Responsibilities:
• Architect and build the telemetry, data, and operational software that runs Endurance's power plants on the seafloor and supports subsea deployment operations
• Make and execute the build, buy, and configure calls across PLM, ERP, MES, procurement, telemetry, and operational tooling
• Select, integrate, configure, and where required build the foundational software systems that run Endurance's manufacturing and supply chain
• Write production code, set engineering standards, and build the technical patterns that the broader software team will inherit
• Partner with engineering, manufacturing, supply chain, finance, and policy leaders to ensure the software roadmap maps to operational reality
• Establish cybersecurity, data governance, and development practices appropriate for a venture-backed company operating across federal, defense, and international markets
• As the first software engineer at Endurance, own the technical foundation that the broader software organization is built on
• Help shape the software organization as it grows, including interviewing and onboarding future engineers

• Strong build, buy, and configure judgment with hands-on experience selecting, deploying, or replacing industrial software systems such as PLM, ERP, MES, or procurement platforms
• Demonstrated ability to ship production software end to end, from architecture through deployment and operation
• Technical fluency strong enough to hold credibility with mechanical, electrical, and systems engineers
• Comfort being the first software engineer at a venture-backed company at sub-fifty headcount, including all the ambiguity that comes with it
• Ability to work onsite in Seattle and travel to deployment sites as required
Preferred:
• Experience inside hardware companies known for strong in-house industrial software, such as SpaceX, Anduril, Tesla, Hadrian, Helion, Shield AI, Saronic, Apex, Relativity, or Stoke
• Background in operational technology, SCADA, telemetry, or controls integration adjacent to physical hardware
• Experience with manufacturing execution systems, supplier development tooling, or quality data systems at scale
• Familiarity with cybersecurity frameworks relevant to defense and federal contracting (CMMC, NIST 800-171, FedRAMP)
• Prior experience standing up software for ITAR / EAR controlled environments
• Background in subsea, aerospace, defense, or other regulated hardware industries
