Join our Haskellers team at Stack Builders! We're looking for an experienced functional programming engineer to support a long-term project that is almost entirely built in Haskell. This is a staff augmentation role where you'll contribute to the development and optimization of a mission-critical application with high scalability and data integrity requirements.

Innovation is at the heart of Stack Builders. Our cross-cultural development team pushes the boundaries of functional programming by building applications that consistently exceed expectations, while adhering to best practices in communication, teamwork, and continuous improvement.

We're seeking a part-time remote contractor (20-30 hours per week) with strong Haskell expertise and the ability to collaborate on database and infrastructure enhancements. This role requires a proactive professional who thrives in fast-paced environments and takes pride in delivering robust, high-quality code.

Requirements

  • Advanced English (spoken and written). You will be directly communicating with the client
  • Must be able to work as an independent contractor. For candidates based in the US, an LLC, S-Corp, or C-Corp structure is required
  • 5+ years of professional Haskell experience with outstanding programming skills
  • Strong experience with Yesod and database-related libraries (Persistent, Esqueleto)
  • Solid background in writing clean, testable, and scalable code
  • Experience applying property-based testing
  • Strong collaboration and problem-solving skills with excellent verbal and written communication
  • Availability to work 20-30 hours per week and overlap 4 hours with EDT
  • Bonus: Frontend experience with TypeScript/React

Responsibilities

  • Architect and build backend solutions in Haskell (95% of work)
  • Implement and optimize database operations (Persistent, Esqueleto)
  • Collaborate on infrastructure enhancements to ensure scalability and performance
  • Contribute to code quality practices, including property-based testing (QuickCheck, related libraries)
  • Occasionally collaborate on frontend components with TypeScript (e.g., React, jQuery, Bootstrap, Webpack)
  • Participate in agile rituals: stand-ups, sprint planning, retrospectives
  • Engage directly with the client during rituals, providing updates, gathering requirements, and ensuring alignment with their needs

The projected hourly range for this position is from $47.00 to $57.00/ hour, determined by the candidate's interview outcome, skills, experience, education, and alignment with market data.

Benefits

  • 100% remote work modality
  • A human-centered experience, as we're a people-first company
  • Challenging, exciting and long-term projects. We work with some of the most admired companies worldwide
  • A strong learning culture. You'll have opportunities for 1:1 sessions with your manager

  • Opportunities for company-sponsored conference participation, OSS contributions, tutorials, blog posts, and technical talks
  • Exceptionally talented and passionate coworkers
