We blend cutting-edge technology with the craft of five-star chauffeuring to deliver an experience trusted by more than 100,000 active riders and 1,200 corporate accounts.\nWe’re a profitable, fast-growing scale-up with $43M raised and over $100M in annual revenue. Having recently launched in New York City, we’re expanding rapidly across the US and EMEA. If you take pride in your craft and want to help shape the next chapter of our growth, we'd love to hear from you.\nAbout the Role\nOur Mapping team tackles the spatial intelligence of the platform: road matching, low-latency ETA predictions, and processing thousands of coordinates every second to ensure every journey is accurately tracked.\nWe’re looking for a Mid/Senior Backend Engineer to join a team that keeps frameworks lean and focuses on what matters: clean, maintainable code, shipped fast with TDD, DDD, and continuous integration and delivery.\nWe are a Go shop, and while we’re busy migrating away from our Ruby monolith, our stack includes PostgreSQL, MongoDB, RabbitMQ, Redis, gRPC, and Thrift. Everything runs on AWS and Kubernetes, managed via Terraform.\nOur interview process includes a recruiter screen, algorithms and live coding. Senior+ candidates also complete a system design section and a structured review of past experience and achievements.\nResponsibilities\nWrite high-quality, performant code primarily in Go.\nImplement new microservices while helping us responsibly manage and migrate away from legacy services.\nWork closely with product managers, designers, and data scientists to turn abstract requirements into concrete technical designs.\nEnsure our systems stay responsive under heavy load, optimising for both latency and reliability.\nRequirements\n3+ years of experience (5+ years for seniors) building and maintaining scalable backend services.\nWe use Go. If you know it, great. If not, we’ll interview you in your strongest language (Python, C++, Ruby, etc.). We hire for engineering fundamentals, not syntax.\nIn-depth knowledge of relational and NoSQL databases (PostgreSQL, MongoDB, Redis) and experience with message brokers like RabbitMQ or Kafka.\nAt least 1 year of hands-on experience with mapping-related work such as processing noisy geospatial data, map-matching techniques, or road network graphs and routing algorithms.\nUpper-Intermediate (B2) English proficiency or higher. You should be comfortable debating technical trade-offs with your peers.\nNice To Have\nDriver-side intuition for navigation systems (rerouting behavior, GPS drift, missed turns, real-world edge cases).\nExperience with routing engines like OSRM.\nProficiency in C++.\nFamiliarity with open geospatial datasets such as OpenStreetMap.\nWhat We Offer\nOffice-based role in West London, four days a week with flexible start and finish times, plus one remote day of your choice\nSalary: £90,000 - £120,000\nEmployee stock options plan\nPrivate medical and dental insurance\nLife and critical illness cover\nLatest-generation MacBook Pro and 4k display\nMonthly credit towards Wheely journeys\nCycle to Work scheme\nProfessional development stipend\nRelocation support, including visa sponsorship and allowance\nAll of your personal information will be collected stored and processed in accordance with Wheely’s Candidate Privacy Notice","description_format":"text","description_chars":3408,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[{"language":"English","level":"Upper-Intermediate (B2)","optional":false}]},"benefits":["Apple Macbook","Dental insurance","Professional development","Stock options"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":true,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-08T14:43:01Z"}],"visa":[],"liveness":{"score":63,"band":"ok","label":"Likely open","p_open":1,"p_active":0.632,"p_room":1,"age_days":3,"expected_fill_days":29,"reasons":["conf:1","stale_co","velocity","win:early"],"computed_at":"2026-10-12T06:55:09Z"},"pay":{"stated_usd_annual":158591,"is_top_pay":false},"html_url":"https://alion.io/job/wheely-backend-engineer-midsenior-maps","json_url":"https://alion.io/job/wheely-backend-engineer-midsenior-maps.json","meta":{"generated_at":"2026-10-12T17:55:12Z","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":28765,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-13T00:00:00Z"}},"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":172529},"rest":"https://alion.io/mcp/rest/get_company?id=172529"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fwheely-backend-engineer-midsenior-maps"},{"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%2Fwheely-backend-engineer-midsenior-maps"},{"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%2Fwheely-backend-engineer-midsenior-maps"},{"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/wheely-backend-engineer-midsenior-maps\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fwheely-backend-engineer-midsenior-maps"}]}
