Background

I am a Senior Electrical Engineer at Pixxel, working on power electronics for Earth observation satellites. My work spans the full hardware lifecycle — from architecture and schematic design through PCB layout, EM and FM build, environmental testing, and on-orbit commissioning.

My focus is EPS and PCDU design for LEO missions: DC-DC converter topology selection and stability analysis, fault-tolerant power distribution, and radiation-tolerant COTS component qualification. I work to ECSS, NASA, and ISRO standards across all phases of development, and I've run Bode plot analysis and production sign-off on 11 flight converters across 6 operational satellites.

I approach hardware the way most engineers approach a puzzle they can't put down. Instinct and understanding first — why does the circuit behave this way — simulation to confirm. I build things outside work because the problems don't stop when the working day does.

Based in Bangalore, open to relocation worldwide for the right opportunity — one that means getting hands dirty in the lab, building and testing real hardware.

Work History

Senior Electrical Engineer Current
Pixxel · Bangalore, India
Jan 2025 — Present
  • Leading EPS and PCDU architecture for an 8-satellite sub-200 kg EO constellation — full ownership from topology selection through component qualification, detailed design, and hardware testing across PDR, CDR, TRR, and FRR.
  • Designing gyroscope package board electronics around the NXP S32K MCU and ASIL-D rated Safety PMIC — architecture definition, schematic, CAN FD integration, and BOM closure; hardware bring-up in progress.
  • Developed a systematic COTS qualification methodology using published radiation data (CERN, DOE, IUAC) — cut component costs by over 90% and hardware lead times from 16–18 weeks to under 3.
  • Raised end-to-end bus conversion efficiency from 85% to 93% through topology selection and compensation network optimisation.
  • Built EPS performance monitoring and requirements traceability tooling in Python, analysing fleet telemetry across 6 operational satellites for subsystem health monitoring and anomaly detection.
  • Coordinated with ISRO, vendors, and manufacturers on supply chain alignment, regulatory compliance, and mission-critical schedule milestones.
Electrical Engineer
Pixxel · Bangalore, India
Jun 2021 — Dec 2024
  • Designed end-to-end EPS and PCDU for the Firefly LEO constellation (6 satellites, 5-year mission / 7-year design life) — zero major power anomalies during on-orbit commissioning.
  • Designed DC-DC buck converters, custom power switches, and motor drivers; achieved 10–12% efficiency improvement through topology selection and component optimisation.
  • Performed loop stability analysis (Bode plots, phase and gain margin) on flight converter designs; validated compensation networks and signed off 11 converters for production.
  • Led FMECA at hardware and architecture level; reviewed system-level FMECA with cross-functional team, enabling fault-tolerant FDIR implementation.
  • Oversaw multilayer PCB design for IPC Class 3 flight boards up to 12-layer; personally executed schematic design and 4-layer PCB design; reviewed layouts against ISRO PAX and ECSS requirements.
  • Defined grounding architecture per NASA-HDBK-4001 and applied EMI filter design to ECSS/NASA standards, measurably reducing integration anomalies.
  • Conducted flight battery pack testing and characterisation; performed solar panel testing including illumination testing, ELM characterisation, and diode continuity checks.
  • Implemented CAN-based hardware interfaces for power subsystem telemetry; diagnosed and resolved CAN bus faults across hardware revisions.
  • Oversaw V&V campaigns (board bring-up, Bode analysis, TVAC, vibration) and mission operations readiness (DITL simulations, full dress rehearsals).
Electrical Engineering Intern
Pixxel · Bangalore, India
Feb 2021 — Jun 2021
  • Simulated and validated protection circuits (UVLO, OVLO, latch-up limiters, power monitoring) for space-grade EPS designs in LTSpice and TINA.
  • Supported EM prototype bring-up, gaining foundational experience in space hardware reliability processes.

Personal Work

In Progress
PSFB SMPS — 300 W Reference Design

Personal design of a phase-shifted full-bridge SMPS targeting 300 W, 0–60 V CV/CC output. Design covers converter topology, synchronous rectification, current-doubler rectification, transformer design, and closed-loop compensation. STM32G474 supervisor. Intended as an openly published reference design — the kind textbooks describe but rarely show end-to-end.

Astronomy & Space Science

Carl Sagan got me here. The Voyager missions — two spacecraft still transmitting from interstellar space — remain the most extraordinary engineering achievement I know of. The idea that humans built something that will outlast every institution on Earth is the reason I work in hardware.

Planning a 12" f/5 Dobsonian. A slow project — updates on GitHub when there's something worth showing.

↗ Upcoming: Hydrogen line radio telescope, backyard cosmic ray detector

Formula 1

Closely follow the engineering side of F1 — power unit development, aerodynamic philosophy, and the systems integration challenges that define competitive performance. The intersection of extreme reliability and extreme performance is exactly the problem space I want to work in professionally.

Trains

I love trains. That's it, that's the tweet.

Get In Touch

I am currently looking for roles in European space companies, motorsport and F1 teams, and aerospace & defence firms. If you are working on hardware that needs to survive launch loads, radiation, or extreme environments — I would like to hear about it.

I am also happy to connect with other engineers, makers, amateur astronomers, and anyone with an interest in the things on this page. No agenda required.

Open to Opportunities

Actively pursuing roles in 2026. Interested in positions focused on power electronics for demanding applications — space systems, motorsport, or high-reliability aerospace and defence hardware. Open to relocation worldwide. At my best when the work involves getting hands dirty in the lab — building, testing, and debugging real hardware.
