Raydar is recruiting for this role on behalf of our client. Own a specialized engineering domain within a software platform, pairing hands-on development with deep technical design knowledge. The work spans shaping product direction, setting quality standards for automated outputs, reviewing results and supporting early external users.

What you'll do

• Build and maintain domain-specific content libraries on top of a core software engine, converting specialist knowledge into clear acceptance criteria.
• Drive product thinking for your area, defining what strong tooling should look like and spotting gaps in the current strategy.
• Review automated design outputs for quality, confirming they satisfy professional standards and practical needs.
• Spend a few hours each week with external collaborators, learning how they work, seeding initial content and helping new users get started.
• Write production code in Python and TypeScript to deliver platform features, using AI coding assistants to move quickly.

• Proficiency in Python or TypeScript.
• A bachelor's or master's degree in mechanical engineering, computer science, physics or computational design from a highly ranked university.
• Self-direction and a habit of proposing your own product ideas rather than waiting for tasks.
• Comfort with occasional customer-facing conversations.
• Ability to work on-site five days per week.

Bonus points

• Experience creating internal automation or computational design tools at an engineering or construction firm.
• Academic grounding in both a physical science or engineering discipline and computing.
