• Collaborate with teams across app integrations, product, and design.
• Work in a high-trust environment with product ownership and autonomy.

Qualifications

• Experience with distributed systems and data pipelines.
• Think in systems and care about correctness, reliability, and performance.
• Enjoy solving real customer problems and delivering outcomes.
• Balance engineering quality with product delivery.
• Take initiative and ownership of complex projects.
• Comfortable analyzing trade-offs and making empathetic decisions.

Benefits

• Join an experienced and passionate team of functional developers.
• Significant autonomy in a high-impact, product-focused engineering culture.
• The opportunity to contribute to an advanced Haskell system, in production today.
• The ability to shape how customers connect their business tools in a rapidly growing space.
