About the role

Senior Fullstack Software Engineer

Location: Soho, NYC / Hybrid (an in-person interview may be required) Department: Engineering

The Role

We’re looking for a Senior Fullstack Software Engineer to help architect, build, and scale the next generation of our Flowcode 2 platform and consumer experiences. You will join our engineering team with a focus on creating amazing end user hub and landing page experiences that are dynamic and engaging, as well as the platform and management capabilities for creators on the platform. You’ll work across the stack — from contributing to backend services to building out dynamic end to end landing pages. Though this is a full stack position, we are looking for someone that has deep backend experience as well.

As one of the senior engineers on a small but highly capable team, you’ll own medium to large sized features, drive technical execution, contribute to a delivery focused environment, and mentor others. You’ll balance hands-on engineering with architectural thinking, helping us move fast while maintaining reliability, performance, and code quality.

This is an ideal role for a problem-solver who values simplicity over complexity, enjoys building dynamic and interactive applications and approaches engineering with pragmatism and curiosity.

What You’ll Do

- Design, build, and maintain scalable features across a modern front-end framework and backend services.

- With support, own key features end-to-end, from data design to user-facing experiences.

- Architect for growth — help drive your pods’s technical roadmap and shepherd established engineering best practices.

- Collaborate across teams with product, design, and data to deliver measure, deliver and grows features quickly and iteratively.

- Write clean, reliable, and maintainable code, with strong attention to performance, best practices and developer experience.

- Mentor engineers and help elevate technical execution across you pod.

- Stay pragmatic — balance ideal engineering with the realities of speed, customer needs, and startup resource constraints.

What We’re Looking For

- 5–7+ years of experience building and shipping production-quality software across the stack.

- Proficiency in at least one modern backend language (e.g., Go, Python, C#, Java).

- Strong experience with React, Next.js, or other modern front-end frameworks. We use Svelte but any modern framework experience is welcome.

- Deep understanding of web architecture, API design, and data modeling in relational and/or NoSQL databases.

- Familiarity with cloud environments (AWS, GCP, or similar) and containerized deployment (Docker, Kubernetes).

- Commitment to code quality, with solid grounding in design patterns, testing, and CI/CD.

- Strong grasp of scalability and performance — able to make informed tradeoffs between speed and correctness.
