RF System Design Engineer

LAT Aerospace Private; Bengaluru; On-site; INR 1,500,000 - 2,100,000; Full time

Job summary

LAT Aerospace is hiring an RF System Design Engineer to own the RF system end-to-end—from architecture to calibration and live field testing. You will balance trade-offs, put designs on the bench, and validate against targets in defence programs across India.

You will design waveforms, LO generation, receiver chains, and software-defined approaches for reconfigurable front-ends. The role demands hands-on lab work and readiness to travel for field trials.

Qualifications

• Hands-on RF system design in radar/defence electronics is essential.
• Experience taking an RF system from architecture to field testing.
• FMCW chain and phased-array/AESA design experience preferred.
• Antenna design at element/array level and microwave design in high bands.
• RF analysis: link budgets, spur charts, and phase-noise budgeting.
• EM and circuit simulations (HFSS/CST/FEKO/ADS; Microwave Office/SystemVue).
• Hands-on RF lab experience with VNA, spectrum analyzer, and signal generators.
• Scripting for analysis and automation in MATLAB or Python.
• Eager to learn and willing to tackle new challenges.

Responsibilities

• Own RF architecture end-to-end including frequency planning, budgets, and spurious analysis.
• Design waveform and receive chain; manage LO, chirp, and phase noise.
• Architect software-defined approaches for reconfigurable waveforms.
• Design and bring up T/R modules, RF front-ends, and antennas (element + array).
• Define multi-channel calibration from factory to field.
• Simulate, fabricate, measure, and validate against hardware.
• Plan and run lab and field test campaigns with live target tracking.
• Harden designs for thermal, vibration, EMI/EMC; document for production.

Job description

Overview

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.

Responsibilities

• 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

Qualifications

• 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)

Benefits

• 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
