About this role
We're Hiring: RF System Design Engineer
Full-Time | Core Team
LAT Aerospace | Defence
LAT Aerospace is developing next-generation aerospace systems from first principles. This includes a hybrid electric aircraft that takes off and lands within a space of a parking lot, Defence systems built from ground up and scalable Gas Turbine Engines.
Under the Defence program - we're building next-generation RF sensing - persistent, all-weather detection and tracking, fielded in months, not years. The challenge belongs to the RF chain: getting clean, wide-dynamic-range signal off the array so small, slow targets can be pulled out of clutter on deployable hardware. You'll own the chain from antenna to digitized samples, prototyping on SDRs so an idea goes from model to over-the-air in days. Because our architecture is software-defined, every improvement you make ships as capability.
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
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
