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 Senior Backend Engineer for our Trading team - the team that owns the client's entire trade experience.\nTrading 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.\nYou 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.\nWe'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).\nKey Responsibilities\nDesign, build, and operate services across the trade path - quoting, pricing, spread application, and trade lifecycle management.\nOwn features end-to-end: scoping, technical design, delivery, rollout, and the operational health of what you ship.\nDrive work to closure with Product, Design, and Operations. You are accountable for adoption, not just delivery.\nAct as a product engineer - scope a problem statement, understand its product impact, and take the hard prioritisation calls.\nBuild for correctness and latency on a live client trade path. Understand and weigh trade offs.\nInstrument what you build - logging, metrics, and alerting that make the behaviour of the trade path predictable in production.\nDesign for failure: retries, idempotency, and safe recovery when a downstream dependency misbehaves.\nExpose trading capability across surfaces - GUI, public API, and conversational AI - with clean, stable contracts.\nRaise the bar through code review and design feedback, and mentor L1/L2 engineers on the team.\nBuild a healthy engineering-excellence and tech-debt backlog - surface the right items, work with the EM on a resolution plan, and drive them to closure.\nParticipate in on-call, respond to incidents with urgency, and turn post-mortems into durable fixes.\nWork directly with product and the Hedging team to connect what you build to Total Payment Volume and gross revenue.\nWhat we are looking for\nMust-haves:\n4-6 years of experience building and operating production backend systems.\n A trading background - you've worked at a trading company, exchange, or brokerage and have built systems on a live trade or order path (e.g. CoinDCX, Groww, CoinSwitch Kuber, or similar).\nStrong fundamentals in system design, data modelling, and API design, with practical experience in distributed systems.\nSolid command of object-oriented programming principles and low-level design patterns.\nSolid production engineering instincts - observability, debugging complex systems, performance tuning, and incident response.\nComfort with abstract, ambiguous problems - you can turn a vague mandate into scoped, sequenced deliverables without waiting for someone to specify it for you.\nHands-on and high agency. You find the important problem and go solve it rather than waiting to be assigned it.\nHeavy AI user. You use AI coding tools with real technique and get materially more done because of it.\nData-driven, and a clear written communicator - we are async-heavy and globally distributed.\nWhat helps you stand out:\nExperience with pricing, quoting, or spread engines specifically.\nExperience with FX, multi-currency systems, or cross-border payments.\nExperience with market data, order books, or market microstructure.\nWhat Success Looks Like\nThe services you own on the trade path are reliable, well-tested, and observable - issues are caught before clients notice them.\nYou ship complex features end-to-end from technical design to execution, delivery and adoption.\nThe team moves faster because of your code reviews, documentation, and technical judgment.\nL1/L2 engineers around you grow measurably faster.\nYou become a go-to engineer for the trade path.\nYou raise the bar for the Trading team.\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":5330,"description_truncated":false,"requirements":{"experience_years_min":4,"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":61,"band":"ok","label":"Likely open","p_open":1,"p_active":0.843,"p_room":0.72,"age_days":80,"expected_fill_days":186,"reasons":["conf:1","win:mid","crowd:"],"computed_at":"2026-10-26T05:57:25Z"},"pay":null,"html_url":"https://alion.io/job/openfx-senior-backend-engineer-l3-trading","json_url":"https://alion.io/job/openfx-senior-backend-engineer-l3-trading.json","meta":{"generated_at":"2026-10-26T08:02:07Z","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":10614,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-27T00:00:00Z"}},"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-l3-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-l3-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-l3-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-l3-trading\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fopenfx-senior-backend-engineer-l3-trading"}]}
