TEAM & ROLE
Benepass is building financial infrastructure that powers how companies fund, control, and deliver benefits globally.
We are hiring a Senior Software Engineer to own and evolve the systems at the core of our platform: ledgering, transaction processing, decisioning, and money movement. These systems are responsible for tracking and moving real funds, enforcing complex rules, and maintaining a precise and auditable source of truth.
This is not a typical backend role. You will be working on high-integrity financial systems where correctness, consistency, and reliability matter more than raw throughput — and where small mistakes can have real financial impact.
This role is ideal for engineers who have built or operated systems in payments, card issuing, wallets, banking infrastructure, or global money movement platforms, and want to take end-to-end ownership of a growing fintech layer.
You will
Design and operate systems responsible for:
Ledgering (double-entry systems, balances, transaction history, reconciliation)
Transaction processing pipelines (authorization, capture, settlement flows)
Real-time decisioning (spend controls, eligibility, rules engines)
Money movement, including support for multi-currency and global transactions
Build systems that are correct by design:
Define and always maintain invariants to ensure correctness under all operational conditions
Idempotent
Strongly consistent where required
Fully auditable
Own the lifecycle of financial transactions end-to-end, including:
State transitions
Failure handling and retries
Reconciliation and reporting
Integrate with external financial partners (processors, banks, networks) and handle unreliable and asynchronous dependencies
Lead architectural decisions and write technical approach documents that clarify trade-offs and long-term implications
Improve system resilience, observability, and operational tooling as volume and complexity grow
Mentor other engineers and help define best practices for building financial systems
OUR TECHNOLOGY AND STACK
Python, Django, Django Rest Framework, PostgreSQL, AWS, Docker, React, TypeScript
REQUIREMENTS
Experience building or operating financial systems such as payments, card issuing, wallets, or banking infra
