Senior Full Stack Engineer (Innovation & Prototyping) - 26052001

Our client is a fast-growing technology company building internal AI-powered products for industries including railroads, manufacturing, energy, and insurance. They work with enterprise customers across the US and are building a distributed product engineering organization across the US, India, and Eastern Europe.

We’re looking for a Senior Full Stack Engineer who loves building, experimenting, and solving ambiguous problems. This is not a traditional delivery-focused engineering role. It’s a high-autonomy position centered around rapid prototyping, product innovation, and AI-assisted development.

You’ll take high-level concepts and quickly turn them into interactive demos, working prototypes, and scalable technical foundations. You’ll collaborate closely with product, design, and engineering leadership to explore new ideas, validate user experiences, and shape how our products evolve.

This role is ideal for engineers who enjoy starting things, moving quickly, and iterating with feedback — without spending months inside rigid delivery cycles.

What You’ll Do

• Build end-to-end prototypes and product experiences across frontend and backend

• Rapidly turn high-level concepts, user goals, and lightweight requirements into working software

• Explore new interaction patterns and innovative UI experiences

• Prototype quickly, gather feedback, iterate, and refine

• Translate experimental ideas into scalable technical approaches

• Use AI-assisted engineering tools to accelerate development workflows

• Work closely with product managers, designers, architects, and engineering leadership

• Help shape product direction through technical and UX recommendations

• Create the initial 10–30% of implementation and architecture before handing projects to the broader engineering team for full-scale delivery

• Balance speed, usability, scalability, and technical quality

How This Role Works

This role operates inside a rapid innovation cycle.

You’ll receive:

• high-level product concepts,

• user goals,

• design direction,

• and problem statements.

From there, you’ll independently:

• explore solutions,

• prototype ideas,

• suggest approaches,

• and demonstrate working concepts quickly.

We value rapid experimentation, fast feedback loops, and practical problem solving over excessive process or long specification cycles.

Once concepts are validated, the broader engineering organization takes over long-term implementation and scaling.

Our Core Tech Stack

Frontend

• React

• TypeScript

• Vite

• Storybook

Backend & APIs

• .NET Minimal APIs

• Node.js / Express

• REST APIs

• gRPC

Testing

• Playwright

• Vitest

AI-Assisted Engineering

• GitHub Copilot

• AI-powered development workflows

• Rapid prototyping with generative AI tools

What We’re Looking For

• 5+ years of full stack engineering experience

• Strong experience with React and TypeScript

• Experience building modern APIs and scalable web applications

• Comfortable working with ambiguity and incomplete requirements

• Strong product thinking and user-focused problem solving

• Ability to move quickly while maintaining practical engineering quality

• Experience using AI coding assistants and AI-assisted development workflows

• Self-directed mindset with strong ownership and initiative

• Comfortable making technical decisions independently and proposing solutions proactively

• Strong communication and collaboration skills in remote environments

Strong Backgrounds Include

• Product companies

• Startup environments

• Digital agencies

• Technology consulting firms

• Innovation-focused engineering teams

Especially engineers who are used to:

• rapid iteration,

• prototyping,

• client or product ambiguity,

• and balancing speed with practicality.

What Success Looks Like

• Product ideas quickly become interactive demos and working prototypes

• User feedback loops happen rapidly

• New concepts move efficiently from experimentation into scalable implementation

• Engineering and product teams gain confidence in technical direction faster

• Innovation cycles stay fast, practical, and user-focused

Why This Role Is Interesting

• High autonomy and ownership

• Constant variety of technical and product challenges

• Opportunity to shape product direction early

• AI-native engineering environment

• Fast-moving startup culture

• Focus on innovation and creation instead of long delivery cycles

• Collaborative international engineering organization across the US, India, and Eastern Europe
