating elements, arrays, and feed networks — taking them from concept through EM simulation to measured validation. This is a contract engagement, so you'll need to work independently and contribute quickly. We care most about breadth across antenna design methods on a master's-level foundation; senior experience is a strong plus. You'll have access to high-end measurement facilities — including anechoic-chamber time in Kyiv (paid travel) — to characterize and iterate on real hardware, not just simulate. This is a key role to ensure our first launch cements our reputation in the industry  - make your mark with Valkyrie!

What You'll Do

• Design and optimize antenna elements and arrays — single-element and phased-array — for mmWave operation
• Evaluate tradeoffs across frequency bands and packaging: select the band and topology that best balance range, resolution, aperture size, and environmental performance for a given sensing requirement
• Design corporate-fed and series-fed feed networks for phased-array and MIMO systems, controlling amplitude/phase distribution to hit beamforming, sidelobe, and radiation-pattern targets
• Prototype and compare integration approaches — substrate-integrated waveguide (SIW), launch-in-package, and alternatives — to find the best fit for compact integration
• Model and optimize performance — gain, beamwidth, sidelobe level, VSWR/S11, mutual coupling, scan range, grating-lobe behavior — against sensing requirements
• Design MIMO arrays for multi-channel sensing: element spacing, channel isolation, and virtual-aperture formation for angular resolution
• Validate designs on the bench (VNA, anechoic/OTA range), correlating measured results against simulation and documenting deviations
• Work directly with the DSP and radar-systems engineers we're hiring in parallel — antenna, signal processing, and architecture designed together, not in isolation. You'll have real influence over the system design, not just your own slice
• Design to the RF front-end architecture — channel count, transceiver interface, phase coherence — and feed antenna feasibility back as the system evolves
• Prepare finished antenna and feed-network designs for handoff: specify antenna-critical constraints and review layout through bring-up

Required Qualifications 

• Master's in Electrical Engineering, Microwave/RF Engineering, or a closely related field — or equivalent hands-on antenna design experience with the skills below. PhD a plus
• Prior work on radar or RF sensing systems, not communications-only antenna work
• Hands-on experience across multiple antenna design methodologies: SIW, launch-in-package, phased arrays, MIMO systems, series-fed and corporate-fed networks. Breadth here matters more to us than years
• Strong feed-network fundamentals: power dividers, phase shifters, impedance matching, loss/isolation and beam-squint tradeoffs
• MATLAB/Simulink for array-factor synthesis, pattern analysis, and beamforming/system-level modeling (e.g. Antenna and Phased Array System Toolboxes)
• A track record of carrying designs from concept through simulation, prototyping, and measurement validation — not simulation alone.
• Proficiency with EM simulation software (HFSS, CST Microwave Studio, or equivalent)

Preferred / Bonus

• Working knowledge of multilayer PCB constraints (stackup, manufacturability) — enough to hand off cleanly to a PCB engineer

Engagement Details

• Type: Contract / consulting
• Rate: [TBD]
• Duration: [TBD]
• Location: Remote/Hybrid
  • Hybrid: Temporary travel to Kyiv for on-site testing, heavily preferred (expenses paid) — primarily anechoic-chamber characterization of candidate designs, with possible field testing.
• Long-term: Strong performance could lead to an ongoing or permanent role.
• Start: ASAP

About the Role

We've already proven the concept of a counter-UAV radar sensor with a first-generation prototype. This role owns the redesign that carries those lessons into a production-grade sensor, architected from requirements up, with the systems planning to do it right. You'll also own the system architecture, from the waveform, detection strategy to the system-level requirements and budgets that define it. You'll drive the RF chain and transceiver architecture hand-in-hand with the antenna engineer, converging on what's actually feasible to build while setting the DSP chain direction. Your success is our success - make your mark with Valkyrie Dynamics.

What You’ll Do

• Own the radar waveform and detection strategy
  • Chirp/FMCW design
  • Range-Doppler processing detection budgets (SNR, integration, CFAR)
  • Angle estimation to detect small, low-RCS UAV targets at high closing velocity
• Define and maintain the system-level requirements and budgets
  • Detection range, range/Doppler/angular resolution, update rate, power, thermal, and size
  • Write verifiable requirements so that meeting them validates the sensor
• Evaluate approaches across the integration spectrum, cascaded transceiver ICs, an integrated system-on-module, or a discrete RF front-end
  • Collaborate with the antenna engineer on a viable solution for channel count, LO/clock distribution, and phase-coherence strategy across the array
• Own and control the interfaces between subsystems
  • Ensure end-to-end signal chain from antenna to detection output holds together as one coherent system including:
    • Timing and synchronization (frame/trigger)
    • Transceiver-to-compute data path (sample rates, formats, latency/throughput)
    • RF/antenna boundary
• Own and continuously evolve the system model — effectively a digital twin of the sensor. During the evolution:
  • Maintain ICDs
  • Meet and manage performance metrics
  • Grow model fidelity over time, introducing the non-idealities and non-linearities that matter as complexity increases (phase noise, PA compression, quantization, channel mismatch, mutual coupling), and trace observed behavior back to the origin.
• Collaborate with the DSP engineer on the waveform and detection design
  • You lead the strategy, they own the implementation and pressure-test it for compute load, memory, and timeline — until the architecture is both performant and buildable
• Converge the open architecture questions to decisions on a schedule
  • Committing with the evidence available, revisiting only when new data (a budget, a measurement) actually changes the answer

