The COMSEC Material Control System is an authoritative record of what cryptographic material exists, who holds it, where it moved, and when it was destroyed. You will keep that system running today and design, build, and deploy its replacement.\nThe role runs on two tracks on purpose. Accountability does not pause for modernization, and the hardest part of the new build is not the new schema - it is understanding what is in the legacy record well enough to carry it forward without losing a transaction. You will do both, which is why this job develops a skill set the market is short of.\nWhat You Will Do:\nOperate the current CMCS database and application in production - availability, backup and recovery, performance tuning, patching, and release deployment.\nDesign the Next-Generation CMCS data model: inventory, accounts, custodian and hand receipt chains, chain-of-custody history, destruction records, and access authorizations.\nBuild a tiered architecture that separates data by classification and by audience, with access enforced at the row level in the database rather than only in the application.\nImplement an append-only audit architecture where every accountability event carries actor, timestamp, and source, and corrections are new entries rather than overwrites.\nDevelop database services and APIs, managed through version control, peer review, and versioned schema migrations in a CI pipeline.\nIntegrate CMCS with the systems that generate COMSEC events, including Key Management Infrastructure and federal access management systems supporting personnel onboarding and offboarding.\nMigrate the legacy record - profile it, design the transformation rules, and prove record count, balance, and transaction history parity through automated reconciliation before cutover.\nProvide Tier II and Tier III application support, resolving data errors, failed transactions, and reported discrepancies.\nWhy This Role: This is a system of record being rebuilt, not a maintenance seat. You will make the data architecture decisions, then live with them through migration and into production - and few engineers anywhere combine modern data platform skill with real cryptographic accountability depth. There is a defined path toward Senior Database Engineer, CMCS Solution Architect, and engineering leadership.\nRequired Education & Experience:\nBachelor’s degree in a technical discipline and 9 years of experience; Masters and 7 years; 4 additional years of relevant experience may substitute for the degree.\n\n5 years of database engineering or development experience.\n\nProven relational data modeling for transactional systems of record - normalization, referential integrity, constraint design, and audit trail architecture.\n\nProduction DBA experience on an enterprise platform (Oracle, SQL Server, or PostgreSQL): backup and recovery, performance tuning, index and query optimization, high availability.\n\nAdvanced SQL and stored procedure development, plus one general-purpose language for data services and automation.\n\nExperience building system-to-system interfaces - API, message-based, or ETL - with real error handling and reconciliation.\n\nHands-on legacy data migration experience: profiling, transformation design, and proving the migration was complete and accurate.\n\nWorking knowledge of federal database security requirements - access control, encryption, audit logging, and the evidence an Assessment and Authorization needs.\n\nRequired Clearance:\nUS Citizenship.\n\nActive top secret clearance with SCI eligibility.\n\nNice to Have:\nExperience with CMCS, KMI, or another cryptographic accountability system.\n\nExperience building systems that must produce defensible audit evidence under external inspection - property, custody, controlled substances, or financial accountability all count.\n\nMulti-level or compartmented data architectures where classification or need-to-know is enforced in the data tier.\n\nNear real-time dashboards and reporting against a transactional system without degrading transaction performance.\n\nFamiliarity with COMSEC accountability concepts: CCI handling, hand receipts, SF-153 transfers, inventory reconciliation, destruction reporting.\n\nAgile delivery with JIRA and CI pipelines in a federal accredited environment; ServiceNow ITSM and CMDB.","description_format":"text","description_chars":4444,"description_truncated":false,"requirements":{"experience_years_min":9,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":true,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Digital Government","Systems Integrators","Engineering Services"],"lifecycle":[{"event":"open","at":"2026-10-31T16:02:22Z"}],"visa":[],"liveness":{"score":63,"band":"ok","label":"Likely open","p_open":1,"p_active":0.632,"p_room":1,"age_days":3,"expected_fill_days":24,"reasons":["conf:9","stale_co","velocity","win:early","comp:brand"],"computed_at":"2026-11-01T06:10:25Z"},"pay":null,"html_url":"https://alion.io/job/saic-comsec-database-engineer","json_url":"https://alion.io/job/saic-comsec-database-engineer.json","meta":{"generated_at":"2026-11-01T09:08:28Z","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":14132,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-02T00:00:00Z"}},"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":58788},"rest":"https://alion.io/mcp/rest/get_company?id=58788"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fsaic-comsec-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%2Fsaic-comsec-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%2Fsaic-comsec-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/saic-comsec-database-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fsaic-comsec-database-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3570320}},{"tool":"search_jobs","arguments":{"company":"saic.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3570320},"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);
