Today’s electricity system was not designed for rapid decarbonisation, AI-driven efficiency or fair access for the actual users - businesses and generators.\nWe’ve built the first AI native transaction infrastructure to reinvent how electricity is bought, sold and priced. Our technology is designed to cut out the inefficient fees, automate complex market flows, and bring transparency and fairness to energy transactions at scale.\nIn late 2025, after extraordinary growth, we closed a $75 million Series B - led by Lightspeed Venture Partners with participation from Albion, Atomico, Allianz, Hitachi Ventures, Hitachi Ventures, Schroders Capital and others - positioning us for global expansion, deeper product innovation and category leadership.\nWe’re scaling internationally and building toward a future where AI-driven infrastructure is foundational to electricity markets worldwide.\nSince launch, our modern utility product, known as RED, has already facilitated thousands of business customers and billions in energy transaction value, proving that modern software and AI can transform an industry built on legacy systems.\nAt tem, we’re not just building another energy company, we’re rearchitecting market infrastructure so that transparency, efficiency and sustainability become the default, not the exception.\nThe Role\nWe're hiring a Senior Data Engineer.\nData sits at the core of what tem does. Our time-series data is the spine that runs from pricing through to billing: every transaction depends on it working. You'll be working across a genuinely varied set of workloads: textual data, time-series data, and event streams, each with its own ingestion and reliability challenges, including TSDS.\nYou'll join our Data Service team of 4, owning the design, reliability, and recovery strategy of specific ingestion pipelines and systems end-to-end. This is an individual contributor role: no team to manage, full ownership of the work you do. The team has more work than hands right now, and this role exists to close that gap so the business can move faster on the data it depends on.\nYou'll also work closely with our AI initiatives as they grow: the platform you own increasingly becomes the foundation those efforts depend on.\nYou will:\nOwn the design, reliability, and recovery strategy for the ingestion pipelines and systems in your domain.\n\nMaintain and improve the data platform, including working through the existing tech debt backlog.\n\nBuild monitoring and alerting so issues surface before they become incidents.\n\nSet the data quality checks that make an SLA commitment possible, and hold the line on them.\n\nHelp take the number of data products with a defined SLA from 2 to 10.\n\nResponsibilities\nData Ingestion\nOwn the design, reliability, and resilience of ingestion pipelines end-to-end, including TSDS, with a clear recovery strategy when things break.\n\nBuild and maintain ETL/ELT pipelines for new and existing data sources.\n\nDecide the right approach (batch vs. streaming) for each pipeline in your domain, including high-scale, low-latency requirements for time-series data.\n\nSet data quality checks that make an SLA commitment possible, and hold the line on them.\n\nPlatform Maintenance\nOwn the day-to-day reliability of the data platform: monitoring, testing, and fixing issues before they become firefights.\n\nOwn code quality and standards for the systems you're responsible for, including CI checks (linting, tests, coverage).\n\nWork through the existing tech debt backlog, prioritising fixes that unblock SLA commitments.\n\nOptimise pipelines for performance and cost as data volumes grow.\n\nHandle the failure modes specific to energy data: late arrivals, reprocessing, backfills.\n\nMonitoring & Alerting\nBuild and improve observability across your systems so problems surface before they cause downstream impact.\n\nSet up alerting tied to the SLAs the team is committing to.\n\nInvestigate and resolve issues within your domain, escalating genuinely cross-system problems.\n\nSupporting Expansion\nHelp scope and prepare the platform for new data sources tied to international expansion.\n\nFlag where current architecture won't hold up as scope grows, even if fixing it isn't your call to make alone.\n\nWork closely with the AI team as their data needs on the platform grow.\n\nRequirements\nMust haves\nStrong Python skills, with proven experience building and maintaining production data pipelines.\n\nExperience owning the design, reliability, and resilience of a data pipeline or system end-to-end, not just writing pipeline code.\n\nAWS or GCP experience.\n\nGreat communication skills, comfortable working directly with stakeholders to scope and agree SLAs, and explaining technical trade-offs to non-technical audiences.\n\nStrong team player, comfortable working independently against a backlog and making judgement calls on prioritisation, while fitting into an existing team of 4.\n\nTerraform experience.\n\nBonus points\nExperience with time-series data at scale.\n\nExperience with modern data stack tooling (Airflow, Snowflake, BigQuery, Redshift, ClickHouse).\n\nExperience in energy or climate tech.\n\nBackground in high-growth startups or scale-ups.\n\nGenuine interest in how AI tooling and workflows intersect with data engineering.\n\nWe're open to someone who doesn't tick every box here, as long as they bring solid AWS or GCP experience and the ability to own their own work end-to-end.\nBenefits & Perks\nSalary aligned to internal benchmarks and reviewed twice a year.\n\nStock options so everyone has ownership in our mission.\n\n25 days holiday plus public holidays. Swap public holidays for the ones that matter most to you, and enjoy your birthday off.\n\nRemote first and flexible working, with clear core hours and no internal meetings on Friday afternoons.\n\nHome working and wellbeing budgets:\nUp to GBP1,200 or EUR1,200 per year for your remote setup.\n\nUp to GBP150 or EUR150 per month for wellbeing.\n\nInterview Process\nWe move fast. Most processes take 2 to 3 weeks from first chat to offer. If you need us to adapt anything, let us know.\nIntro call with Talent, 30 minutes.\n\nBehavioural interview, 60 minutes.\n\nSkills interview with cross-functional leaders, 60 to 90 minutes, including a practical exercise.\n\nBar Raiser interview with leadership stakeholders, 45 minutes.\n\nWe welcome applications from people of all backgrounds, experiences, and identities, including those that are traditionally underrepresented in the tech and energy sectors. If you’re excited about this role but not sure you meet every requirement, we’d still love to hear from you. Your unique perspective could be exactly what we’re looking for.","description_format":"text","description_chars":7025,"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":["Flexible schedule","Stock options"],"hiring_locations":[{"name":"United Kingdom","iso":"GB","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Smart Grid","Energy Management"],"lifecycle":[{"event":"open","at":"2026-09-10T18:18:46Z"}],"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":"2026-10-17T06:21:15+00:00","sources":["UK Home Office: register of licensed sponsors (workers)"],"filings_for_role_12m":0}],"liveness":{"score":32,"band":"fade","label":"Fading","p_open":1,"p_active":0.354,"p_room":0.9,"age_days":36,"expected_fill_days":58,"reasons":["conf:2","velocity","win:mid"],"computed_at":"2026-10-17T05:46:00Z"},"pay":{"stated_usd_annual":123548,"is_top_pay":false},"html_url":"https://alion.io/job/tem-energy-senior-data-engineer","json_url":"https://alion.io/job/tem-energy-senior-data-engineer.json","meta":{"generated_at":"2026-10-17T06:49:38Z","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":9403,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-18T00:00:00Z"}},"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":580},"rest":"https://alion.io/mcp/rest/get_company?id=580"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ftem-energy-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%2Ftem-energy-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%2Ftem-energy-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/tem-energy-senior-data-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ftem-energy-senior-data-engineer"}]}