Required Qualifications

• Radar systems you’ve architected and shipped end-to-end — from waveform and detection through the RF chain
• Strong grounding in radar detection theory
  • FMCW/chirp waveforms, range-Doppler processing, CFAR and SNR/integration, and angle estimation
  • Target-tracking fluency to set the requirements (update rate, track accuracy)
• Hands-on MATLAB for system-level radar modeling (Radar Toolbox) — you’ve built and evolved system models, not just read their output
• Track record personally owning and closing the quantitative budgets 
  • Link and detection budgets above all — and holding the design to them
• RF chain architecture experience with multi-channel/MIMO transceivers and the coherence challenges of scaling channel count, from LO/clock distribution to phase alignment across the array
• Able to work independently on a contract basis
• Must pass company security procedures
• Must communicate effectively in English

Preferred / Bonus

• Counter-UAV or defense radar experience specifically — small, low-RCS, maneuvering targets in cluttered environments
• Hands-on experience with integrated radar transceiver SoCs including integration tradeoffs they bring
• MATLAB Simulink

Engagement Details

• Type: Contract-to-permanent position
  • Starts as a contract engagement with an explicit track to a permanent lead role for the right candidate
• Rate: [TBD]
• Duration: [TBD]
• Location: Remote/Hybrid
   
  • Hybrid: Must be able to temporary travel to Kyiv for on-site testing is heavily preferred (all expenses paid) — system bring-up and field validation against real targets, correlating measured performance against the model.

Credibility
In four months we went from concept to a robust missile prototype — smaller and cheaper than anything comparable, fireable with one hand, reliably intercepting FPV drones. Recent work includes working with the Ukrainian armed forces to go from pre-idea to warhead design, production and live-fire testing in 24 hours; car-mounted missile testing at 200 km/h; building an air cannon in two days then destructively testing 50 missiles to diagnose a hardware issue; and six launches in a single day with design iterations between each.

Our team is from the Special Forces, Stanford, 1X, Imperial College, FLIR, student engineering teams and non-traditional paths. What we share is the ability to build real systems fast, take ownership and work toward a safer Europe.

ElevateOS integrates with 20+ smart-device ecosystems — keyless entry, locks, cameras, switches, thermostats. Every integration is validated against physical hardware before release. We're hiring the person who owns that entire pipeline: the device lab itself, the test environments and servers behind it, and the integration testing that runs on top.

Who we need: someone technical who can host and run a physical device lab from their home in Kraków — smart locks, cameras, access-control hardware — and also handle the server/networking side so our developers can remotely connect to and test against that hardware.

You'll build and run your own hardware lab — smart locks, cameras, access control systems, and the servers and test environments behind them. Every device integration we ship passes through your hands before it reaches production, and you'll work directly with the development team and CTO with real autonomy: you decide how the lab, its environments, and its tooling evolve. The role spans mobile, backend, networking, and physical hardware — a breadth almost no single position offers. If you're the type who runs a home lab for fun, this is that, with a company budget behind it.

About ElevateOS

ElevateOS has been improving the resident experience for over seven years. We built a single, all-in-one platform that lets property managers and resident staff work together, replacing multiple confusing apps with one intuitive solution. The product is stable, growing, and US-based. Our stack is JavaScript end to end: React, Node.js, and React Native.

What you'll own:

- The physical device lab — smart locks, access-control hardware, cameras, switches — hosted at your home in Kraków. Setup, configuration, firmware updates, troubleshooting, and inventory.

- Test environments and servers — install, configure, and maintain the local and staging environments our integrations run against; adjust configurations live during debugging sessions with developers.

- Lab networking — device connectivity (Wi-Fi, BLE, Zigbee/Z-Wave), router and network configuration, and remote access so the dev team can reach devices and environments from anywhere.

- Integration testing — install iOS/Android builds, run end-to-end tests against physical devices, API testing, reproduce and isolate bugs, verify fixes with the team.

- Documentation — device matrix, environment runbooks, test protocols, and findings.

Requirements:

- Based in or near Kraków — the hardware lives with you; the work is otherwise remote.

- Solid Linux and networking fundamentals: comfortable in a terminal with SSH and logs, and with DNS/DHCP/port-level debugging.

- Experience setting up and maintaining servers or local test environments (Node.js ecosystem and Docker familiarity as a plus).

- Hands-on comfort with hardware, physical devices and space at home to host the lab.

- Able to read code (JavaScript/TypeScript), work with APIs (curl, Postman), and read mobile logs.

- Commercial experience (2+y) in a technical role — engineering, QA, sysadmin/devops, technical support.

- Strong troubleshooting instincts and good English communication.

Nice to have:

Exposure to React Native, Kotlin, or Swift; mobile SDK integrations.

Familiarity with smart locks, access control, or keyless entry ecosystems.

MQTT, webhooks, RTSP/video streaming.

Test automation experience; CI/CD (GitHub Actions).

Practical details:

Company hardware is currently distributed across two locations in Kraków and will be consolidated with you during onboarding.

Occasional in-person device handoffs in Kraków.
