Since 2014, we’ve helped over 50,000 clients bring live music to life’s biggest moments, from weddings to corporate events, and more. We’re passionate about supporting musicians and have helped them earn over £27 million through Encore gigs. By joining Encore, you’ll be joining a bright, friendly and ambitious team on a mission to bring more great live music into the world.\nEncore was acquired by Mixcloud in Autumn 2024, which has marked the beginning of an exciting new chapter in our story. Together, we’re solving meaningful challenges in our industry such as, how can we make live music accessible to everyone while enabling musicians to build sustainable careers? And how do we make the booking process an intuitive and enjoyable digital experience? We're excited to execute these ideas and are looking for an experienced engineer to join us on the journey.\nThe Role\nWe're looking for a Lead Engineer to join our small, full-stack engineering team. You'll be working alongside our other Senior Engineer as one of just two developers responsible for the entire Encore platform - from the customer-facing web app to our React Native mobile app, backend services, and infrastructure.\nYou'll join at a pivotal moment: we're mid-way through launching Encore in the USA, evolving our core product, and rolling out a rebrand across the site. There's a lot of green-field, high-impact work on the table, alongside the day-to-day of keeping a live, revenue-generating marketplace running smoothly.\nWhat You’ll Do\nTransform Encore into a more focused, intuitive self-serve platform for both musicians and customers, making it seamless and delightful to use.\nBring systems-level understanding and stewardship of strategy to the tech/product team (and across the company)\nPastoral mentorship of another full-stack engineer\nMaintenance of our tech infrastructure (keeping downtime to a minimum, and fixing critical bugs/team requests in a prioritised and timely manner)\nContinuous formation/refinement of tech projects of strategic importance (e.g, tech debt, stack modernisation)\nDeliver on the release cadence for tech/product projects of strategic importance\nImprove Encore key features including messenger, job listings, search and musician admin panels\nContinued build-out of the USA platform - SEO landing pages, musician-side functionality, and bringing the US experience up to parity with the UK platform\nKeep technical output closely and visibly aligned with commercial priorities, and always identify the highest-impact work and the next bottleneck to remove\nKeep the platform reliable - minimising downtime and resolving critical bugs and team requests in a timely, well-prioritised way\nWork with bespoke payment integrations, including Stripe for the US market\nReduce tech debt on an ongoing basis - including migrating toward a more formalised meta framework and moving our WordPress blog off Digital Ocean and onto Railway\nRequirements\nWho you are:\nLead-level engineering ownership in a production software environment\nStrong full-stack experience with TypeScript/JavaScript - comfortable across the stack rather than specialised in just one layer\nExperience with React for frontend and Node.js/Express for backend services\nComfort moving between frontend web work and infrastructure/DevOps tasks (containers, cloud configuration) - at Encore, engineers regularly jump between the two\nExperience working with AI-assisted coding tools, such as Claude Code Skills, MCP servers and Routines.\nA product and commercial mindset: the ability to weigh technical work against business impact, prioritise ruthlessly, and know what to cut to ship faster\nStrong communication skills - you'll work closely with product, design, non-technical stakeholders, and leadership on technical priorities across the company\nComfort operating with autonomy as an individual contributor; we don't micro-manage, and you'll be trusted to make day-to-day technical decisions independently\nExperience with (or willingness to quickly get up to speed on) our stack: React Native/Expo, Railway, GitHub (incl. CI and end-to-end testing), Playwright, Vite/Vitest, Google Cloud, AWS, Twilio, and Stripe\nEligible to work in the United Kingdom\nNice to Have:\nTanStack Start/Router experience\nA passion for music - not essential, but the whole team shares a genuine love of it, and many of us are musicians or DJs ourselves\nExperience working in a two-sided marketplace business\nExperience navigating a codebase that has evolved and grown over several years, with an eye for where to simplify, unify, or replace legacy pieces\nDegree in Computer Science or Software Engineering\nBenefits\nWhat Makes This Role Special\nZero-to-one impact: Be at the forefront of solving some of the music industry’s most intriguing challenges.\nReal problem-solving: You’ll work on complex, meaningful challenges that impact thousands of musicians and event organisers.\nTrue ownership: Take the lead in shaping product direction and enjoy a high level of autonomy in your work.\nDirect impact: Work in a small, dynamic team where your contributions directly affect our users’ experiences.","description_format":"text","description_chars":5317,"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":[],"hiring_locations":[{"name":"United Kingdom","iso":"GB","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Media & Entertainment","Streaming & OTT Platforms"],"lifecycle":[{"event":"open","at":"2026-09-06T07:33:00Z"}],"visa":[{"country":"GB","licensed_sponsor":true,"evidence":"Licensed UK visa sponsor (Skilled Worker)","filings_12m":null,"filings_prev_12m":null,"green_card_filings_12m":null,"median_offered_wage_usd":null,"route":"Skilled Worker","cap_exempt":false,"checked_at":"2026-10-31T06:23:40+00:00","sources":["UK Home Office: register of licensed sponsors (workers)"],"filings_for_role_12m":0}],"liveness":{"score":11,"band":"cold","label":"Long shot","p_open":1,"p_active":0.394,"p_room":0.28,"age_days":110,"expected_fill_days":28,"reasons":["conf:6","win:tail","crowd:"],"computed_at":"2026-10-31T05:58:55Z"},"pay":null,"html_url":"https://alion.io/job/mixcloud-lead-javascript-engineer-encore-musicians","json_url":"https://alion.io/job/mixcloud-lead-javascript-engineer-encore-musicians.json","meta":{"generated_at":"2026-10-31T23:17:35Z","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":36398,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-01T00:00:00Z"}},"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":172333},"rest":"https://alion.io/mcp/rest/get_company?id=172333"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fmixcloud-lead-javascript-engineer-encore-musicians"},{"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%2Fmixcloud-lead-javascript-engineer-encore-musicians"},{"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%2Fmixcloud-lead-javascript-engineer-encore-musicians"},{"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/mixcloud-lead-javascript-engineer-encore-musicians\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fmixcloud-lead-javascript-engineer-encore-musicians"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":443116}},{"tool":"search_jobs","arguments":{"company":"mixcloud.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":443116},"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.
