We’re backed by leading venture capital firms and prominent financial institutions.

This is a hands-on role at a critical moment: we're building our data platform from the ground up, which means high autonomy, direct stakeholder access, and architecture decisions that stick.\nResponsibilities\nOwn the data development process end-to-end: business understanding, design, implementation, QA, and production maintenance.\nDesign, build, and operate our cloud data platform - ingestion pipelines, streaming and batch processing, and a structured analytical layer serving Risk, Finance, Product and other stakeholders.\nConsolidate diverse data sources (internal databases, external FX rate feeds, bank files, third-party APIs) into a governed, reliable analytical layer.\nImplement and maintain CI/CD, observability, and infrastructure-as-code practices - DEV/QA/PROD parity, pipeline monitoring, alerting on data quality issues before the business notices them.\nBuild the foundations of an ML feature platform, enabling data scientists to focus on modeling rather than pipeline plumbing.\nEnsure data quality and integrity across ETL processes - owning what happens when checks fail, not just that they run.\nCollaborate with analysts, data scientists, and business stakeholders to translate business requirements into data models and pipeline logic.\nRequirements\n5+ years hands-on experience as a Data Engineer on AWS.\nStrong Python and SQL - clean, testable, production-grade code.\nProven experience building and operating data pipelines using DMS, Glue, and Airflow (MWAA).\nReal streaming experience - Kinesis or Kafka in production, not just local setup. Knows what consumer lag means and how to debug it.\nExperience with CDC architectures and schema evolution challenges in production environments.\nExperience with Snowflake or a comparable analytical database.\nSolid understanding of data modeling, cloud cost awareness, and performance tuning.\nStrong problem-solving instincts: can work with ambiguous requirements, makes reasonable decisions and documents them.\nGood communicator - comfortable talking directly to non-technical stakeholders.\nAdvantage\nApache Iceberg in production (schema evolution, compaction, time travel).\nExposure to financial data domains - FX, treasury, trade reconciliation.\nExperience with dbt for transformation layer modeling.\nFamiliarity with Terraform for infrastructure-as-code.\nComfortable leveraging AI development tools such as Cursor, Claude Code, or GitHub Copilot to improve engineering productivity.","description_format":"text","description_chars":3065,"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":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Blockchain & Crypto","Commerce","Financial Services"],"lifecycle":[{"event":"open","at":"2026-10-17T04:58:55Z"}],"visa":[],"liveness":{"score":40,"band":"fade","label":"Fading","p_open":1,"p_active":0.734,"p_room":0.55,"age_days":29,"expected_fill_days":28,"reasons":["conf:2","win:tail"],"computed_at":"2026-10-24T06:02:35Z"},"pay":null,"html_url":"https://alion.io/job/grainfinance-data-engineer","json_url":"https://alion.io/job/grainfinance-data-engineer.json","meta":{"generated_at":"2026-10-24T11:47:26Z","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":16865,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-25T00:00:00Z"}},"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":3809738},"rest":"https://alion.io/mcp/rest/get_company?id=3809738"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fgrainfinance-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%2Fgrainfinance-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%2Fgrainfinance-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/grainfinance-data-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fgrainfinance-data-engineer"}]}
