Job Description

We’re looking for a Senior who thrives in high-growth environments and has a strong track record of building and scaling products from scratch. You’ll play a key role in shaping our engineering practices, influencing architectural decisions, and driving product execution. This role is ideal for someone who is deeply technical, hands-on, and excited to build from zero to one.

What You’ll Do

  • Design, develop, and maintain scalable, performant, and secure full stack web applications.
  • Build intuitive, responsive, and elegant user interfaces with modern web technologies.
  • Architect and implement robust backend services and APIs in a cloud-native environment.
  • Collaborate closely with cross-functional teams to deliver business-critical features that move the needle.
  • Thrive in ambiguity, hustle through constraints, and deliver measurable impact on short, iterative cycles.
  • Contribute to shaping our technology stack, engineering culture, and best practices.

What We’re Looking For

  • 5+ years of professional software engineering experience, ideally with experience shipping and scaling products in Series A/B stage startups or similarly dynamic environments.
  • Proven ability to build production-grade systems from scratch in fast-paced, high-stakes settings.
  • Advanced proficiency in Next.js or React.js for modern web applications.
  • Strong backend expertise in Next.js, Node.js, TypeScript, GraphQL, and PostgreSQL (or equivalent relational databases).
  • Hands-on experience with cloud infrastructure (AWS preferred), with the ability to architect event-driven, serverless, and containerized solutions.
  • Experience building or integrating Generative AI applications into production workflows.
  • Comfort working with TailwindCSS for highly polished and responsive UI.
  • A mindset of ownership, autonomy, and growth, willing to step beyond your comfort zone and solve ambiguous problems.
  • Clear and proactive communicator, able to collaborate effectively with distributed, cross-functional teams.

Bonus Points

  • Experience in DevOps or setting up CI/CD pipelines from scratch.
  • Familiarity with Hasura, Auth0, TurboRepo, or Chrome Extension development.
  • Understanding of event-driven architectures or distributed systems design principles.
  • Prior experience mentoring or leading a small team of engineers.

Why Join Us

  • Be part of a tight-knit, high-caliber team on an early-stage rocket ship — make your mark on a product that’s redefining its category.
  • Enjoy massive ownership and autonomy from Day 1 — your decisions and execution will directly shape the company’s trajectory.
  • Work on impactful, high-visibility projects with modern technologies and innovative approaches.
  • Help build not just the product, but also the engineering culture and practices that will define our future.
