Perform query optimization, indexing, connection pooling (e. g., PgBouncer), and resource configuration for low latency and high throughput.\nAnalytical and Secondary Data Stores: Support and manage analytical/OLAP workloads (e. g., ClickHouse) and caching/NoSQL systems (e. g., Redis) as needed.\nAutomation: Automate routine database administration tasks, migration scripts, installation workflows, and configuration management using scripting (Bash/Python) and automation tools.\nSecurity: Implement and maintain database security controls, including hardening, role-based access management (RBAC), auditing, and encryption standards.\nCollaboration and Documentation: Work closely with development, infrastructure, and platform teams to improve reliability, scalability, and schema design while maintaining comprehensive technical documentation.\nRequirements:\nExperience: 5-8 years of hands-on experience in database administration. PostgreSQL.\nExpertise: Expert-level knowledge of PostgreSQL architecture, internals, physical/logical replication, connection pooling (e. g., PgBouncer), and performance tuning is mandatory.\nDatabase Migration: Proven experience migrating schemas, queries, and live data from other relational database engines (e. g., MariaDB/MySQL) to PostgreSQL.\nHigh Availability and Replication: Deep understanding of HA architectures (e. g., Patroni, pg_auto_failover), backup strategies (pgBackRest, WAL archiving), point-in-time recovery (PITR), and replication topologies.\nInfrastructure and Deployment: Proven experience installing and configuring databases in hybrid environments (customer DCs and cloud).\nObservability: Proficiency with monitoring tools, specifically Prometheus and Grafana.\nNice To Have:\nMariaDB / MySQL Expertise: Solid hands-on experience administering, replicating, and tuning MariaDB or MySQL databases.\nRedis and NoSQL: Working knowledge of Redis (for caching and persistence) and general exposure to NoSQL databases.\nAnalytical Databases and Workloads (OLAP): Experience administering columnar or analytical databases (e. g., ClickHouse, Druid, Snowflake, Vertica). Hands-on ClickHouse experience (cluster operations, sharding) is a major bonus.\nIaC Tools: Familiarity with Ansible, Terraform, or Chef for configuration management.\nAutomation: Strong scripting skills in Bash and/or Python for automating installation, migration, and maintenance tasks.","description_format":"text","description_chars":3231,"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":["Power Grid","Low-Code & No-Code Platforms"],"lifecycle":[{"event":"open","at":"2026-09-10T07:06:45Z"}],"visa":[],"liveness":{"score":14,"band":"cold","label":"Long shot","p_open":0.4,"p_active":0.614,"p_room":0.55,"age_days":46,"expected_fill_days":36,"reasons":["seen:46","win:tail"],"computed_at":"2026-10-27T05:46:45Z"},"pay":null,"html_url":"https://alion.io/job/workongrid-database-engineer","json_url":"https://alion.io/job/workongrid-database-engineer.json","meta":{"generated_at":"2026-10-27T11:51:28Z","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":14086,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-28T00:00:00Z"}},"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":1577},"rest":"https://alion.io/mcp/rest/get_company?id=1577"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fworkongrid-database-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%2Fworkongrid-database-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%2Fworkongrid-database-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/workongrid-database-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fworkongrid-database-engineer"}]}
