What the job involves

• The Mission Dev team operates at the intersection of cutting‑edge software engineering and critical customer missions
• As a Software Engineer on Mission Dev, you won’t just support customers — you’ll embed with them to solve their hardest data challenges head‑on
• Think like a startup cofounder or an early‑stage CTO: you’ll dive into ambiguous problem spaces, own solutions end‑to‑end, and iterate rapidly to deliver impactful results
• This role demands grit, strong engineering foundations, creativity, and the ability to thrive in dynamic environments where you’ll be responsible for everything from understanding core user needs to writing code for data integrations and custom applications
• You’ll be a pivotal force within Nominal’s Mission organisation, directly applying your technical expertise to ensure our customers succeed with the platform and achieve their mission objectives
• If you’re a builder who loves solving complex problems, seeing your code directly shape mission outcomes, and forging paths in new territory, this is where you’ll excel
• Build and deploy custom applications, scripts, and extensions to meet specific customer requirements and unlock new capabilities — with a bias towards action and rapid prototyping
• Design and implement resilient data pipelines and integration workflows to connect diverse customer systems with Nominal’s offerings, often in complex or novel environments
• Work closely with our Sales and Mission Ops teams to ensure seamless customer handoffs, provide deep technical expertise during pre‑sales conversations, and scope customer engagements effectively
• Gather customer feedback and insights from the field to inform product development, influence Nominal’s roadmap, and improve our offerings
• Contribute to team growth by sourcing, interviewing, and onboarding new engineers
