What the occupation pays Median $166,452 (middle half $130,866–$200,954).

Estimated from BLS employment for this occupation and area, per-skill prevalence across our listing corpus, and published wage benchmarks — as of Aug 3, 2026. It is a model, not a headcount.

Why we read it this way (6)

The posting lists relational RDBMS options (PostgreSQL, Oracle, SQL Server) and graph DB options (Neo4j, Amazon Neptune, Stardog, GraphDB) as interchangeable alternatives within each category — both categories are hard-gated requirements. Because any one option from each group satisfies the requirement, they are grouped with alternatives accordingly.

Degree requirement: the JD offers two paths — an advanced degree with 12 years of experience, or a bachelor's degree with 17 years. Neither degree is strictly required on its own (experience can substitute), so the degree requirement is set to None; the overall years minimum reflects the lower bound of 12 years.

The role title contains a typo ('Sneior') in the body text but is clearly intended as 'Senior Database Engineer'.

Stardog and GraphDB appear only within a parenthetical list of graph DB examples alongside the primary options Neo4j and Amazon Neptune; they are captured as preferred alternatives rather than independent hard gates.

No compensation information is provided in the posting.

Requires a TS/SCI clearance — the cleared population is a small fraction of this occupation, so the real candidate pool is materially smaller than the estimate below, which does not model clearance.
