Software Engineer

About the Role

We're looking for a Software Engineer to join our product team and help build the features that power the financial operating system of the future. This is a hands-on engineering role where you'll create new features, maintain and evolve existing ones, and help shape the architectures that support our product as it scales.

We care a lot about writing code that scales and can be reused across the entire organization — not just shipped once and forgotten. You'll work in a fast-moving environment with multiple projects running in parallel. In the near term, you'll need to be flexible, jumping onto whatever feature or topic the team needs most. Over time, as the engineering organization grows, you'll become part of a team that owns a specific product or product line.

If you're someone who wants to grow, take on more ownership, sharpen your craft, and have real impact on a product that allows other engineers across the world build more efficiently this is a great opportunity for you.

What You'll Do

• Build product features that help manage half a billion dollars of annual spend and save customers millions of dollars per month
• Design, build, and maintain Python micro-services that power core product functionality
• Handle data efficiently at runtime, making thoughtful decisions about performance, memory, and latency
• Build well-structured service layers, libraries, and abstractions that other teams can reuse across the organization
• Propose architectures and solutions for new features, not just implement specs
• Think about the future needs of a feature — design today in a way that doesn't paint us into a corner tomorrow
• Write strong tests and set up the right guardrails so development moves fast without breaking things
• Maintain and improve existing systems, refactoring where needed as product requirements evolve
• Collaborate closely with your product, platform, and AI/ML team. Jump across the stack and across product areas as priorities shift, especially in the first year.

What We're Looking For

• 4-10 years of software engineering experience building and shipping production systems
• Strong Python experience, with a solid grasp of libraries, service layers, object handling, and writing clean, idiomatic code
• Strong fundamentals around code versioning (Git workflows, branching strategies, code review) and collaborative development
• Experience designing and operating micro-services in production
• Ability to write code that scales and can be reused across the organization — you think about interfaces and abstractions, not just one-off implementations
• Solid understanding of how to model and handle data efficiently at runtime, including memory, throughput, and latency tradeoffs
• Strong critical thinking skills — you reason from first principles, weigh tradeoffs honestly, and can defend your design decisions
• Pragmatic use of LLM code gen tools: you use them to move faster, but you still understand the code, the principles behind it, and the tradeoffs being made
• Self-awareness and a growth mindset: you learn from your mistakes, take feedback well, and get better with every project
• Ability to propose architectures and solutions, not just execute on tickets, you can think a feature through end to end
• Strong testing discipline, a belief that good tests make teams faster, not slower
• Comfort operating in a fast-moving environment
• Strong communication skills

Nice to Have

• Outstanding recognition in competitions, awards, or business ventures
• Experience in a startup or fast-moving environment
• Familiarity with FinOps concepts or financial data
• Experience owning a product or product line end to end
• Built systems that scaled rapidly with user growth
