We make complex steps easier to navigate so business owners can focus on building what comes next.\nAbout the role:\nBizee helps entrepreneurs start and grow their businesses. We're looking for a hands-on software engineer to build the data platform used across the organisation. You'll build and own systems that make data available to products, operations, marketing, finance and AI applications, so teams can build services, automate work, experiment and make better decisions.\nYou'll build the paths from source data to action and back to observed outcomes. That includes pipelines, shared data models and APIs that give people and AI agents the context they need, plus feedback loops that record what happened and support evaluation and improvement. You'll own the work from understanding the need through implementation, deployment and adoption.\nAI coding tools and agents will be a core part of how you build. You'll use them to investigate systems, develop and test changes, and accelerate delivery while applying your own engineering judgment and verifying the result.\nAt L4, you'll independently deliver a defined platform problem when the intended outcome is understood but requirements and implementation are incomplete. You'll investigate existing systems, choose an approach and own implementation, debugging, rollout and adoption. When the work reveals a broader problem, you'll bring evidence and a recommendation on what should change.\nWhat you'll do:\nWork directly with teams across the organisation to understand what they need to build or automate. Turn recurring needs into shared data services and interfaces that teams can use without bespoke integrations or repeated manual work.\n\nBuild pipelines and services that collect, transform and deliver data to operational applications, analytical systems and AI workflows. Handle retries, duplicate events, late-arriving data and replay so systems can recover reliably.\n\nCapture business events and state changes for customers, orders, payments, subscriptions and fulfillment. Establish identifiers, schemas and history that let systems connect activity across the customer journey.\n\nBuild closed feedback loops that connect inputs, decisions and actions to their outcomes. Make that evidence usable for experiments, model and agent evaluation, and improvements to automated workflows.\n\nBuild quality checks, lineage and monitoring into the platform. Detect missing, stale or inconsistent data, trace failures to their source and prevent bad inputs from silently affecting customer experiences or automated decisions.\n\nConnect legacy and new systems while improving the underlying data models and contracts. Validate migrations and changes without disrupting the services and workflows that depend on them.\n\nBuild datasets, APIs and retrieval interfaces that give teams and AI agents access to current and historical context. Make permissions, provenance and freshness clear, and capture outcomes so downstream systems can learn what worked.\n\nUse AI tools throughout implementation, debugging and testing. Own deployment, performance, cost and operational documentation, and leave systems that colleagues can understand and maintain.\n\nWhat you'll bring:\nStrong software engineering fundamentals and experience building and operating production systems, including testing, APIs, failure handling and maintainable design.\n\nStrong SQL and practical experience with data modeling, pipelines and data-serving systems. You can design data for operational and analytical use, trace it to its source and reason about quality, history and consistency.\n\nStrong Python skills and experience using it to build and operate production data pipelines, integrations and services, with testing and maintainable code. Go is our primary backend language; familiarity with it is useful when working with the services that produce and consume data.\n\nExperience with event-driven or distributed systems, including schema evolution, idempotency, replay and consistency. You can choose between batch and streaming approaches based on the need.\n\nA track record of independently taking a defined problem from an incomplete brief to reliable production use. You can explain how you filled gaps in the requirements, made design decisions, resolved dependencies and verified the result.\n\nPractical use of AI coding tools and agents, backed by technical judgment, code review and testing. You understand and remain accountable for generated work.\n\nThe ability to learn business domains, question assumptions and explain trade-offs to technical and nontechnical colleagues. Clear communication in English and ownership through delivery and adoption.\n\nNice to have:\nExperience building shared data platforms, operational data APIs, cloud data infrastructure or migrations between legacy and new systems.\n\nExperience with change data capture, orchestration, transformation frameworks, data lineage or automated data-quality checks.\n\nExperience with feedback loops for AI systems, retrieval, experiment infrastructure or connecting model and agent decisions to observed outcomes.\n\nWhat we offer\nCompetitive compensation 27,000-38,000 PLN/month, stock options, and an annual bonus.\n\nA flexible benefits allowance to spend on what matters to you.\n\nAn office in the city center and a friendly, non-corporate atmosphere.\n\nReal ownership and the opportunity to make a visible impact.\n\nTech stack\nPython\nSQL\nData modeling\nDistributed systems\nAI","description_format":"text","description_chars":5621,"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":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Legal Services","Accounting & Bookkeeping Services"],"lifecycle":[{"event":"open","at":"2026-10-30T14:25:00Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":3,"expected_fill_days":80,"reasons":["seen:3","velocity","win:early"],"computed_at":"2026-11-03T05:54:40Z"},"pay":{"stated_usd_annual":116064,"is_top_pay":false},"html_url":"https://alion.io/job/bizee-senior-software-engineer-data-platform","json_url":"https://alion.io/job/bizee-senior-software-engineer-data-platform.json","meta":{"generated_at":"2026-11-03T08:34:23Z","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":12062,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-04T00:00:00Z"}},"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":3775},"rest":"https://alion.io/mcp/rest/get_company?id=3775"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fbizee-senior-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%2Fbizee-senior-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%2Fbizee-senior-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/bizee-senior-software-engineer-data-platform\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fbizee-senior-software-engineer-data-platform"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3526778}},{"tool":"search_jobs","arguments":{"company":"bizee.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3526778},"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.
