Наша компания

Red Cell Partners is an incubation firm building and investing in rapidly scalable technology-led companies that are bringing revolutionary advancements to market in three distinct practice areas: healthcare, cyber, and national security. United by a shared sense of duty and deep belief in the power of innovation, Red Cell is developing powerful tools and solutions to address our Nation’s most pressing problems. ABOUT DEFCON AI RESILIENCE IN THE FACE OF DISRUPTION. DEFCON AI is an insights company that leverages artificial intelligence, mathematical optimization, data analytics, and software engineering for resilient optimization of complex systems. In 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.

Чем предстоит заниматься

As a Data & ML Engineer you will build the data and model layer behind an AI-enabled decision-support system operating inside an accredited environment. That work covers ingestion from many source systems, resolution of incoming records against a shared data model, relevance scoring, and generation of explanations a user can act on and defend

Three characteristics make this a substantial technical challenge. The incoming data is predominantly low-signal, which means a model can report strong overall accuracy while failing on the cases that matter most. Every output must remain traceable to the underlying sources, because a person downstream is accountable for the result. Record matching is probabilistic rather than exact, so false matches and missed matches both carry meaningful cost

You will not be starting from an empty repository. We operate an established platform for source custody, extraction, and retrieval, and its architect is a member of this team, so existing design decisions are documented and accessible. Your work will focus on new capability rather than maintenance: record matching, calibrated scoring, and grounded generation, hardened for the target environment. We build with current tooling and expect the same, including the use of AI assistance in our own engineering practice

This is a fully remote role with occasional travel (up to 25%) to DEFCON AI HQ, customer sites, and vendor facilities as required

The technical work falls into four areas. Deep expertise in all four is not expected, so please indicate where your depth lies when you apply. The engineering standards that follow apply to everyone on the team

Design and maintain the graph of entities, records, and the typed relationships between them

Implement probabilistic matching, including blocking, candidate generation, pairwise scoring, clustering, and threshold policy

Build deduplication and known-record suppression

Establish provenance so that every node and edge traces to the source that asserted it

Produce interface and data-flow design documentation detailed enough to serve as an implementation reference for other engineers

Develop relevance and priority models over large, imperfect record sets

Own calibration and threshold design, establishing what a score means rather than only how it ranks

Design abstention policy that routes uncertain and high-risk cases to a person rather than returning a confident answer

Perform feature engineering, establish baselines before introducing complex models, and conduct error analysis that accounts for the differing cost of false positives and false negatives

Implement embeddings, vector storage, and retrieval across a large provenance-tracked evidence base

Integrate language models through an approved managed service, and maintain a self-hosted or open-weight alternative within the same boundary

Design prompts and output schemas

Bind generated text to cited source records, and treat "insufficient evidence" as a valid system response rather than forcing a conclusion

Own model packaging, serving, versioning, and rollback

Build secure ingestion, transformation, validation, and publishing across structured, semi-structured, and unstructured sources

Implement quality checks, schema validation, lineage capture, and audit logging

Establish source drift detection so that degradation is surfaced rather than carried into the analysis

Generate statistically representative synthetic data so that development can proceed ahead of live data access

Наши требования

5+ years of experience in data engineering, data architecture, applied machine learning, ML engineering, or production analytics engineering

Strong Python and SQL, with demonstrated experience working with large, imperfect operational data

Experience delivering systems for sustained operational use rather than exploratory analysis alone

Routine use of AI-assisted development, with informed judgment about where it adds value and where its output requires verification

Ability to explain a technical decision to a stakeholder who must defend that decision without understanding its internals

US Citizenship Required

Active US Secret clearance. The work is performed in a controlled government cloud environment and requires a favorable investigation and CAC eligibility from the start

Elevated personnel security requirements apply to portions of this work and are discussed during screening

Willingness to travel up to 25% to customer sites, DEFCON AI HQ, and vendor facilities as required

Clearance: active Top Secret

Matching: direct experience applying probabilistic matching to inconsistent identity data, including names, dates, addresses, and identifiers, and familiarity with the failure modes of each. Record linkage, master data management, or identity management. Graph data modeling. PostgreSQL and pgvector or comparable. Graph algorithms applied in production

Modeling: model calibration and threshold design. Cost-sensitive learning where error types carry unequal consequences. scikit-learn, XGBoost, PyTorch

Retrieval and generation: retrieval-augmented generation in production. Prompt and output-schema design. Establishing that generated output remains grounded in its sources, and testing to confirm it. Self-hosted or open-weight model operation. Fine-tuning, adapters, or custom embeddings

Pipelines: AWS Glue, Airflow, dbt, Spark, Kafka, or NiFi. Unstructured and semi-structured document ingestion. Synthetic or representative test data generation

Environment: federal DevSecOps, RMF, ATO, or DoW cloud environments. Hardened base images. Experience advancing a pipeline from development through accreditation and deployment

Domain: sensitive federal or defense data, and work performed under privacy or comparable handling constraints

Responsible AI: documentation, model cards, fairness testing, and model monitoring. NIST AI RMF or comparable practice
