DEFCON AI is an insights company that leverages artificial intelligence, mathematical optimization, data analytics, and software engineering for resilient optimization of complex systems.\nIn today’s dynamically changing world, DEFCON AI’s technology aligns outcomes with operational goals, better decision making, and empowers customers to anticipate assess, and mitigate the impacts of disruptions.\nIf your answer to “the two records disagree” is never overwrite, this role was built for you. \nAbout the Role \nAs a Senior Data Platform Engineer, you’ll own the durable view of every resolved entity on the platform: the storage layer that holds what we know, where each fact came from, how confident we are in it, and how that picture has changed over time. When two sources disagree, both are kept with their evidence. When someone asks what we believed on a given date, and why, the platform can answer. \nYou’ll join the analytics and AI engineering team behind a system that ingests records from dozens of disparate sources, resolves them to the right entity, highlights what analysts should review first, and provides transparent, explainable recommendations that users can trust. Operating within a secure government cloud environment, the platform depends on a storage layer that never quietly erases a disagreement between sources. \nUpstream matching is probabilistic. A match arrives with a confidence score rather than a yes, and the storage layer carries that uncertainty forward rather than collapsing it into one clean record. Sources change shape without warning and there is no shared key to join on, so this is a current data-engineering problem rather than a classic warehousing one. \nThe seniority this role calls for is about judgment, not tooling breadth: knowing why you never overwrite, and being able to reconstruct a past decision with its evidence a year later. If your instinct when records disagree is to preserve both and let a human decide, you’ll be at home here. \nThis is a fully remote role with occasional travel to DEFCON AI headquarters, customer sites, and partner facilities as needed.\nKey Responsibilities \nDesign and build the storage layer that preserves source disagreement and history rather than resolving them away at write time \nBuild the first release’s result and evidence store: saved per-person results linked to the originating record, prior results and human feedback retained separately, and configuration versions on every result \nImplement provenance and lineage across every node and edge against the platform’s evidence-record contract \nStore the versioned rule library and configuration, and record on every result the exact rule versions and ordered context supplied to any model-assisted step \nEnsure every write is traceable to its origin and every decision is reproducible \nCarry match confidence and other uncertainty forward through the platform rather than collapsing it into a single value \nSupport point-in-time questions: what did we believe about this entity on this date, and on what evidence \nDefine, with entity resolution and ML teammates, what the storage layer needs to receive and what it must serve downstream \nRequired Qualifications \n6+ years in data engineering or data platform engineering, including production experience with versioned, temporal, or historized data models \nExperience designing storage where history, provenance, and source disagreement are first-class rather than resolved away \nComfort building on probabilistic upstream output rather than a clean shared key \nStrong Python and SQL, with production experience on PostgreSQL or comparable \nUS Citizenship Required \nActive US Secret clearance \nPreferred Qualifications \nExperience building the storage layer downstream of an entity-resolution or record-linkage system \nBi-temporal, event-sourced, graph, or temporal data modeling in production \nFederal, government, or regulated-industry experience where a historical decision had to be reproducible on demand \nActive Top Secret clearance \nWhat Success Looks Like \nA durable view that never silently overwrites a disagreement between sources \n“What did we believe on this date, and on what evidence” is answerable a year later \nThe storage layer holds up as probabilistic match output flows in, rather than assuming a clean join \nWhat We Offer \nA fully remote, results-based environment \nCompetitive salary, bonus, and equity package \n100% employer paid, comprehensive health insurance including medical, dental, and vision for you and your family \nUnlimited PTO, with your manager’s approval \nFlexible work environment where you manage your work day \n14 weeks of fully-paid parental leave \nSalary Range: $165,000-$200,000. This represents the typical salary range for this position based on experience, skills, and other factors. \nWe’re an Equal Opportunity Employer: You’ll receive consideration for employment without regard to race, sex, color, religion, sexual orientation, gender identity, national origin, protected veteran status, or on the basis of disability. \nApplicant Data Disclosure \nBy submitting an application, you acknowledge that Defcon AI uses third-party service providers to facilitate its recruitment and hiring processes.
