To learn more, visit https://www.glasslewis.com/.\nWe are looking for a Senior Software Engineer in Madrid to own the data platform in the Foundational Engineering team.\nYou are a software engineer who likes data. You build the systems that send our data to clients. You know how that data moves from its source to the release.\nOur team builds the platform that all of Tech uses. On the data side, the platform has two parts:\nThe data release. This is the regular process that sends our ESG and investment data to clients. An application runs it. The application tracks the state of each release and shows teams what is ready, what failed, and what to retry.\nThe pipeline platform. This is Airflow on Kubernetes. Every team depends on it.\nWhy we are hiring now\nClarity AI and Glass Lewis are now one company. The data platform is at the center of this integration. More data, more products, and more teams will depend on the release. We need a person who can own it in the first months. You will make it more reliable and easier for teams to use on their own. You will also help bring Glass Lewis data into it.\nResponsibilities\nOwn the release application. It is a Python service (FastAPI, Postgres, Argo Workflows) with a web UI. It manages release state, product dependencies, readiness checks, retries, and hotfixes.\nMake the release stable. Find why releases fail and fix the root cause. Automate incident diagnosis, so that each failure tells you its cause.\nRun the pipeline platform. Keep Airflow on Kubernetes healthy, up to date and secure. This includes Helm, secrets, resource sizes, retries after short failures, and monitoring.\nBuild self-service tools for data teams. They must be able to add a product to the release, see its dependencies and debug their own runs. They must not have to wait for us.\nWork with the teams that depend on the release: data, product and client teams. Learn what they need. Agree on data contracts with upstream teams. Decide with the team what to build next.\nHelp design how Glass Lewis data comes into our platform and the release.\nRequirements\n6+ years of software development experience. You have built data-heavy systems or a data platform.\nStrong Python skills, for example, FastAPI. Good design, automated tests, and clean APIs. Go or TypeScript is a plus.\nHands-on work with Airflow or a similar tool. You understand how data moves through pipelines that depend on each other.\nGood SQL. You know Postgres and a cloud data warehouse. Snowflake is best.\nContainers, Kubernetes and CI/CD. You can run what you build in production.\nTesting is part of the work for you, not a step for later. This includes data quality.\nA product mindset. You care about the people who use the platform and about results.\nOwnership. You lead technical designs, deliver large pieces of work across several systems, and get agreement from others.\nExperience with Lean and XP: trunk-based development, TDD, pair and ensemble programming, small safe steps.\nYou use AI agents (Claude Code, Cursor, MCPs, and similar) to build and run systems.\nFluent English. Spanish is a plus.\nYou live in Spain. We pair in real time, so we work in the same time zone.\nNice to have\ndbt, data quality tools (Soda, Great Expectations), and data contracts.\nArgo Workflows, Helm, Terraform on AWS.\nMonitoring for pipelines: Grafana, Loki, Datadog.\nFinancial or ESG data, or data products for clients.\nDDD and Team Topologies.\nWork in a scale-up or SaaS company, or in a merger.Benefits\nComprehensive Private Health Insurance coverage\nAccess to Wellhub wellness and fitness programs\nProfessional Development Stipend to support continuous learning and career growth\nFlexible Benefits Program, including meal vouchers, transportation support, and nursery assistance","description_format":"text","description_chars":4661,"description_truncated":false,"requirements":{"experience_years_min":6,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[{"language":"English","level":"Advanced (C1)","optional":false}]},"benefits":["Continuous learning","Health insurance","Insurance coverage","Professional development"],"hiring_locations":[{"name":"Spain","iso":"ES","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Financial Services","Professional Services","Sales & Marketing","Financial Data & Market Intelligence"],"lifecycle":[{"event":"open","at":"2026-11-11T14:40:14Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":0,"expected_fill_days":36,"reasons":["conf:3","win:early"],"computed_at":"2026-11-11T18:25:34Z"},"pay":null,"html_url":"https://alion.io/job/glass-lewis-co-senior-software-engineer-data-platform-foundational-engineering","json_url":"https://alion.io/job/glass-lewis-co-senior-software-engineer-data-platform-foundational-engineering.json","meta":{"generated_at":"2026-11-11T18:25:34Z","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":35367,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-12T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"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":1910808},"rest":"https://alion.io/mcp/rest/get_company?id=1910808"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fglass-lewis-co-senior-software-engineer-data-platform-foundational-engineering"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":2,"usd":0.2},"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%2Fglass-lewis-co-senior-software-engineer-data-platform-foundational-engineering"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"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%2Fglass-lewis-co-senior-software-engineer-data-platform-foundational-engineering"},{"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/glass-lewis-co-senior-software-engineer-data-platform-foundational-engineering\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fglass-lewis-co-senior-software-engineer-data-platform-foundational-engineering"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":4073913}},{"tool":"search_jobs","arguments":{"company":"glasslewis.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":4073913},"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.
