Product Manager

Epsilon3 is a multi-product operations management platform revolutionizing the way teams build, launch, and operate spacecraft and other advanced hardware systems.

Launched in 2021, our company is led by engineers from SpaceX, Google, and NASA, who have experience supporting over 100 space missions. Innovative teams at Blue Origin, Rocket Lab, Axiom Space, Firefly Aerospace, and many others depend on our web-based (SaaS) solutions to plan and track high-stakes procedures. We raised a $15M Series A funding round led by Lux Capital, Y Combinator (YC S21), and other world-class investors.

We’re looking for a Product Manager to own the strategy, roadmap, and execution for core areas of our platform, spanning procedure execution, manufacturing, test, telemetry & command, analytics, and AI-assisted workflows. You’ll work directly with our customers to turn complex, mission-critical problems into elegant, reliable products that operators trust in high-stakes environments. This is a high-ownership role within a fast-paced startup. The ideal candidate pairs strong product judgment with technical fluency, moves fast without breaking trust, and is energized by deep customer discovery alongside engineers, designers, and end users.

Write clear requirements, define success metrics, and prioritize a backlog that balances customer needs, business goals, and technical realities

Partner closely with engineering and design in a Lean/Agile environment to ship high-quality software rapidly and iterate with users

Translate complex workflows (such as real-time telemetry, procedure management, traceability, and AI-assisted decision-making) into intuitive, reliable experiences

Use data and analytics to measure outcomes, inform decisions, and continuously improve the product

Basic Qualifications

3-7 years of product management experience, including shipping complex B2B or enterprise SaaS, industrial, or technical software products

A track record of leading products end-to-end, from discovery and requirements to launch and iteration, with measurable impact

Strong product judgment, prioritization, and written communication skills; able to distill ambiguity into clear plans

Technical fluency. Comfortable reasoning about APIs, data models, integrations, and the constraints of real-time, high-security cloud/on-prem environments

Self-starter who thrives navigating ambiguity and rapidly evolving priorities; strong, collaborative team player

Bachelor’s degree in a technical, business, or related field

Experience with data analysis, PM backlog, document writing, presentation, and AI tools

Ability to work on-site at our El Segundo, CA headquarters

US Citizenship required (future security clearance may be required)

Preferred Qualifications

Domain experience in the markets we serve is a strong plus - aerospace, space, defense, manufacturing, energy, robotics, aviation, or other complex, mission-critical operations

Experience building AI/ML-enabled product features that boost team efficiency and enable fast, data-driven decisions

Experience with hardware, operations, mission-critical software, or regulated/high-reliability environments

Familiarity with Lean Startup and Agile product development methodologies

Experience at fast-growing tech startups
