I’m hiring a Senior Backend Enginee r to join the Data Core team at Modash.\nModash helps brands find, understand, and work with creators across Instagram, TikTok, and YouTube. More than 2,700 companies (including Stanley 1913, Sennheiser, and NordVPN) use us to manage and scale their creator partnerships.\nEvery one of those products depends on fresh, reliable creator data. Data Core owns the systems that collect and maintain profiles for 400M+ creators across social platforms, process billions of data points, and keep the rest of Modash supplied with the raw material it needs.\nThat’s where you come in.\nWhy we're hiring\nData Core isn't an internal support team. It owns the collection infrastructure that the entire Modash product (and every downstream data team) depends on.\nCollecting social data at this scale is a hard distributed-systems problem. APIs change without warning. Providers become unreliable. Platforms rate-limit requests. Data grows stale. A tiny inefficiency becomes expensive when repeated hundreds of millions of times.\nWe need a senior engineer who can design resilient services, make thoughtful tradeoffs between coverage, freshness, reliability, and cost, and take production-critical systems from a rough idea to dependable operation.\nYou’ll join the specialised Data Core team and work closely with Data Search, Data Insights, product teams, and company leadership. You’ll have real ownership, but you won’t work in isolation.\nIf you want a feel for how we think about building software, check our Engineering Blog.\nWhat you'll actually own\n1. Keep creator data flowing at massive scale.\nYou’ll build and evolve the systems that collect and maintain 400M+ creator profiles across Instagram, TikTok, and YouTube, keeping billions of data points fresh enough for search, analytics, APIs, and customer-facing products.\n2. Make collection resilient when the outside world isn't.\nYou’ll design services that handle third-party API instability, rate limits, provider outages, platform changes, and partial failures without turning every disruption into a customer incident.\n3. Improve the economics of collection.\nAt this scale, every request, proxy call, retry, storage decision, and compute cycle matters. You’ll improve coverage and freshness while keeping the system financially sustainable.\n4. Own production, not just the code.\nYou’ll shape the problem, design the architecture, write and review the code, ship it, observe it, and improve it. You’ll build the monitoring and operational safeguards that catch gaps and regressions before customers do.\nWhat the day-to-day looks like\nHere’s what a typical week might include:\nMonday. A social platform has changed its behaviour overnight. Collection success has dropped, but only for part of the traffic. You trace the failure pattern, protect downstream freshness, and design a resilient fix rather than a brittle patch.\nTuesday. Deep-focus time. You redesign part of the subscription system that decides which creators to collect, when, and how often, balancing customer value against request and compute cost.\nWednesday. You pair with a Data Search engineer on an indexing dependency. Together, you agree on a cleaner contract that improves freshness without coupling the two teams’ systems.\nThursday. You review a new request-routing approach across proxy providers. You model throughput, failure modes, and unit economics before shipping a small production experiment.\nFriday. An observability review reveals a slow coverage regression that existing alerts missed. You improve the data-quality checks so the team catches the next one before it reaches customers.\nWe keep meetings purposeful and protect time for deep work. You’ll have a short standup, close collaboration when it helps, and plenty of space to design, build, harden, and operate systems.\nRequirements\nWhat you've done before\nBuilt large-scale backend or data systems. You have solid experience with high-volume services where reliability, throughput, latency, and cost all matter.\nShipped systems from concept to production. You’ve owned scoping, architecture, implementation, release, operation, and iteration, not just one layer of the solution.\nDesigned distributed systems. You can reason clearly about partial failure, retries, idempotency, backpressure, scaling, and operational tradeoffs.\nBuilt resilient integrations. You’ve worked with third-party APIs or other external dependencies that are rate-limited, unstable, or liable to change.\nWorked with proxy management or request routing. You understand the practical challenges of routing high-volume traffic and navigating anti-bot systems responsibly at scale.\nTaken operational ownership. You care about observability, alerting, runbooks, and what happens after deployment, not just whether the code merged.\nWorked autonomously on ambiguous problems. You know how to gather requirements, ask useful questions, and make progress without waiting for a perfectly specified ticket.\nCommunicated clearly across teams. You can explain tradeoffs, give direct feedback, and collaborate without creating unnecessary process.\nBonus points if you’ve worked with social-media APIs, data-quality frameworks, large-scale collection systems, or freshness and coverage monitoring. Curiosity about the creator economy helps too, but we’ll get you up to speed.