We're Hiring: RF System Design Engineer
Full-Time | Core Team
LAT Aerospace | Defence
At LAT Aerospace, we're building across multiple programs solving critical aerospace problems in India for the world - clean-sheet STOL aircraft, indigenous gas turbine engines, and defence autonomy that secures our borders. We're looking for an RF System Design Engineer to own the RF system end to end - from architecture and hardware through calibration and live field testing. You'll make the trade-offs, put your design on the bench, and watch it track real targets.
What you'll do
Own the end-to-end RF architecture: frequency planning, link/power budgets, cascade, dynamic range, and spurious analysis
Design the waveform and receive chain - chirp synthesis, LO generation, receiver lineup - driving phase-noise, linearity, and isolation to component level
Architect a software-defined approach: reconfigurable waveforms, sampling-friendly front-ends, clean RF-digital partitioning
Design and bring up T/R modules, RF front-ends, and antennas at element and array level - sidelobe control, pattern measurement
Define and execute multi-channel amplitude/phase calibration, from factory alignment to field
Simulate, fabricate, measure, correlate, iterate - validate against hardware relentlessly
Plan and run lab and field test campaigns through live target-tracking trials
Harden for thermal, vibration, EMI/EMC, and document to production-grade standards
What we're looking for
Hands-on RF system design in radar/defence electronics - firm requirement; telecom/5G-only will not qualify
At least one complete RF system taken from architecture through hardware to field testing
FMCW chain, phased-array/AESA design, and software-defined radar concepts
Antenna design at element and array level; microwave design at X, Ku, or Ka band
RF architecture analysis: link budget, cascade, frequency planning, spur charts, phase-noise budgeting
EM simulation (HFSS, CST, FEKO, AWR) and circuit/system simulation (ADS, Microwave Office, SystemVue)
Hands-on RF lab: VNA, spectrum analyzer, signal generators, phase-noise, power meters
Scripting for analysis and automation: MATLAB or Python
Eager to learn - treats "I haven't done this before" as a starting point, not a boundary
Bonus Skills
Pulsed architectures, or exposure to counter-UAS, EW, seekers, or surveillance radar
GaN/GaAs MMIC T/R module design; near-field antenna measurement
High-speed data converter integration (JESD204-class); MIL-STD-810/461 qualification
Experience in the Indian defence ecosystem (DRDO, defence PSUs, or defence startups)
Why LAT?
Core team opportunity at a high-conviction deep-tech startup
Real hardware, real field tests, real impact
Build sovereign defence technology from the ground up in India

What We Do
Imagine a world where flying is as easy as taking a bus. A world where air travel isn't just for the major cities, but for everyone, everywhere. No more congested hubs, no more wasted hours in security lines—just seamless, affordable, on-demand flights connecting thousands of destinations that the world has ignored for too long. We are building the future of mass aviation: a network of high-frequency, low-cost, 8 seater, STOL (short take-off and landing), medium-haul aircraft that make every city, every town, and every community accessible—without compromise. Powered by next-generation aircraft, designed ground-up for efficiency, built for affordability, and future-proofed for autonomy, we are aiming to rewrite the rules of flight. Our aircraft will take off and land in compact "air-stops" no bigger than a parking lot—no baggage belts, no security bottlenecks—eliminating the need for complex, expensive airport infrastructure that regional air travel simply doesn't require. No more waiting. No more detours. No more being forced to drive when you should be able to fly. This isn't the impractical supersonic future of aviation as you are made to believe. This is the real future of aviation that our communities need. --------- We are hiring We’re building a next-gen aerospace company — from scratch. Our Aircraft team is leading the development of our 8-seater hybrid-electric aircraft, spanning design, prototyping, systems integration, testing, and everything in between. Our GTE team is focused on building a world-class gas turbine engine. We're especially looking for folks with experience in turbines, rotors, control systems, or anything close.
