Senior Full Stack Engineer

About the company

Our client is a fast-growing software company.

The role

Raydar is recruiting for this role on behalf of our client. Act as a hands-on senior engineer who owns the customer-facing side of a web application, carrying features from first prototype through release with care for polish and speed. Work side by side with leadership and cross-functional colleagues while raising the bar for code quality and coaching other engineers.

What you'll do

• Design and build full-stack features, including refined user interfaces, dependable APIs and scalable backend services.
• Take product features from early prototype to launch, paying close attention to responsiveness, usability and visual finish.
• Collaborate with product, sales, marketing and leadership to connect third-party generative AI models through their APIs and open up new use cases.
• Translate design mockups into polished, production-ready interfaces.
• Lead large product initiatives from concept to release, including upcoming launches.
• Define coding conventions and quality practices for the team, and coach colleagues through your own example.

Requirements

What we're looking for

• 5 to 10 years of professional experience delivering full-stack web products.
• Industry experience with TypeScript and AWS, including React front ends and Node.js back ends.
• Background building full-stack systems that scale, such as data-heavy processing, search and retrieval, or background job workflows.
• At least 12 months of professional experience building LLM-based or agent-based products at a startup or AI-focused company; personal projects do not count.
• Startup experience; a career spent only at large technology companies is not a fit.
• A portfolio of shipped interfaces or products that demonstrates strong product sense and visual taste.
• Solid computer science fundamentals, including system design, algorithms and application architecture.
• A formal computer science or engineering degree.
• Fluent English for reading, writing and speaking.
• A record as a hands-on technical lead who raises standards and helps mid-level engineers grow.
• Ability to work on-site five days a week in a fast-paced startup and start in the office right away.

Bonus points

• Familiarity with working on media or video technology.
• Experience with consumer-facing generative AI products.
