Senior Backend Engineer (L5) - Core trading

About Us OpenFX is on a mission to move money as freely as data, unrestricted by time zones, banking hours, or legacy systems. We are building the infrastructure that will power the next generation of cross-border payment systems for institutions. The team's execution has been exceptional, and we're scaling at a remarkable pace. Our stellar early team comes with experience in companies like J.P. Morgan, Goldman Sachs, FalconX, PayPal, Affirm, Polygon, Kraken, Nium & others. We're backed by Accel, Lightspeed, NfX and other top-tier investors. Role Overview We're hiring a Staff Software Engineer for our Payments team. This is the senior-most individual contributor role on the systems that move money across borders — payment orchestration, corridor and partner integrations, FX and quoting, the payment lifecycle from initiation to settlement confirmation, and the regulated controls (safeguarding, transaction monitoring) that our EU licenses demand. It is a hands-on technical leadership role on the money path, where a new corridor is only as good as its failure handling, and a regulatory control is only as good as the evidence it produces. The cost of a defect is measured in real money, stuck customer payments, or a finding from a regulator. You will report to an Engineering Manager and work closely with engineers, product, compliance, and partnerships across the company. You will set the technical direction for payments, lead the hardest corridor and orchestration problems, and raise the bar for how we build. This role requires someone who has built and operated payment or other correctness-critical systems in production, ideally against external partners whose behavior you do not control. If your experience is limited to systems where occasional data inconsistency is acceptable, where every dependency was internal and well-behaved, or where you have not owned something end to end for a meaningful stretch, this will be a stretch. Key Responsibilities Own the technic

Role Overview We're hiring a Staff Software Engineer, Frontend for our Banking team. This is the senior-most individual contributor role for the banking user experience and the frontend platform behind it — onboarding, banking product screens, and the unification of banking and payments, along with the SDK and shared foundations that let those experiences be built quickly and integrated externally. You will report to an Engineering Manager and work closely with engineers, product, and design. You will set the standard for how frontend is built across the platform, lead the hardest frontend problems, and make other teams faster. This role requires someone who has built frontend as a platform, not just individual product screens. If your experience is limited to single-product frontends without reuse, consistency, or SDK thinking, this will be a stretch. Key Responsibilities Own the frontend technical direction for banking: onboarding, the unified banking and payments experience, and banking product surfaces. Design and build a Banking frontend SDK - hooks and UI components - packaged for external integration, with documentation and framework integrations. Shape the shared component library and a micro-frontend approach that keep product surfaces consistent. Define frontend coding and component standards across the platform. Own the frontend observability and test-automation bar so regressions are caught before customers feel

Role Overview We're hiring a Senior Backend Engineer for our Hedging team — the team that owns the risk OpenFX carries. Hedging owns inventory and exposure management, risk management, hedging positions across venues through smart routing strategies, market making, Cost, PnL and net revenue calculation. Every trade a client places creates exposure, and this team decides what we hold, what we hedge, where we hedge it, and what it costs us. You will own significant parts of the Risk Management Engine and Smart Hedging end-to-end — design, build, ship, and operate. This is a hands-on senior IC role with high ownership and accountability - the routing and exposure logic you write today shows up in tomorrow's net revenue. We're specifically looking for someone with a trading background — you've built systems where a position had to be accurate and a hedge had to fire in time, and where a bug meant real money. Think a crypto exchange, brokerage, or trading platform (CoinDCX, Groww, CoinSwitch Kuber, or similar). Key Responsibilities Design, build, and operate services across the risk path — inventory and exposure tracking, hedge decisioning, venue routing, and WAC / PnL / net revenue calculation. Own features end-to-end: scoping, technical design, delivery, rollout, and the operational health of what you ship. Drive work to closure with Product, Design, and Operations. You are accountable for adoption, not just delivery. Act as a

Role Overview We're hiring a Senior Backend Engineer for our Trading team — the team that owns the client's entire trade experience. Trading owns quote generation, pricing strategy, the spread engine, and the trade lifecycle across GUI, API, and soon conversational AI. Our north star is Total Payment Volume, with Gross Revenue as the control metric. Every trade a client places moves through the systems this team builds. You will own significant parts of the Client Trading Engine and Pricing Engine end-to-end — design, build, ship, and operate. This is a hands-on senior IC role with high ownership and accountability - the pricing logic you write today shows up in tomorrow's revenue numbers. We're specifically looking for someone with a trading background — you've built systems where a quote had to be correct and fast, and where a bug meant real money. Think a crypto exchange, brokerage, or trading platform (CoinDCX, Groww, CoinSwitch Kuber, or similar). Key Responsibilities Design, build, and operate services across the trade path — quoting, pricing, spread application, and trade lifecycle management. Own features end-to-end: scoping, technical design, delivery, rollout, and the operational health of what you ship. Drive work to closure with Product, Design, and Operations. You are accountable for adoption, not just delivery. Act as a product engineer — scope a problem statement, understand its product impact, and take the ha

Role Overview We're hiring a Tech Lead for our Hedging team — the team that owns the risk OpenFX carries. Hedging owns inventory and exposure management, risk management, hedging positions across venues through smart routing strategies, market making, Cost, PnL and net revenue calculation. Every trade a client places creates exposure, and this team decides what we hold, what we hedge, where we hedge it, and what it costs us. This is a hands-on technical leadership role, not a management role. You will not own headcount, performance reviews, or hiring decisions. What you own is the technical direction, quality bar, and execution coherence of the Hedging team's work — the Risk Management Engine, Smart Hedging, and the position and PnL layer underneath them. You and the Engineering Manager operate as a closely coordinated pair: the EM owns the people, the process, and the delivery plan; you own how the work is designed, how quality is held, and how technical decisions get made day to day. You should expect to write code. The strongest Team Leads here lead through design, review and judgment, but their credibility comes from building.
