Migration & Delivery : \n\n- Migrate SQL workloads, transformations, and data models from Snowflake and Spark to Apache Doris.\n\n- Translate Snowflake-specific SQL (semi-structured VARIANT / OBJECT, stored procedures, tasks, streams) and Spark jobs into equivalent, validated Doris SQL.\n\n- Design Doris table models appropriately - Duplicate, Aggregate, and Unique key models - mapping source schemas to the right model for each workload.\n\n- Integrate Apache Iceberg via Doris Multi-Catalog for federated lakehouse querying, and design ingestion paths from Iceberg into native Doris tables where low latency is required.\n\n- Design and implement data-parity validation - schema, row-count, and value-level reconciliation between source (Snowflake/Spark) and target (Doris/Iceberg).\n\n2. Query Engineering & Performance : \n\n- Write, optimize, and troubleshoot complex analytical SQL on Doris (MySQL-protocol compatible).\n\n- Tune query performance : bucketing/partitioning strategy, colocate joins, runtime filters, and the cost-based optimizer.\n\n- Design and maintain materialized views, rollups, and indexes (inverted, bitmap, bloom filter, N-gram) to accelerate queries.\n\n- Analyze query plans (EXPLAIN, profile) and resolve memory pressure, tablet skew, and slow scans.\n\nRequired Skills & Qualifications : \n\n- Hands-on production experience with Apache Doris (or a comparable MPP OLAP engine - StarRocks, ClickHouse, Greenplum).\n\n- Strong, deep SQL expertise - complex analytical queries, window functions, CTEs, query optimization.\n\n- Solid understanding of Doris architecture (FE/BE), the three data models (Duplicate/Aggregate/Unique), partitioning, bucketing, and tablet/replica management.\n\n- Experience with Apache Iceberg (or comparable open table formats - Delta Lake, Hudi) and lakehouse / external-catalog federation.\n\n- Practical experience with Snowflake and/or Apache Spark - enough to read, understand, and migrate existing workloads.\n\n- Understanding of distributed / MPP query execution : join distribution, runtime filters, memory management, and data skew.\n\n- Experience with cloud object storage and columnar file formats (Parquet, ORC).\n\n- Proficiency in at least one programming language (Python, Java, or Scala) for tooling, UDFs, and automation.\n\n- Version control (Git) and CI/CD for data pipelines.\n\nPreferred / Nice-to-Have : \n\n- Experience leading a Snowflake - Doris or Spark - Doris migration at scale.\n\n- Experience building data-validation / reconciliation frameworks for migration parity.\n\n- Knowledge of Doris internals or connector development (custom UDFs/UDAFs).\n\n- Workflow orchestration (Airflow, Dagster) and dbt (with a Doris adapter).\n\n- Data governance, lineage, and cost-optimization tooling.\n\nSoft Skills : \n\n- Strong analytical and problem-solving mindset for debugging correctness and performance issues.\n\n- Clear communication - able to document migration decisions and work with analytics, platform, and business teams.\n\n- Ownership mentality with attention to data correctness and reliability.\nSkills\nData Engineering, OLAP, Data Modeling, Data Pipeline, Data Warehousing, Snowflake DB, Spark, SQL, Python, Java","description_format":"text","description_chars":3671,"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":["IT Consulting & Digital Transformation","IT Staffing & Staff Augmentation"],"lifecycle":[{"event":"open","at":"2026-10-18T01:22:52Z"}],"visa":[],"liveness":{"score":3,"band":"cold","label":"Long shot","p_open":0.4,"p_active":0.295,"p_room":0.28,"age_days":74,"expected_fill_days":24,"reasons":["seen:74","win:tail","crowd:"],"computed_at":"2026-10-19T05:45:15Z"},"pay":null,"html_url":"https://alion.io/job/convergence-consulting-apache-doris-developer-data-engineering","json_url":"https://alion.io/job/convergence-consulting-apache-doris-developer-data-engineering.json","meta":{"generated_at":"2026-10-20T02:33:10Z","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":2850,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-21T00:00:00Z"}},"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":3812568},"rest":"https://alion.io/mcp/rest/get_company?id=3812568"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fconvergence-consulting-apache-doris-developer-data-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%2Fconvergence-consulting-apache-doris-developer-data-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%2Fconvergence-consulting-apache-doris-developer-data-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/convergence-consulting-apache-doris-developer-data-engineering\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fconvergence-consulting-apache-doris-developer-data-engineering"}]}
