Aetherflux is building the infrastructure to power and connect the orbital economy. Our satellites operate in Low Earth Orbit to collect sunlight and enable a new class of capabilitiesβfrom transmitting energy via infrared lasers (space-to-earth and space-to-space), to powering on-orbit compute, to delivering secure, high-bandwidth optical data. By rethinking how energy and data are generated and distributed in space, weβre unlocking entirely new ways to operate both in orbit and on Earth.
Founded in 2024 by Baiju Bhatt (co-founder of Robinhood), Aetherflux is backed by leading investors and built by a team from top aerospace and defense organizations. Weβre moving quickly to solve complex technical challenges and build a new category of space infrastructure.
The Role
Weβre looking for an Integration & Test Engineer to own the end-to-end validation of our hardware systems. You will be responsible for bringing up, integrating, and testing complex electro-mechanical and avionics systemsβensuring they perform reliably in mission-critical environments.
This role is highly hands-on and cross-functional, working closely with hardware, avionics, and software teams to take systems from prototype through flight readiness.
Responsibilities
- Own system-level integration and test of hardware and avionics systems
- Design, build, and maintain test infrastructure (racks, fixtures, harnessing, and tooling)
- Develop automated and manual test procedures for board- and system-level validation
- Lead bring-up and debug of electrical systems, including root cause analysis and failure investigation
- Execute environmental and functional testing (thermal, vibration, DVE, etc.)
- Collaborate cross-functionally with hardware, firmware, and software teams to validate performance
- Drive improvements in test coverage, reliability, and scalability of test systems
- Support flight qualification and launch readiness activities
- Support launch campaign operations including payload integration checkouts, pre-flight verification, and real-time anomaly resolution.
Basic Qualifications
- Experience with integration, test, or validation of hardware systems
- Strong hands-on experience with test automation, instrumentation, and lab equipment
- Experience building test setups: fixtures, harnessing, racks, and data acquisition systems
- Background in avionics board-level testing and debugging (power, signal integrity, communications)
- Familiarity with scripting (Python or similar) for test automation
- Experience with RF, sensors, LiDAR, or avionics systems is a plus
- Ability to read and interpret engineering drawings, schematics, and interface control documents
- Comfortable working in fast-paced, ambiguous environments with high ownership
Preferred Qualifications
- Experience supporting complex hardware or engineering programs
- Background in high-growth or deeply technical organizations
- Experience managing high-value spend portfolios or vendor-owned inventory agreements
- Familiarity with automation tools or process optimization within procurement workflows
- Prior experience in aerospace, space, or other frontier technology industries
- Background in environmental testing methods including thermal vacuum, vibration, shock, and EMI/EMC.
Compensation and Benefits
- Compensation and leveling will be determined based on experience and scope of role
- Equity in Aetherflux
- Employees and their eligible dependents may enroll in medical, dental, and vision insurance
