Built for the AI era, Saviynt helps organizations move faster - securely and compliantly.\nABOUT THE ROLE\nYou set the architectural direction for how training data flows, evolves, and is governed across the AI Platform. You define the standards ML engineers and scientists build on, and ensure every training signal is tenant-isolated, PII-free, and traceable from source to model.\nWHAT YOU'LL OWN\nAI Data Lake on GCS: bucket layout, raw → silver → gold tier separation, CMEK encryption, lifecycle rules\n\nBatch pipelines: Spark on Dataproc for TB-scale feature backfills, Iceberg compaction, and daily S3→GCS incremental sync\n\nStreaming pipelines: Apache Beam on Dataflow for sub-5-min CDC ingestion with exactly-once semantics and PII assertion gates\n\nSchema registry: Avro / Protobuf schema versioning, compatibility modes, and migration playbooks for safe schema evolution\n\nOrchestration: Flyte as primary DAG layer - task authoring standards, domain isolation, retry policies, DataCatalog memoization; evaluate Kubeflow Pipelines where relevant\n\nMulti-tenancy: strict per-tenant GCS prefix isolation, quota policies, and cross-tenant contamination validation\n\nData Anonymizer and Data Labeler microservices: strip PII and attach ML labels before signals leave each customer environment\n\nFeature store: Feast offline (GCS Parquet) and online (Redis) with point-in-time correctness and < 0.1% consistency SLA\n\nVector database: operate Pgvector (Cloud SQL) for POC and Qdrant on GKE for production-scale embedding storage; design index strategies (IVFFlat, HNSW) and manage ANN query latency SLAs\n\nRAG data pipeline: build embedding generation pipelines that chunk, encode, and upsert document embeddings into the vector store; own the data refresh cadence and staleness SLAs for retrieval context\n\nService APIs: expose data platform services (feature serving, embedding upsert, schema validation) over HTTPS with mTLS and gRPC where low-latency streaming is required\n\nSynthetic data pipelines for dev/staging where real customer data is not permitted\n\nData quality gates: Great Expectations / dbt checks as Flyte tasks, blocking on schema and PII-absence failures\n\nYOU'LL THRIVE HERE IF YOU HAVE\n1+ years of experience as a Principal SWE at a SaaS company\n\nDemonstrated principal impact: platform standards you defined adopted org-wide, or major cross-team pipeline/schema migrations you led\n\nData lake ownership (essential): you have designed and operated a production data lake end-to-end - storage layout, partitioning strategy, tiered retention (hot/warm/cold), table format (Iceberg or Delta Lake), compaction, and access control; not just consumed one\n\nDeep Spark (PySpark / Scala): executor tuning, shuffle diagnosis, Iceberg table maintenance\n\nHands-on Beam / Dataflow: windowing, exactly-once, side inputs, autoscaling\n\nSchema registry experience: Protobuf / Avro compatibility rules, breaking-change migrations in production\n\nOrchestration at scale: Flyte, Kubeflow Pipelines, Airflow, or Prefect - operated in production, ideally benchmarked two\n\nMulti-tenant data architecture: per-tenant isolation as a hard requirement, not a post-hoc concern\n\nFeature store operations: Feast or Tecton, point-in-time joins, online/offline consistency\n\nVector databases: Pgvector or Qdrant in production - index tuning, ANN search, embedding upsert pipelines\n\nRAG data fundamentals: chunking strategies, embedding model selection, retrieval quality evaluation, and context freshness management\n\nAPI transport: gRPC and HTTPS/mTLS for service-to-service communication; comfortable defining proto contracts and managing certificate lifecycle\n\nBachelor's degree in Computer Science, Engineering, or a related field, or equivalent practical experience or equivalent military experience\n\nNICE TO HAVE\nDifferential privacy or k-anonymity for ML training datasets\n\nOpen source contributions: Feast, Great Expectations, Apache Beam, or dbt\n\nFamiliarity with IAM / access governance data: entitlements, provisioning events, access graphs\n\nIceberg or Delta Lake at petabyte scale\n\nWHY JOIN SAVIYNT\nWork on a large-scale, Kubernetes-based SaaS platform\n\nSolve challenging cloud and reliability problems at scale\n\nCollaborate with strong engineers in a reliability-focused culture\n\nCompetitive compensation, benefits, and growth opportunities\n\nSECURITY & COMPLIANCE\nThis role requires adherence to Saviynt's information security and privacy policies, including annual security training.","description_format":"text","description_chars":4692,"description_truncated":false,"requirements":{"experience_years_min":1,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":["Growth opportunities"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Identity Management","Security Compliance"],"lifecycle":[{"event":"open","at":"2026-04-28T21:37:52Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 73 · green card filings: 16","filings_12m":73,"filings_prev_12m":80,"green_card_filings_12m":16,"median_offered_wage_usd":131601,"route":null,"cap_exempt":false,"checked_at":"2026-10-15T11:24:14+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)","US Department of Labor: PERM disclosure data (green cards)"],"filings_for_role_12m":49}],"liveness":{"score":33,"band":"fade","label":"Fading","p_open":1,"p_active":0.741,"p_room":0.44,"age_days":171,"expected_fill_days":151,"reasons":["conf:1","win:tail","crowd:"],"computed_at":"2026-10-17T05:46:00Z"},"pay":{"stated_usd_annual":304000,"is_top_pay":true},"html_url":"https://alion.io/job/saviynt-principal-software-engineer-ai-platform-engineering","json_url":"https://alion.io/job/saviynt-principal-software-engineer-ai-platform-engineering.json","meta":{"generated_at":"2026-10-18T04:59:08Z","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":7555,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-19T00:00:00Z"}},"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":5841},"rest":"https://alion.io/mcp/rest/get_company?id=5841"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fsaviynt-principal-software-engineer-ai-platform-engineering"},{"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%2Fsaviynt-principal-software-engineer-ai-platform-engineering"},{"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%2Fsaviynt-principal-software-engineer-ai-platform-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/saviynt-principal-software-engineer-ai-platform-engineering\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fsaviynt-principal-software-engineer-ai-platform-engineering"}]}
