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, 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 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

A World-Changing Company Palantir builds the world’s leading software for data-driven decisions and operations. By bringing the right data to the people who need it, our platforms empower our partners to develop lifesaving drugs, forecast supply chain disruptions, locate missing children, and more. The Role We've been doing a lot of thinking as a team, and what we've landed on is that this person needs to be someone who takes ownership. Real ownership. Not just "I'll close the ticket", but "I'm going to make sure this never happens again" type of ownership. That's the kind of person we're looking for, and frankly, that's the kind of person who's going to thrive here at Palantir. As an IT Support Engineer, you take real pride of our internal ecosystem, from individual workstations to conference rooms to the systems employees rely on every day. You're the person people turn to when something isn't working, whether they're at their desk, traveling, or preparing for an important meeting. You're thorough when it comes to troubleshooting. You don't just close the ticket, you make sure the underlying issue is actually resolved. When something keeps coming back, you dig into why and strive to look for a permanent fix. You're proactive by nature and complacency isn't something you settle for, and it’s not something we settle for either. You're constantly looking for ways to eliminate friction, automate the mundane, and elevate the bar for TechOps. People feel comfortable coming to you with problems because you're approachable and follow through. You're familiar with the needs of executives and senior staff, and you check in proactively when you know something critical is on the horizon like a board meeting, an earnings call, an internal conference or a big reveal rather than taking a back seat. What sets you apart is how much you care about the growth of the people around you. When you work through a tough ticket with a colleague, you make it a teaching moment. Whe
