Full-Stack Software Engineer

12 of the top 15 pharma generic companies in the world trust Leucine to manufacture the drugs that reach millions of patients every day. Pharma manufacturing is one of the last large industries still running on paper, Excel, and tribal knowledge. A single missed step in a batch record can mean a recall, a regulatory warning, or a drug that should never have left the plant. Leucine is the AI platform replacing all of it. Series A, backed by top-tier global investors, 60+ pharma enterprises in production, and the team that's going to define this category. Our platform helps pharmaceutical manufacturers digitize cleaning validation and monitoring, ensuring manufacturing equipment is cleaned correctly between production runs to prevent cross-contamination. Built for QA and Validation teams, every feature we ship is designed with accuracy, traceability, and regulatory compliance at its core. We're looking for a Full-Stack Engineer who enjoys owning features end to end—from database design to APIs to user interfaces. You'll work on a modern TypeScript stack alongside engineers who value clean code, thoughtful reviews, and comprehensive testing. What you'll do

• Build full-stack features end to end—from Postgres schema design and queries to Node.js/Express APIs and React front-end development.
• Develop functionality across master data, assessments, calculations, and reporting modules.
• Write unit and integration tests as a core part of the development process.
• Translate product requirements into clean, scalable, and maintainable code while taking ownership of the features you build.

Requirements What we're looking for

• 2–3 years of experience building web apps end to end (backend + frontend)
• Strong JavaScript; TypeScript (or a clear ability to pick it up fast)
• Solid Node.js / Express (or a comparable backend framework)
• Strong SQL—writing and optimizing queries, joins, indexing, and data modeling (PostgreSQL is a plus)
• React (or a similar modern frontend framework)
• A real habit of testing your own work before it ships

Nice to have

• PostgreSQL, query tuning, TypeORM / raw SQL, and Redis
• Experience in regulated or audit-heavy domains (pharma, finance, healthcare, or government)
• Experience with .NET or Java is totally fine—concepts carry over, and we'll support the ramp-up.

Benefits

• Be part of a fast-growing SaaS company transforming the future of pharmaceutical manufacturing through cutting-edge technology
• Collaborate with a passionate, high-performing team building innovative AI-powered digital solutions
• Take ownership of impactful client implementations from day one, with ample opportunities for learning, career growth, and professional development
• Enjoy a competitive compensation package designed to reward your contributions
• Comprehensive Health Insurance with industry-leading coverage for your peace of mind
• Complimentary Meals & Refreshments: Stay energized with unlimited breakfast, lunch, snacks, and dinner provided at the office
• Family-Friendly Leave Policies, including Paternity Leave and Compassionate Leave, to support you through life's important moments
