Familiarity with frameworks such as React or Angular, backend systems like Node.js or Django, version control (Git), and basic database management is typically expected. Strong problem-solving skills, eagerness to learn, and effective communication help interns stand out in fast-paced development teams. These skills and qualities are essential for contributing to real-world projects, collaborating effectively, and accelerating professional growth in a technical environment.

Interns often assist with integrating APIs, database management, and testing features in both development and production environments. You'll likely collaborate closely with designers, product managers, and other developers, gaining exposure to the complete software development lifecycle. This hands-on experience is designed to help you build practical skills and contribute meaningful code to real applications.

Job description

Sincere is looking for a Senior Full Stack Engineer to help us make our products meaningfully better. This is a high-ownership individual contributor role for a seasoned engineer who can take a broad product area, understand the customer and business needs, and ship high-quality improvements.

You will:

  • Build full-stack features across Ruby on Rails and Next.js
  • Own product initiatives end-to-end, from identifying opportunities and shaping solutions through implementation, launch, and iteration
  • Partner with product/project managers and designers to identify customer pain points, uncover product opportunities, and deliver meaningful improvements
  • Use tools like Claude Code and Codex as a core part of your workflow to explore, develop, test, and ship
  • Make practical technical decisions that balance speed, quality, maintainability, performance, and customer impact
  • Build polished, reliable, easy-to-use experiences with strong attention to UX
  • Use tools like Datadog and Mixpanel to monitor production behavior, investigate issues, and inform product decisions
  • Champion new ideas and continuously look for ways to improve our products, engineering practices, and customer experience

You are:

  • A seasoned full-stack engineer with 7+ years of professional software development experience
  • Comfortable working across our stack, including Ruby on Rails, TypeScript, React, Next.js, MySQL/Postgres, Redis, MongoDB, Sidekiq, OpenSearch, AWS, and Docker
  • Fluent with AI-assisted development tools such as Claude Code or Codex
  • Proven at building and maintaining large-scale customer-facing web applications
  • Product-minded, with strong instincts for customer needs, UX quality, business value, and technical tradeoffs
  • A self-starter who brings structure to loosely defined problems and drives them through execution
  • A strong partner to DevOps, with enough understanding of system architecture, cloud infrastructure (AWS), deployment, containerization, and infrastructure-as-code (Terraform) to collaborate effectively
  • Skilled at working in mature codebases, understanding existing architecture, and improving systems pragmatically
  • Detail-oriented, with high standards for both the code and the customer experience
  • Entrepreneurial, curious, and biased toward building, experimenting, and shipping
  • Collaborative and low-ego, with strong communication skills and pride in your craft
