Pune Employment Type:

Full-Time Experience Level:

5+ years (Senior)

At Altair, we are advancing frontier technologies across advanced sensing, autonomy, precision controls, and next-generation airborne systems. Our engineering teams support high-performance solutions for Unmanned helicopters, UAV/UDA platforms, and other aerospace and defence systems.

Role Summary We are seeking an Expert Analog Hardware Engineer with deep experience in designing, simulating, and validating high-performance analog and mixed-signal electronic systems. The candidate will lead product-level hardware architecture, own critical analog blocks, and guide junior engineers while working closely with cross-functional teams in digital, firmware, RF, and mechanical engineering.

Key Responsibilities

Analog & Mixed-Signal Circuit Design Design and optimize analog building blocks such as: precision amplifiers (op-amps, instrumentation, transimpedance, low-noise) ADC/DAC front-ends and signal-conditioning circuits filters (active/passive, low-noise, anti-aliasing, reconstruction) power stages (DC-DC, linear regulators, low-noise supplies) sensor interfaces (bridge, piezo, current/voltage sensing) Develop architectures for low-noise, low-distortion, and high-accuracy circuits.

Simulation & Analysis Perform SPICE simulations (AC, transient, noise, Monte-Carlo, corner analysis). Conduct signal integrity (SI), power integrity (PI), and noise analysis. Model real-world component behavior (parasitics, temperature effects, tolerances).

Hardware Development Create complete schematics, BOMs, and documentation. Work with PCB layout engineers; provide guidelines for: grounding schemes high-speed/low-noise routing impedance control thermal design isolation and safety compliance Perform worst-case analysis and derating for reliability.

Prototyping & Validation Bring-up and debug boards using: oscilloscopes, spectrum analyzers, VNAs, logic analyzers precision DMMs, SMUs, network analyzers Validate performance vs. design specifications. Conduct design verification testing (DVT) and root-cause analysis of issues.

Cross-Functional Collaboration Collaborate with embedded firmware and digital hardware teams. Support manufacturing and production test development. Review component choices for supply chain resiliency and cost optimization.

Compliance & Certification Ensure designs comply with EMI/EMC, safety, environmental, and regulatory standards: IEC/UL standards CISPR/EN noise emission standards ESD/Surge/ESD immunity Support certification processes with test labs.

Required Qualifications Master’s or PhD in Electrical/Electronic Engineering. 5+ years proven experience in analog/mixed-signal hardware design. Strong expertise in: analog circuit theory low-noise design precision measurement systems power electronics fundamentals Deep understanding of real-world effects: EMI/EMC, grounding, parasitics, layout impacts. Hands-on experience with lab test equipment. Proficiency in schematic & simulation tools (e.G., Altium, OrCAD, LTspice, PSpice).

Preferred Qualifications Experience with high-voltage/high-power analog systems. Experience with RF front-ends or high-speed ADCs/DACs. Experience designing for harsh or industrial environments and military environments. Familiarity with Python/Matlab for test automation.

Soft Skills Strong problem-solving and analytical thinking. Excellent documentation and communication. Ability to independently drive complex hardware projects. Attention to detail and passion for high-quality engineering.
