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.\nRole Overview\nWe're hiring a Staff Engineer to own the architecture of OpenFX's trading and hedging core - the systems that price a client's trade, execute it, and manage the risk we take on as a result.\nTwo teams sit inside this scope:\nTrading owns the client's entire trade experience - quote generation, pricing strategy, the spread engine, and the trade lifecycle across GUI, API, and soon conversational AI. Its north star is Total Payment Volume, with Gross Revenue as the control metric.\nHedging owns inventory and exposure management, risk management, hedging across venues through smart routing, market making, and WAC / PnL / net revenue calculation.\nYou will be the senior-most individual contributor across both, responsible for the Client Trading Engine, Pricing Engine, Risk Management Engine, and Smart Hedging. This is a hands-on role. You will write code, set architectural direction, and be the person the organisation trusts to get the trade and risk path right.\nThe problems here are genuinely hard and often under-defined. You'll take large architectural bets in a domain where correctness is measured in real money and latency is measured on a live client trade.\nKey Responsibilities\nOwn the architecture of the Client Trading Engine, Pricing Engine, Risk Management Engine, and Smart Hedging.\nBreak complex, ambiguous systems into smaller components with clear contracts, clear scope, and independent deliverability.\nSet and drive the architectural vision for trading and hedging, and take large architectural bets through to completion.\nBuild for scale - design systems that hold up as volume, venues, and currency corridors grow.\nOwn the observability standard across all components, so the behaviour of the trade and risk path is legible when it matters.\nDesign meaningful alerting, fallback, and recovery strategies across systems.\nCoach and mentor engineers on the team, and raise the technical bar through design reviews and feedback.\nPartner with product, risk, and the two pod EMs to connect architectural decisions to TPV, gross revenue, and net revenue outcomes.\nWhat we are looking for\nMust-haves:\n7-12 years of experience building and operating production backend systems.\nDeep experience with distributed systems - consistency, failure modes, and the trade-offs between them.\nExperience building orchestrators and complex, long-running workflows that must be durable and recoverable.\nStrong command of databases at scale - sharding, multi-region deployments, and the data protection constraints that shape them.\nTrack record on high-scale systems, including the observability and operational tooling that keeps them healthy.\nComfort with abstract, ambiguous problems - you're the person who turns a vague mandate into scoped, sequenced deliverables.\nHands-on. You still write code, and your architectural judgment comes from building.\nHeavy AI user. You use AI coding tools with real technique and get materially more done because of it.\nInfluential and collaborative. You set direction by inspiring and persuading people, not by relying on authority.\nData-driven, and you operate with high agency - you find the important problem and go solve it.\nWhat helps you stand out:\nBackground in fintech, trading, or cryptocurrencies.\nExperience handling financial data - pricing, positions, PnL, or market data.\nExperience with pricing, spread, or hedging systems specifically.\nExperience with market microstructure or multi-venue execution and smart order routing.\nWhat Success Looks Like\nThe trading and hedging systems you own are correct, observable, and resilient - failures are contained, detected early, and recoverable.\nArchitectural decisions hold up without fundamental rework within 12 to 18 months.\nEngineers across both pods ship faster because of the abstractions, tooling, and standards you've built.\nSystemic risks are anticipated and addressed before they become incidents or PnL surprises.\nYou've raised the technical ceiling of trading and hedging engineering at OpenFX, not just delivered individual projects.\nWhat We Offer\nCompetitive salary and benefits package.\nEquity in a rapidly growing company.\nOpportunity to work in a fast-paced startup at the forefront of fintech innovation.\nOpportunity to make a significant impact on global financial infrastructure.\nCollaborative work culture with emphasis on personal and professional growth.\nWe are committed to building a diverse and inclusive workplace. All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, disability, or veteran status.","description_format":"text","description_chars":5199,"description_truncated":false,"requirements":{"experience_years_min":7,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Equity"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Payment Processing & Gateways","Currency Exchange & FX Payments"],"lifecycle":[{"event":"open","at":"2026-09-11T13:59:29Z"}],"visa":[],"liveness":{"score":62,"band":"ok","label":"Likely open","p_open":1,"p_active":0.86,"p_room":0.72,"age_days":91,"expected_fill_days":186,"reasons":["conf:2","win:mid","crowd:"],"computed_at":"2026-11-06T05:58:05Z"},"pay":null,"html_url":"https://alion.io/job/openfx-senior-backend-engineer-l5-core-trading","json_url":"https://alion.io/job/openfx-senior-backend-engineer-l5-core-trading.json","meta":{"generated_at":"2026-11-06T09:30:07Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":17181,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-07T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":6134},"rest":"https://alion.io/mcp/rest/get_company?id=6134"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fopenfx-senior-backend-engineer-l5-core-trading"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fopenfx-senior-backend-engineer-l5-core-trading"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fopenfx-senior-backend-engineer-l5-core-trading"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/openfx-senior-backend-engineer-l5-core-trading\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fopenfx-senior-backend-engineer-l5-core-trading"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":745444}},{"tool":"search_jobs","arguments":{"company":"openfx.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":745444},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
