About The Position

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 capabilities—from 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, we’re 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. We’re moving quickly to solve complex technical challenges and build a new category of space infrastructure. We’re 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 systems—ensuring 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.

Requirements

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
Ability to read and interpret engineering drawings, schematics, and interface control documents
Comfortable working in fast-paced, ambiguous environments with high ownership

Nice To Haves

Experience with RF, sensors, LiDAR, or avionics systems is a plus
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.

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.
