Requirements

Functional Programming Engineer
(Haskell / PureScript — training provided)

About the Role

This is not a typical fullstack role.

You’ll be working on a core engineering team building optimization software for the freight/logistics industry, where the complexity lies not in the framework — but in how problems are modeled and solved.

We care far more about how you think than the specific languages you’ve used.

If you’re comfortable with concepts like immutability, pure functions, composition, and enjoy solving non-trivial problems (concurrency, data consistency, system behavior) — this role is for you.

You don’t need prior Haskell experience. However, this is not a beginner-friendly role
we’re looking for engineers with strong fundamentals who can quickly adapt to a functional programming paradigm.

The CTO will support your transition into Haskell.

What You’ll Do

• Build and maintain systems using Haskell (backend) and PureScript (frontend) — with onboarding support
• Work daily in pair programming and participate in code reviews
• Solve problems involving:
• Concurrency
• State management
• Data consistency and transactions
• Contribute to a system that prioritizes correctness, reliability, and maintainability
• Work in fully Dockerized environments (development and execution)

What We’re Looking For

Must-have

• Strong foundation in JavaScript (vanilla ES5/ES6) — not just frameworks
• Solid understanding of functional programming principles:
• Immutability
• Pure functions
• Composition
• Strong computer science fundamentals:
• Concurrency
• Data structures
• Transaction handling (locks, consistency models, etc.)
• Hands-on experience with Docker and Docker Compose
• Ability to work across frontend and backend contexts
• Comfortable working in collaborative environments (pair programming, code reviews)
• Functional English (written and spoken)

Nice to have

• Experience with functional or strongly-typed languages:
• Haskell, PureScript, Scala, F#, Elixir, Clojure
• Experience with test-driven development (TDD)
• Exposure to distributed systems or microservices
• Familiarity with AWS (not required)

What You Don’t Need

• Prior experience with Haskell or PureScript
• Background in AI / Machine Learning
• Experience managing cloud infrastructure
• Domain knowledge in logistics

How We Work

• Pair programming is part of the daily workflow
• Code quality and correctness matter more than speed
• Limited use of AI tools due to IP and legal constraints (GitHub Copilot allowed only for PR reviews)

Who This Role Is NOT For

• Engineers focused primarily on frontend frameworks without strong JavaScript fundamentals
• Developers who rely heavily on frameworks rather than core programming concepts
• Engineers without exposure to backend or system-level thinking
• Candidates who depend heavily on AI tools to write code
• Profiles focused on DevOps, SRE, Data Science, or AI/ML

Why Join

• Work directly with a highly technical CTO and learn Haskell in production
• Be part of a core engineering team (6 hires) shaping the system
• Solve technically meaningful problems, not just features
• Grow into functional programming in a real-world environment
