Level: Senior (individual contributor)· 

Focus: Full-stack hardware + flight stack integration (ArduPilot / Betaflight) 

Location: On-site (lab / hangar)

About the role

We're looking for an experienced hardware engineer to own end-to-end flight-control hardware integration across a diverse fleet of drones — from FPV quads to larger autonomous multirotor, fixed-wing, and VTOL platforms. You'll be the person who takes a new airframe from a pile of components to a tuned, flight-ready system: selecting and wiring the flight controller, flashing and configuring ArduPilot or Betaflight, integrating ESCs, sensors, radios, power, and payloads, and tuning it until it flies cleanly.

This is a hands-on, on-site role based in our lab/hangar, spanning the full range from quick R&D prototypes to repeatable production builds. You'll be the hardware integration expert for the team, working independently and setting the standard for how builds are configured, documented, and validated. Success looks like new platforms reaching reliable, flight-ready status quickly — and builds that stay consistent and reproducible from one unit to the next.

What you'll do

• Own end-to-end hardware integration of flight-control systems across multiple platform types (multirotor, fixed-wing, VTOL, FPV).
• Select, flash, configure, and tune ArduPilot (Copter / Plane / Rover) and Betaflight; build and maintain custom firmware targets and board definitions where needed.
• Integrate and validate flight controllers, ESCs, and motors — including protocol setup (DShot / bidirectional DShot, PWM / OneShot), motor–prop matching, and thrust testing.
• Bring up and calibrate full sensor suites: IMUs, barometers, compasses/magnetometers, GPS/RTK, rangefinders, optical flow, and airspeed sensors.
• Integrate RC and telemetry links (ExpressLRS, TBS Crossfire, CRSF / SBUS, MAVLink, SiK radios) and FPV/video systems (analog and digital VTX, OSD, cameras, antennas).
• Spec, assemble, and wire power systems — distribution, regulation, current/voltage sensing, and battery selection — with clean, reliable harnesses.
• Integrate smart peripherals over CAN / DroneCAN and companion computers (Raspberry Pi / Jetson) over MAVLink.
• Diagnose vibration, noise, and EMI issues and implement fixes (soft-mounting, gyro/notch filtering, grounding, shielding).
• Run bench, ground, and flight tests; analyze logs (Mission Planner / MAVExplorer, Betaflight Blackbox) and iterate on PID and filter tuning.
• Root-cause failures and design for reliability — diagnose in-flight and bench anomalies, build in redundancy where it matters, and harden platforms to hold up in real-world field conditions.
• Take platforms from quick R&D prototypes through to repeatable, well-documented production builds — locking in configurations and processes that stay consistent across units.
• Document build configurations, wiring, and setup procedures, and support/upskill the team so they can operate and iterate independently.

• Work closely with the software, mechanical, and flight-test teams to integrate cleanly and resolve hardware–software issues together.

   

What we're looking for

• Hands-on experience integrating and configuring ArduPilot and/or Betaflight on real hardware.
• Strong working knowledge of drone subsystems: flight controllers, ESCs, motors, sensors, RC links, power, and FPV.
• Comfortable with soldering, wiring, and general benchtop debugging (multimeter, bench power supply).
• Solid grasp of the relevant protocols: DShot, CRSF / SBUS, MAVLink, I2C / SPI / UART, and ideally CAN / DroneCAN.
• Experience tuning multirotor and/or fixed-wing platforms and reading flight logs to track down problems.
• Able to work independently and own a hardware domain from first component to flight-ready system.
• Comfortable switching between fast prototype iteration and the repeatability that production builds demand.
• Typically 4+ years in drone/UAV hardware, robotics, or embedded systems.

• Degree in electrical, aerospace, mechatronics, or robotics engineering — or equivalent hands-on experience.

   

Nice to have

• Writing custom ArduPilot board definitions (hwdef) or Betaflight targets, and compiling firmware from source.
• Familiarity with PCB design (KiCad / Altium) is a welcome bonus — but we treat full board design as a separate specialty, so it's not expected for this role.
• RTK GPS and precision navigation, lidar, or computer-vision payload integration.
• Breadth across airframe types — VTOL, large industrial, or agricultural platforms.
• Familiarity with the drone and aviation regulations that apply in the role's region.
• Comfortable with 3D printing and rapid prototyping for custom mounts, frames, and fixtures.

Tools & technologies you'll work with

• Firmware / stacks: ArduPilot, Betaflight
• Flight controllers: Pixhawk / Cube, Holybro, Matek, SpeedyBee, Kakute (STM32 F4 / F7 / H7)
• Ground stations: Mission Planner, QGroundControl, Betaflight Configurator
• Protocols: MAVLink, DShot, CRSF, SBUS, DroneCAN / CAN, I2C / SPI / UART
• RC / telemetry: ExpressLRS, TBS Crossfire, SiK radios
• ESC firmware: common ESC firmware and configuration tools
• Bench: Soldering station, multimeter, bench power supply

What we offer

• Competitive salary, set to experience
• A fully equipped lab and a budget for the gear, tools, and parts you need
• Health coverage, paid time off, and the standard benefits
• Room to grow your skills and shape how the team builds

Full compensation details are shared early in the process.

About us

We design and build drones across a range of platforms and applications, and we care about getting the hardware right. You'd be joining a hands-on team that puts real aircraft in the air and values engineers who can own their work from the bench to the flight line.

How to apply

To apply, send your resume along with anything that shows your work — builds you've integrated, logs or tuning you're proud of, repos, or flight videos. We'd love to see what you've put in the air.

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.
