Staff Software Engineer – Payments & Ledger

About the Role

Take Command is building the financial foundation for a better health insurance experience. As more employers use our platform to reimburse employees for individual insurance, how money moves through our system becomes critical to making that experience affordable, reliable, and easy to understand.

We’re looking for a Staff Engineer with real experience building ledger, payments, card, reimbursement, or money movement systems in production.

This is a senior role with meaningful influence over the technical and product direction of our financial systems. You’ll help us make sound architectural decisions, avoid common pitfalls in financial system design, and raise the team’s understanding of proven ledger and payment patterns.

The role is full-stack, but heavily backend-leaning. Most of your work will be in Java, Postgres, and AWS, with occasional React work where needed. Over time, we expect more of our stack to move toward TypeScript, and you’ll have an opportunity to help shape that transition.

What You'll Do

• Drive architecture and implementation for ledger, payments, and money movement capabilities, both through your own contributions and by guiding technical decisions across the team
• Design systems that handle financial events, balances, reimbursements, payment states, reconciliation, reversals, and related workflows
• Build reliable backend services, integrations, and data models for systems where correctness matters
• Partner with product and engineering leaders to shape the direction of our financial platform
• Bring practical experience from production financial systems to help us avoid common mistakes and choose proven patterns
• Mentor other engineers and help establish strong engineering patterns for financial systems
• This role doesn’t require people management, but the opportunity does exist

What We're Looking For

• Significant experience building and operating production financial systems
• Hands-on experience with ledgers, payment systems, card payments, banking integrations, reimbursements, or similar money movement infrastructure
• Strong backend engineering experience, ideally with Java or a similar language
• Strong relational database experience, especially with data models that require accuracy, traceability, and long-term maintainability
• Ability to lead through technical judgment, clear communication, mentorship, and execution
• Comfort working through ambiguous product and technical problems
• A product-minded approach to engineering, with an interest in how technical decisions affect customers, operations, and the business
• Pragmatic judgment about when to invest deeply, when to keep things simple, and how to make tradeoffs without losing sight of financial integrity

Compensation

• $165,000 - $235,000 + 10% bonus
• We believe employees should be compensated fairly based on the market in which they live and work. Using geographic market data helps us maintain competitive pay, support internal equity, and ensure a consistent approach to compensation decisions across the company.
