About the role

Backed by Founders Fund, Felicis, First Round Capital, and Point72 Ventures, our founding team includes veterans from SpaceX, Helion, and Robinhood.
We have completed multiple deep-ocean deployments and are launching a long-term demonstration project this fall.
You will work across mechanical, electrical, firmware, fluids, offshore operations, and manufacturing teams to bring first-of-a-kind systems from concept to validated hardware.

Own integration and test campaigns for complex mechanical, electrical, fluid, and subsea systems from initial bring-up through deployment readiness
Develop and execute test strategies, procedures, acceptance criteria, and operational plans for development, qualification, and field testing
Design and build test infrastructure including fluid systems, pressure systems, electrical harnessing, instrumentation, DAQ setups, fixtures, and integration tooling
Lead hazardous test operations involving high pressure, high voltage, rotating machinery, thermal systems, and offshore hardware
Drive system integration across multidisciplinary hardware including mechanical assemblies, fluid systems, controls, instrumentation, and power systems
Debug complex hardware failures and lead root cause investigations across mechanical, electrical, software, controls, and operational domains
Develop instrumentation plans and configure sensors, DAQ systems, telemetry, and automated test setups
Drive reliability improvements through failure analysis, operational feedback, test data review, and process standardization
Define and improve integration workflows, test processes, build standards, checklists, and operational readiness reviews
Work closely with responsible engineers to ensure designs are testable, manufacturable, serviceable, and operationally robust

7+ years of experience in integration, test, manufacturing, reliability, or systems engineering roles involving complex hardware systems
Strong hands-on experience with mechanical systems, fluid systems, instrumentation, electrical integration, or electromechanical hardware
Experience planning and executing hazardous testing involving pressure systems, thermal systems, power systems, rotating machinery, or equivalent high-energy hardware
Ability to read and interpret engineering drawings, schematics, P&IDs, wiring diagrams, and assembly documentation
Strong systems-level thinking and ability to identify operational and reliability risks early
Excellent communication skills and ability to coordinate across engineering, operations, manufacturing, and field teams
Demonstrated experience leading integration and test efforts for multidisciplinary hardware programs
Strong troubleshooting skills across hardware, controls, instrumentation, and system interactions
Experience designing and building test infrastructure, tooling, fixtures, or automated test systems
High ownership mindset with the ability to independently drive complex technical efforts under aggressive timelines
Willingness to travel and support offshore and remote field operations as needed

Experience in aerospace, subsea, marine, energy, launch vehicle, or other high-performance hardware environments
Familiarity with DAQ systems, controls integration, telemetry, and automated testing
Experience with environmental testing, vibration testing, thermal testing, or qualification campaigns
Experience with root cause analysis methodologies and reliability engineering practices
Background in manufacturing engineering or production test operations
Hands-on fabrication experience including machining, welding, tube bending, or structural assembly
Experience supporting offshore operations, vessel-based testing, or remote field deployments
Familiarity with high-reliability fluid system standards and practices including Swagelok or equivalent systems
Experience operating in fast-paced prototype development environments with minimal process overhead
