We keep raw card data off your systems, cut PCI compliance work, improve acceptance, mitigate fraud and chargebacks and decrease your cost of payments, so you keep full control. Trusted by Ramp, Rippling, Modern Treasury and Overwolf; Series B, led by Ribbit Capital.\nRole Overview\nYou’ll be the first engineer dedicated to our data platform, and you’ll design and build it largely from scratch. You’ll own the platform that collects our event data, models it, and serves it to customers with roughly 15-second freshness, including building our time-series foundations. This is a senior, hands-on role: you’ll set the architecture, write most of the code and set the bar for the data team that grows around you. You’ll work closely with our VP of Engineering, Product and our leadership team. Product decides which data products to build; you own how they’re built and what the data can support.\nWhat You’ll Be Doing\nDesigning and building real-time ingestion for three sources: events our platform already emits, new instrumentation in our product, and data our customers send us\n\nRebuilding our event streaming layer, with the authority to choose how\n\nModelling structured and time-series data in ClickHouse and Databricks so aggregations, trends and benchmarks are fast and cheap at scale (our current defaults, though you can make the case for change)\n\nDesigning the external data contracts and APIs customers build on, including versioning, reliability and isolation of each customer’s data\n\nDefining the event contracts our product engineers instrument against\n\nOwning the platform in production: monitoring, data quality, cost and on-call for the systems you build\n\nYour First Year\nIn your first few months you’ll assess what we have, decide the platform architecture, and scope our first data product with Product and Engineering. After that, you’ll rebuild the streaming layer and ship the first external product on the new platform, most likely aggregated analytics or direct data access for customers. Later in the year you’ll help us hire a domain expert who decides which signals and benchmarks are worth building. Machine learning is out of scope for now; it comes once we have enough clean historical data.\nRequirements\nProduction experience building real-time or near-real-time ingestion with event streaming, such as Kafka, Kinesis or Redpanda\n\nDeep experience with ClickHouse or a similar analytical database, including modelling time-series data for fast aggregation at volume\n\nA track record of shipping an external, multi-tenant data product or data API that customers depended on (internal reporting pipelines alone won’t cover this)\n\nExperience migrating a messy live system to a new one without downtime or data loss\n\nSenior-level engineering habits: system design, testing, and running the services you build in production\n\nSound judgement working independently: you’ll be our most senior data voice, and we’ll rely on your technical calls\n\nA product mindset: you won’t work directly with customers, but you’ll often be the person who knows what the data can and can’t support\n\nNice to Have\nExperience in payments or with sensitive, regulated data\n\nDatabricks or Spark experience alongside ClickHouse\n\nExperience as an early or founding member of a data team, including hiring\n\nThis Might Not Be for You If…\nYou’re mainly an analyst, BI or data science specialist: this role builds the platform and the external products on it\n\nYour experience is mostly dashboards, internal reporting pipelines or modelling for analysis\n\nYou want a hands-off architect role: you’ll write most of the code\n\nYou want to work fully remotely: we’re in our Shoreditch office Tuesday to Thursday\n\nCompensation, Benefits & Why Join\nCompetitive salary\n\nStock options with an extended exercise window\n\nPrivate health insurance\n\nUnlimited PTO & flexible working hours\n\nDaily lunch budget\n\nBuild a company’s data platform from the first line of code, with the authority to make the big architectural calls and work directly with C-Level\n\nInterview Process\nRecruiter Screen\n\nHiring Manager Interview\n\nTechnical Interview\n\nSystem Design Interview\n\nFinal with our Founder\n\nReferences and Offer\n\nLocation\nThis role is based in London, in our Shoreditch office Tuesday to Thursday. We do not currently sponsor UK work visas.\nCandidates must be based in the location specified. Any applications from candidates not in the required location may not receive a response.","description_format":"text","description_chars":4573,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Flexible schedule","Health insurance","Stock options","Unlimited PTO"],"hiring_locations":[{"name":"United Kingdom","iso":"GB","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Cybersecurity","Payment Processing & Gateways"],"lifecycle":[{"event":"open","at":"2026-11-05T22:27:51Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":1,"expected_fill_days":39,"reasons":["conf:0","velocity","win:early"],"computed_at":"2026-11-07T05:47:08Z"},"pay":null,"html_url":"https://alion.io/job/evervault-seniorstaff-software-engineer-data-platform","json_url":"https://alion.io/job/evervault-seniorstaff-software-engineer-data-platform.json","meta":{"generated_at":"2026-11-07T12:10:24Z","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":13281,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-08T00:00:00Z"}},"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":39164},"rest":"https://alion.io/mcp/rest/get_company?id=39164"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fevervault-seniorstaff-software-engineer-data-platform"},{"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%2Fevervault-seniorstaff-software-engineer-data-platform"},{"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%2Fevervault-seniorstaff-software-engineer-data-platform"},{"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/evervault-seniorstaff-software-engineer-data-platform\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fevervault-seniorstaff-software-engineer-data-platform"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3840314}},{"tool":"search_jobs","arguments":{"company":"evervault.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3840314},"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.