\nOur stack\nAWS, with Pulumi for infrastructure as code\nTypeScript and Node.js as the primary languages\nAurora Limitless/Postgres for subscription and collection state\nS3 for raw data-lake storage\nCloudWatch for observability and alerting\nProxy networks and custom routing layers\nECS, SQS, Athena, and other AWS services\nSlack, GitHub, Linear, Notion, and Cursor\nThe interview process\nWe move quickly and can complete the process in under a week:\nIntro chat\nCoding interview\nSystem design interview\nTeam interview\nCulture and alignment conversation with our CEO, Avery Schrader\nBenefits\nWhat we offer\nFully remote in Europe Work from wherever you do your best work, with some overlap with GMT+3.\nCompensation. Your compensation is made up of salary and stock options. As we're growing fast, the stock option package is especially significant. Annual salary range is 80,000€ - 110,000€ for this role. We hire across Europe, so the exact number depends on your location, employment type, skills, and experience.\nFlexible hours We care about outcomes, not when you log on.\nUnlimited paid vacation If you’re rested and happy, you do better work. Take what you need.\nPersonal development support Courses, books, and conferences are on us when they help you grow.\nReal ownership Take production-critical infrastructure from idea to operation without layers of unnecessary process.\n Regular offsites We’re remote-first, but we make time to connect, collaborate, and have fun together in person.\nAnd a little more about us...\nFounded in 2018 by a high-school dropout and a Canadian (yes, we’re also shocked it’s going so well), Modash is building a suite of tools that help brands scale partnerships with online content creators.\n2,700+ companies like Stanley 1913, Sennheiser, and NordVPN already use Modash to manage and scale their influencer marketing work. And we're just getting started. Over the coming decade, brand investment in creators will continue to boom, and Modash will be at the centre of it all.\nModash is here to stay. We have 8-figures in ARR across two products, a $12M series A investment, and we are default alive. We are building a company that will still be here in 20 years; not rushing towards an exit.\nWe’re almost 100 people distributed across 20+ countries, operating with a fast, async-first culture. If you join Modash, you’ll be surrounded by people who truly want to be the greatest at their craft. People who make you better. Interesting people too, who have done everything from building solar cars, to hanging out with Metallica and Bon Jovi.\nCome join us. Be great, do great things, create great memories, all while making a great impact. Do it.","description_format":"text","description_chars":8047,"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":["Stock options"],"hiring_locations":[{"name":"Germany","iso":"DE","kind":"country"},{"name":"France","iso":"FR","kind":"region"},{"name":"United Kingdom","iso":"GB","kind":"region"},{"name":"Austria","iso":"AT","kind":"region"},{"name":"Belgium","iso":"BE","kind":"region"},{"name":"Bulgaria","iso":"BG","kind":"region"},{"name":"Croatia","iso":"HR","kind":"region"},{"name":"Czech Republic","iso":"CZ","kind":"country"},{"name":"Denmark","iso":"DK","kind":"region"},{"name":"Finland","iso":"FI","kind":"region"},{"name":"Hungary","iso":"HU","kind":"region"},{"name":"Ireland","iso":"IE","kind":"region"},{"name":"Italy","iso":"IT","kind":"region"},{"name":"Netherlands","iso":"NL","kind":"region"},{"name":"Norway","iso":"NO","kind":"region"},{"name":"Poland","iso":"PL","kind":"country"},{"name":"Romania","iso":"RO","kind":"country"},{"name":"Spain","iso":"ES","kind":"region"},{"name":"Sweden","iso":"SE","kind":"region"},{"name":"Switzerland","iso":"CH","kind":"region"},{"name":"Estonia","iso":"EE","kind":"country"},{"name":"Greece","iso":"GR","kind":"region"},{"name":"Iceland","iso":"IS","kind":"region"},{"name":"Latvia","iso":"LV","kind":"region"},{"name":"Liechtenstein","iso":"LI","kind":"region"},{"name":"Lithuania","iso":"LT","kind":"country"},{"name":"Luxembourg","iso":"LU","kind":"region"},{"name":"Malta","iso":"MT","kind":"region"},{"name":"Portugal","iso":"PT","kind":"region"},{"name":"Slovakia","iso":"SK","kind":"region"},{"name":"Slovenia","iso":"SI","kind":"region"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Influencer Marketing"],"lifecycle":[{"event":"open","at":"2026-10-02T18:58:11Z"}],"visa":[],"liveness":{"score":23,"band":"cold","label":"Long shot","p_open":1,"p_active":0.412,"p_room":0.55,"age_days":9,"expected_fill_days":7,"reasons":["conf:1","win:tail","comp:attention"],"computed_at":"2026-10-12T06:55:09Z"},"pay":{"stated_usd_annual":123275,"is_top_pay":false},"html_url":"https://alion.io/job/modash-senior-backend-engineer-data-core-remote-europe","json_url":"https://alion.io/job/modash-senior-backend-engineer-data-core-remote-europe.json","meta":{"generated_at":"2026-10-13T05:26:44Z","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":8438,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-14T00:00:00Z"}},"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":56216},"rest":"https://alion.io/mcp/rest/get_company?id=56216"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fmodash-senior-backend-engineer-data-core-remote-europe"},{"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%2Fmodash-senior-backend-engineer-data-core-remote-europe"},{"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%2Fmodash-senior-backend-engineer-data-core-remote-europe"},{"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/modash-senior-backend-engineer-data-core-remote-europe\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fmodash-senior-backend-engineer-data-core-remote-europe"}]}
