Requirements and responsibilities
About UsAt Benepass we're making benefits easy. We believe people are the most important asset to any company. Traditional one-size-fits-all benefits packages no longer cut it in today's hybrid and remote-first environment. With Benepass, companies can tailor their benefits to the unique needs of their workforce.Through our easy-to-use and highly customizable fintech platform, People teams can implement, administer, and track the benefits that meet employees where they are. Employers design their benefits and perks plan by setting a contribution amount and eligible spend categories. Every employee has their own individual definition of wellness and needs different things to help them be their most productive, fulfilled self.Our MissionHelping companies reimagine how companies take care of their people.Our InvestorsWe are backed by leading investors, including Centana Growth Partners, Portage Ventures, Threshold Ventures, Gradient Ventures, Workday Ventures, and Clocktower Technology Ventures. To date, the company has raised approximately $75 million in equity capital.TEAM & ROLEBenepass 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 willDesign 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 transactionsBuild systems that are correct by design:Define and always maintain invariants to ensure correctness under all operational conditionsIdempotentStrongly consistent where requiredFully auditableOwn the lifecycle of financial transactions end-to-end, including:State transitionsFailure handling and retriesReconciliation and reportingIntegrate with external financial partners (processors, banks, networks) and handle unreliable and asynchronous dependenciesLead architectural decisions and write technical approach documents that clarify trade-offs and long-term implicationsImprove system resilience, observability, and operational tooling as volume and complexity growMentor other engineers and help define best practices for building financial systemsOUR TECHNOLOGY AND STACKPython, Django, Django Rest Framework, PostgreSQL, AWS, Docker, React, TypeScriptREQUIREMENTSExperience building or operating financial systems such as payments, card issuing, wallets, or banking infrastructureDeep understanding of fintech and payments ecosystems, including:Card network fundamentals (e.g., ISO 8583 messaging, authorization/clearing/settlement flows)Merchant acquiring and payment processor flowsHow issuers, sponsor banks, and processor integrations work in practiceFamiliarity with real-world transaction lifecycles across the stack (network → processor → ledger)Experience designing or working on a ledger system, including:Double-entry accounting conceptsTransaction lifecyclesBalance correctness and reconciliationExperience building decisioning systems in production (e.g., transaction authorization, rules engines), ideally in real-time or latency-sensitive contextsExperience working on systems that handle real money at scale (thousands of transactions per day or more)Experience with global money movement, including:Multi-currency systemsCurrency conversion or FX considerationsCross-border transactions (nice to have but strongly preferred)Strong understanding of:Data consistency and correctnessIdempotency and safe retriesFailure modes in distributed systemsExperience integrating with external financial APIs, including handling partial failures, timeouts, and eventual consistencyProficiency in Python and relational databases (PostgreSQL preferred)ABOUT YOUYou think in systems, not endpointsYou don’t just build APIs — you design systems that model real-world financial behavior. You understand how money moves through a system, how state changes over time, and how to ensure that state remains correct under failure.You optimize for correctness firstYou prioritize:Accurate balances over eventual fixesClear invariants over implicit assumptionsSystems that are easy to reason about under stressYou’ve seen what goes wrong in financial systems — and you design to prevent it.You are comfortable with complexityYou’ve worked on systems with:Multiple sources of truth (and resolved them)Asynchronous workflows and external dependenciesSubtle edge cases (duplicates, race conditions, reconciliation gaps)And you know how to simplify where it matters.You take ownership of critical infrastructureYou are comfortable owning systems where:Failures are visible and impactfulDebugging requires tracing through distributed systemsLong-term maintainability matters as much as short-term deliveryYou raise the bar for the teamYou write clear design docs and communicate trade-offs effectivelyYou mentor other engineers in system design and domain understandingYou push for better patterns, better abstractions, and better systemsThis role is NOT a fit if:You’ve primarily worked on CRUD-style backend systems without ownership of data integrity or system correctnessYou prefer loosely defined systems where eventual consistency and approximation are acceptableYou have not worked with systems that move or track real moneyCOMPENSATIONBase salary of $200,000 to $240,000 + equity.Range(s) is subject to change.
