Job Description

Title:

Lead Satellite Systems Engineer

Industry:

Space Technology

Location:

Ahmedabad

Role Type:

Full-time

Experience:

6-12+ years

About the Role:

You will serve as a senior systems engineer responsible for the architecture, technical integrity, performance, and end-to-end delivery of spacecraft supporting our SAR constellation. You will lead requirements flow-down, system-level integration, AIT readiness, launch and commissioning support, and in-orbit performance optimisation.

You will work across payload, platform, ground, and operations teams, and act as a key interface to vendors, subsystem suppliers, and launch providers.

Responsibilities:

System Architecture & Requirements Leadership Own system-level architecture for new SAR spacecraft and constellation increments. Lead requirements definition, flow-down, verification planning, and traceability across all spacecraft subsystems. Ensure payload (SAR) system requirements are translated into clear bus-level specifications (power, thermal, data, pointing, RF/TTC). Conduct system-level trade studies (SWaP trades, power/thermal margins, data throughput, SAR duty-cycle optimisation). Technical Leadership Across Lifecycle Guide design development across AIT, Payload, ADCS, Comms, Thermal, Power, and Ground Segment teams. Lead design and readiness reviews: SRR, PDR, CDR, MRR, ORR. Evaluate vendor designs, architectures, and test results for compliance. Manage internal and external interface definitions via ICDs and configuration control. Constellation Engineering Support architecture for constellation scale-up:

~orbital plane selection,

~performance/capacity planning,

~inter-satellite coordination,

~latency & coverage modelling.

Validate mission simulations and satellite-to-ground data flows. AIT, Launch & Commissioning Oversight Provide technical oversight for Assembly, Integration & Test (AIT) execution, NCR resolution, and configuration management. Support launch readiness, pre-ship reviews, environmental test campaigns, FDIR planning. Lead technical activities during LEOP & Commissioning, ensuring the satellite meets performance metrics. Contribute to in-orbit anomaly investigations and corrective action implementations. Vendor & Stakeholder Management Act as a primary technical interface with:

~spacecraft bus vendors,

~subsystem suppliers,

~launch providers,

~ground segment partners

Review vendor deliverables, analyses, and test data. Support contracts, SoWs, RFPs, technical evaluation, and acceptance milestones. Mentoring & Process Development Guide junior systems engineers on modelling, trade studies, documentation, and design fundamentals. Improve systems engineering processes: requirements management, V&V frameworks, model-based engineering, risk management.

Minimum Qualifications

BE/BTech in Aerospace Engineering (mandatory) MTech/MS in Aerospace/Space Engineering (optional) 6-12+ years experience in space systems engineering. Must have 1-2 satellite missions delivered through at least these stages: SRR/PDR/CDR cycles, AIT campaigns, launch & early orbit operations, commissioning into nominal operations. Strong analytical and troubleshooting skills. Excellent written and verbal communication

Knowledge & Skills

Deep understanding of spacecraft subsystems and bus-payload integration. Hands-on experience with: mission analysis tools (STK, GMAT, Orekit), systems modelling (MATLAB/Python), ICD development, SWaP & link budget analysis, environmental test methods (TVAC, vibe, EMI/EMC). Strong understanding of orbital mechanics and LEO mission constraints. Familiarity with SAR payload constraints and RF considerations (preferred).

Preferred Qualifications (Nice to Have, Not Required)

Experience with commercial SAR missions or RF-intensive payloads. Experience with MBSE tools (SysML, Cameo). Experience working with ISRO, NSIL, and/or global ground station & launch providers. Exposure to constellation operations or multi-satellite deployment.

Soft Skills & Attitude

Ownership mindset--comfortable with ambiguity and responsibility. Ability to lead cross-functional engineering efforts. Strong documentation, review, and communication abilities. Experience presenting to executives, partners, and technical review boards.

Why Join Us?

Shape India's next-generation SAR constellation from the ground up. Lead high-impact missions with national and commercial significance. Direct influence on spacecraft design, operational reliability, and fleet capability. * Opportunity to grow into Chief Engineer / Systems Architect roles.
