Please see details below:\nAbout the Role\nPrincipal Data Architect, Data Platform and Pipelines\nBabel Street is hiring a hands-on architect to redesign and rebuild Babel Street's data infrastructure and pipelines. You will set the target architecture, write the critical code yourself, and lead engineers through a multi-year move of a petabyte-scale platform onto Google Cloud.\nBabel Street collects, enriches and resolves open-source and commercial data across hundreds of sources and dozens of languages. Today that data flows through pipelines and stores that grew up separately: a mix of warehouse, search and object storage, plus legacy delivery systems that are hard to change and expensive to run. Your job is to replace that with one coherent platform that is cheaper, more reliable, and built for AI and agentic workloads.\nThis is a principal engineering role, not a people-management role. You will be judged on the systems you design and ship, the quality of your technical decisions, and how much you raise the bar for the engineers around you. You will report to the SVP of Engineering and work alongside their Head of Architecture, AI, Graph and Product teams.\nAbout the Company\nBabel Street is the trusted technology partner for the world’s most advanced identity intelligence and risk operations. They deliver advanced AI and data analytics solutions providing unmatched, analysis-ready data regardless of language, proactive risk identification, 360-degree insights, high-speed automation, and seamless integration into existing systems. Babel Street empowers government and commercial organizations to transform high-stakes identity and risk operations into a strategic advantage. The actionable insights we deliver safeguard lives and protect critical assets around the world. Babel Street is headquartered in Reston, Virginia, with regional offices in Boston, MA and Cleveland, OH, and international offices in Australia, Canada, Israel, Japan, and the U.K.\nWhat you will do in your first year:\nIn your first 90 days, map the current estate end to end: every source, pipeline, store, consumer and delivery path, with its volume, cost, owner and failure history. Publish a target-state data architecture and a sequenced migration plan that engineering and product leadership sign off.\nDesign and build the new ingestion and processing backbone. Replace bespoke pipelines with a standard pattern for streaming and batch ingestion, enrichment, and delivery, running at millions of documents per day with clear SLOs.\nLead the data platform workstream of our GCP migration. Turn \"lift and shift\" into real modernization: decide what moves as is, what gets rebuilt, and what gets retired, and own the technical design of each wave.\n Rationalize storage and search. Define when we use the warehouse (BigQuery), search and index (Elasticsearch/OpenSearch), object storage, vector and graph stores, then consolidate toward that pattern and cut the cost of our most expensive workloads.\n Build the data foundation for AI. Deliver agent-callable data services, hybrid retrieval (keyword, analytical, vector, graph), and provenance and lineage on every record so our AI products can cite their evidence.\n Build the governance and compliance platform. Centralize and serve governed and compliant data (e.g. privacy laws) as part of AI-readiness, setting parameters, exclusions, and retention for optimal performance of AI.\nMake the platform operable. Put in place data contracts, quality checks, observability and cost attribution so every pipeline has an owner, an SLO and a known unit cost.\nWhat you will own:\n Pipelines and ingestion. Architecture and reference implementations for collection, ingestion, parsing, enrichment (translation, NER, entity resolution) and delivery. Event-driven and queue-based processing, idempotency, backfills and replay, schema evolution, and exactly-once or effectively-once guarantees where they matter.\nStorage, compute and search. The physical data platform across warehouse, lakehouse, search and object storage. Partitioning, indexing, tiering and retention strategies at petabyte scale. Query and aggregation performance, and the hardware and cost trade-offs behind them.\nCloud migration and environments. Technical design for moving data workloads from AWS to GCP with minimal disruption to customers. Patterns that also work in FedRAMP, disconnected and air-gapped deployments, where managed cloud services may not be available.\nRetrieval and AI enablement. APIs and query layers that serve both analysts and agents. Hybrid retrieval across structured, unstructured, vector and graph data, built with our AI and Graph teams to support RAG and agentic workflows.\nData quality, lineage and economics. Data contracts, automated quality checks, lineage and provenance, observability and SLOs. Unit economics for the platform: cost per source, per pipeline, per query and per customer.\n Technical leadership. Architecture decision records, design reviews and coding standards for data engineering. Mentoring senior engineers, partnering with our offshore engineering teams, and being the escalation point for the hardest data incidents.\nRequired Qualifications:\n12+ years building data systems, with at least 5 as the lead architect or principal engineer on a large-scale data platform.\nYou still write production code. Strong in Python plus at least one of Java, Scala or Go, and fluent in SQL.\nYou have personally led a major re-architecture or cloud migration of a data platform and can walk us through the design, the sequencing, what broke and what you would change.\nDeep hands-on experience with distributed processing and streaming, for example Spark, Beam/Dataflow, Flink, Kafka, Pub/Sub or Pulsar.\nProduction experience with GCP data services such as BigQuery, Dataflow, Pub/Sub, GCS and Spanner. AWS experience is also expected, since you will be migrating from it.\nExpert-level operation of search and index systems (Elasticsearch or OpenSearch) at scale, including cluster sizing, mappings, aggregation performance and cost tuning.\nExperience with lakehouse table formats (Iceberg, Delta or Hudi) and orchestration (Airflow/Composer, Dagster or similar).\nA track record of cutting platform cost materially without hurting performance, and the numbers to show for it.\nClear written communication. You can write a design doc that a CEO and a senior engineer both understand.\nAbility to obtain a US security clearance\nPreferred Qualifications:\nExperience with vector search, embeddings pipelines and retrieval architectures for LLM and agentic applications.\nExperience with entity resolution, knowledge graphs or graph databases, ideally across multilingual or messy real-world data.\nBackground in OSINT, national security or law enforcement, risk intelligence, and financial data\nExperience building for FedRAMP, IL5 or air-gapped environments, including running data platforms without managed cloud services.\nExperience with data observability, lineage and governance tooling (for example OpenLineage, Great Expectations, Monte Carlo, Dataplex).\nExperience combining large volumes of scraped multimedia and structured third-party data.","description_format":"text","description_chars":7271,"description_truncated":false,"requirements":{"experience_years_min":12,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Recruiting & Staffing"],"lifecycle":[{"event":"open","at":"2026-11-04T22:52:53Z"}],"visa":[],"liveness":{"score":54,"band":"ok","label":"Likely open","p_open":1,"p_active":0.542,"p_room":1,"age_days":2,"expected_fill_days":94,"reasons":["conf:2","agency","velocity","win:early"],"computed_at":"2026-11-07T05:47:08Z"},"pay":{"stated_usd_annual":250000,"is_top_pay":true},"html_url":"https://alion.io/job/hatch-it-principal-data-architect","json_url":"https://alion.io/job/hatch-it-principal-data-architect.json","meta":{"generated_at":"2026-11-07T16:27:51Z","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":23242,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-08T00:00:00Z"}},"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":8997},"rest":"https://alion.io/mcp/rest/get_company?id=8997"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fhatch-it-principal-data-architect"},{"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%2Fhatch-it-principal-data-architect"},{"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%2Fhatch-it-principal-data-architect"},{"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/hatch-it-principal-data-architect\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fhatch-it-principal-data-architect"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3774674}},{"tool":"search_jobs","arguments":{"company":"hatchit.io","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3774674},"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.
