Senior TypeScript Developer (Backend / Full-Stack)

We’re looking for someone who is AI-native. You’ve integrated LLMs into your daily workflow — for coding, documentation, learning, and thinking through problems. But it goes beyond personal productivity: you’re excited about building AI-powered features into products. Natural language interfaces. Assistants that reduce cognitive load for users. You understand that AI is a tool with sharp edges — you know its failure modes, you validate its outputs, and you can teach others to use it effectively.

About the role:

• Own the architecture of MGP UI — make foundational decisions on stack, patterns, and boundaries that will scale with the product.

• Write production TypeScript — backend services, APIs, and full-stack features when needed.

• Establish engineering practices — code review culture, testing strategies, CI/CD standards, documentation norms.

• Integrate AI into workflows — both internal tooling and product features.

• Mentor engineers, conduct design reviews, and raise the technical bar across the team.

• Collaborate cross-functionally with product, data, and platform teams.

Requirements:

• 5+ years of experience in software engineering.

• Deep TypeScript expertise — generics, conditional types, mapped types, type inference, type-safe API design.

• Backend architecture experience — scalable services, distributed systems, PostgreSQL, message queues, caching.

• AI fluency — you actively use Claude, GPT, Copilot, or similar tools in your daily work and can articulate where AI helps and where it fails.

• Strong communication — clear RFCs, constructive code reviews, ability to explain decisions to non-technical stakeholders.

Nice to Have

• Experience with React / Next.js for full-stack work.

• UI/UX sensibility — you care about how interfaces feel, not just how they function. Experience with design systems, accessibility, or working closely with designers is a plus.

• Familiarity with ad tech domain (RTB, programmatic, exchange mechanics).

• Contributions to open-source TypeScript libraries or tooling.

• Interest in functional programming patterns applied to TypeScript.

With a powerful product, strong market positioning, and a team that strives for excellence, BidMachine offers a unique opportunity to grow, innovate, and make a tangible impact in the programmatic advertising space.
