Full Stack Software Engineer

Rainesdev
New York, NY

We’re seeking a highly skilled Full Stack Engineer with the mindset and drive of a founder to help us redefine how financial services are delivered. This role offers the chance to build innovative products from the ground up, leveraging cutting-edge technologies to create seamless, user-friendly digital experiences.

This position is ideal for someone who thrives in startup environments, enjoys tackling challenges head-on, and takes pride in building high-quality, impactful solutions. Whether you’re based in NYC or prefer remote work within the U.S., you’ll be joining a team that values versatility, innovation, and the ability to execute at a high level.

What You’ll Do

  • Design and Build from Scratch : Develop new products end-to-end, including both front-end interfaces and back-end infrastructure.
  • API Integration : Work with third-party APIs to add features and enhance functionality seamlessly.
  • Full Stack Development : Dive into our stack—TypeScript, React, Python (FastAPI), Postgres, and AWS—to deliver scalable, efficient solutions.
  • Collaborate and Innovate : Work closely with the team to brainstorm ideas, solve problems creatively, and ensure products align with user needs.
  • Drive Product Quality : Prioritize building robust, reliable systems that customers love using.
  • Shape the Future : Contribute to the evolution of our technology and help establish best practices for scaling the team and platform.

What We’re Looking For

We’re looking for someone with the skills and mindset to thrive in a fast-paced, entrepreneurial environment. Ideal candidates will have:

  • Experience in Full Stack Development : Comfortable working across front-end and back-end technologies, with proficiency in TypeScript, React, Python, Postgres, and AWS.
  • Startup Background : Proven success in early-stage or growth-stage startups (under 200 employees), with rapid promotions or significant project leadership experience.
  • API Expertise : Experience building against third-party APIs and integrating them into new or existing systems.
  • Strong Technical Foundation : A degree in Computer Science from a top-tier institution (e.g., Ivy League, Stanford, MIT, UC Berkeley, CMU, Waterloo).
  • Proven Builder : Demonstrated ability to create and launch products from scratch, both on the front end and back end.

Bonus Points

  • Founder Mindset : Previous experience as a founder or founding engineer, showcasing your ability to take initiative and build something from nothing.
  • Side Projects : A history of personal projects that demonstrate your curiosity, ambition, and passion for building.

Why This Role?

You’ll be joining a team that believes in delivering maximum value to customers through exceptional digital experiences. We’re focused on creating products that are scalable, efficient, and game-changing in their impact. If you’re looking to work on meaningful projects, solve complex problems, and make a difference, this is the opportunity for you.
