Electricity demand is expected to double by 2050. Market price volatility and complexity are here to stay - and the backbone of Europe's industrial economy is at risk.\nAt trawa, we're building the solution: an integrated B2B energy platform combining procurement, energy management, and flexibility steering in a single product. That integration unlocks up to 30% in recurring electricity cost savings while helping companies make the switch to renewables.\nWe're a Berlin-based scale-up of around 100 people. We've raised over €35M to date - including a €24M Series A in May 2025 - backed by Balderton, Headline, Speedinvest, AENU, Magnetic, and Tiny VC. All three founders are fully committed to building the utility of the future.\nThe Team\nData Intelligence (DINTEL) is an engineering team that owns trawa's data pipelines, and analytics infrastructure. We manage the full data lifecycle - from ingesting raw metering and market data, to invoicing and self-service analytics.\nAbout the Role\nWe're looking for a Senior Data Engineer to own and lead the development, reliability, and continuous evolution of our data platform. This is a high-ownership, high-autonomy role. You'll work across production systems at scale - defining technical direction, coordinating cross-team dependencies, and driving measurable impact across data engineering, analytics infrastructure, and operational tooling.\nYou'll mentor teammates and be supported by experienced engineering leaders as you continue to grow your own leadership and technical skills.\nAt trawa, our culture is generally \"office-first with flexibility\", where most of us are in our beautiful Berlin office the majority of the week, with room to occasionally work from home when needed. The Tech team follows a more hybrid rhythm, spending around 2-3 days a week in the office. We don’t set fixed office days or track attendance strictly, but teams coordinate what works best for them, because regular in-person collaboration remains an important part of how we work.\nWhat You'll Do\nLead the design, implementation, and operation of critical data pipelines and platform infrastructure on AWS\n\nDefine and evolve data quality standards, observability practices, and operational controls across the platform\n\nLead cross-team technical discussions and help align stakeholders on data platform architecture decisions\n\nDeliver large-scale technical initiatives end-to-end, from design through delivery, collaborating with teams across the business\n\nShape the team's technical culture through code reviews, mentorship, knowledge sharing, and documentation\n\nEvolve our analytics and BI tooling (ClickHouse, Metabase) to support business intelligence and decision-making\n\nBuild and maintain data pipelines using Python (pandas, polars), dbt, and dlt\n\nIdentify and address technical debt, improving platform reliability, scalability, and developer experience\n\nCommunicate the value and impact of platform improvements to engineering and business stakeholders\n\nDiagnose and resolve complex data and performance challenges across multiple systems and services\n\nYour First 90 Days\nFirst 6 Weeks - Getting Oriented\nBuild context across the data platform, including AWS, dbt, dlt, PostgreSQL, ClickHouse, and Python services\n\nBegin contributing to production systems and taking ownership of key platform components\n\nBuild relationships with engineers and stakeholders across the business to understand data needs, priorities, and opportunities for improvement\n\nBy Month 3 - Building Momentum\nTake ownership of significant platform components and drive improvements with growing independence\n\nBegin leading a cross-team initiative with support from your manager and teammates, helping align stakeholders around a clear plan\n\nIdentify and begin implementing a meaningful improvement to platform reliability, observability, or scalability\n\nWhat You'll Gain\nOwnership of a production data platform that directly powers trawa's energy trading, invoicing, and analytics\n\nThe opportunity to work closely with engineering and business stakeholders on high-impact initiatives with company-wide visibility\n\nA chance to shape technical culture and contribute to the evolution of engineering practices across the Data Intelligence team\n\nDeep expertise across a modern data stack, including AWS, Python (pandas, polars, FastAPI), dbt, dlt, PostgreSQL, ClickHouse, and Metabase\n\nSupport in growing your technical and leadership skills, with a clear progression framework and meaningful opportunities for advancement\n\nWhat We're Looking For\nWe know that great candidates don't always match every requirement. If you're excited about the role and believe you can contribute to our mission, we'd love to hear from you, even if your experience doesn't perfectly align with every qualification listed.\nCore Requirements\n5+ years of experience in data engineering or a related field\n\nStrong SQL and Python skills\n\nExperience building and operating production data systems\n\nExperience collaborating across teams to deliver technical projects\n\nNice to have\nHands-on experience with parts of our stack, including dbt, dlt, ClickHouse, PostgreSQL, Metabase, or AWS\n\nExperience with workflow orchestration tools such as Airflow\n\nFamiliarity with energy markets, time-series data, or operational data platforms\n\nExperience in a technical leadership role\n\nWhat Helps You Succeed Here\nExperience designing scalable and reliable data systems\n\nEnjoy mentoring and supporting the growth of teammates\n\nComfort navigating ambiguity and helping bring clarity to complex problems\n\nStrong communication and stakeholder-management skills\n\nWhy Join Us\nReal impact - Join one of Europe's fastest-growing B2B energy platforms at a pivotal moment. Your work will directly support systems that help industrial companies cut costs and go green.\nEarly ownership - We give team members responsibility from day one. You won't be shadowing - you'll be shipping.\nMentorship that matters - Regular leadership sessions, cross-functional exposure, and engineers who are genuinely invested in your growth.\nLearning culture - Annual learning budget, dedicated development time, and a team that takes knowledge-sharing seriously.\nInclusive by design - 15+ nationalities, family-friendly policies, and a genuine commitment to building a place where everyone can do their best work.\nSolid benefits - A competitive package covering wellbeing, learning, and team experiences.","description_format":"text","description_chars":6561,"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":[]},"benefits":[],"hiring_locations":[{"name":"Germany","iso":"DE","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Blockchain & Crypto","Energy & Utilities","Energy Management"],"lifecycle":[{"event":"open","at":"2026-09-11T07:56:32Z"}],"visa":[],"liveness":{"score":15,"band":"cold","label":"Long shot","p_open":1,"p_active":0.523,"p_room":0.28,"age_days":135,"expected_fill_days":46,"reasons":["conf:3","win:tail","crowd:"],"computed_at":"2026-10-29T05:49:05Z"},"pay":null,"html_url":"https://alion.io/job/trawa-senior-data-engineer","json_url":"https://alion.io/job/trawa-senior-data-engineer.json","meta":{"generated_at":"2026-10-29T13:23:58Z","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":20110,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-30T00:00:00Z"}},"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":686410},"rest":"https://alion.io/mcp/rest/get_company?id=686410"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ftrawa-senior-data-engineer"},{"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%2Ftrawa-senior-data-engineer"},{"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%2Ftrawa-senior-data-engineer"},{"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/trawa-senior-data-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ftrawa-senior-data-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":724049}},{"tool":"search_jobs","arguments":{"company":"trawa.de","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":724049},"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.
