What We Do
At the SEI AI Division, we conduct research in applied artificial intelligence and the engineering challenges related to building, deploying, and sustaining AI-enabled systems for high-impact government missions.
The Frontier Lab advances AI engineering and transitions frontier AI capabilities to government stakeholders through applied research, rapid prototyping, short-cycle TEVV, and technical advisory.
Position Summary
As a Senior Machine Learning Research Scientist in the Frontier Lab, you will serve as a senior individual contributor and technical leader, shaping and executing applied research and prototype capability development for government and Do W missions. This role spans the research-engineering spectrum: some SR MLRS hires may lean more research-heavy and others more engineering-heavy, but successful candidates collaborate effectively across both.
You will operate with high autonomy, represent technical work with customers and stakeholders, and help guide Frontier Lab research direction—while remaining hands-on in development, evaluation, and delivery. Your work may span Frontier Lab focus areas such as:
-
Agentic AI for mission workflows (e.g., planning, analysis, decision support) where autonomous and human-guided agents interact with tools, data systems, and operators.
-
AI test, evaluation, verification, and validation (TEVV) to improve confidence in performance, robustness, uncertainty, and trustworthiness of ML-enabled systems.
-
Mission-tailored language models, including techniques to improve accuracy and reliability, reduce hallucinations, and integrate structured knowledge for operational tasks.
-
Mission modalities and multimodal learning, including sensor fusion and learning under noisy, sparse, or constrained data conditions (including synthetic data and weakly-/self-supervised approaches).
-
AI at the tactical edge, enabling capability under constrained compute/connectivity through efficient inference, compression, rapid adaptation, and update/redeploy patterns.
Key Responsibilities / Duties
Senior MLRS staff are expected to operate with a high degree of autonomy and technical ownership while remaining hands-on in development, evaluation, and delivery.
-
Mission-context execution : Execute work within the operational context—understanding users, workflows, constraints, success criteria, and outcomes—so technical decisions are grounded in real mission needs.
-
Technical leadership / Tech lead : Lead technical execution by defining technical tasking, sequencing work into realistic milestones, maintaining delivery quality, and delegating appropriately across the team.
-
Applied research and prototyping : Design and run studies, build convincing prototypes and reference implementations, and produce evidence-backed insights that can be matured and transitioned into operational settings.
-
Evaluation, assurance, and evidence : Establish credible evaluation strategies and test pipelines that assess performance, robustness, reliability, and trustworthiness in mission-representative scenarios.
-
Customer-facing technical ownership : Serve as the primary technical interface when appropriate ; translate mission goals into measurable technical outcomes; communicate progress, decisions, and risks clearly to stakeholders.
-
Mentorship and talent development : Proactively mentor junior staff and teammates, raising the bar for research rigor, engineering practice, and delivery habits across project teams.
-
State-of-the-art awareness and agenda shaping : Maintain strong awareness of frontier developments aligned to the Frontier Lab, share insights with the lab, and help shape research directions and future work selection.
-
Self-direction and time management : Manage multiple priorities effectively, sustain steady execution cadence, and resolve blockers with minimal oversight.
-
Community building (internal and external) : Build a strong research culture through internal talks, reading groups, and workshops; and engage with external AI/ML communities (professional societies, consortiums, working groups, and conferences) to strengthen collaboration pathways and keep the lab connected to emerging practice.
Requirements
-
Education / Experience
-
BS in Computer Science, Electrical Engineering, Statistics, or related field with 10 years of relevant experience; OR MS with 8 years of relevant experience; OR PhD with 5 years of relevant experience.
-
Deep expertise in one or more Frontier Lab-aligned areas (agentic systems, LLM reliability/evaluation, CV evaluation, robustness/assurance, TEVV pipelines, multimodal learning, edge ML).
-
Strong engineering capability – can build and maintain high-quality prototypes, evaluation infrastructure, and repeatable experimentation workflows.
-
Strong written and verbal communication skills; able to represent technical work credibly to senior stakeholders.
-
Demonstrated ability to lead technical workstreams and coordinate multi-person execution.
Knowledge, Skills, & Abilities (KSAs)
-
Technical judgment: Makes sound architectural and methodological decisions; balances ambition with mission constraints.
-
Customer translation: Converts mission needs into tractable technical plans, measurable success criteria, and credible evaluation evidence.
-
Scientific leadership: Maintains rigor; identifies flawed assumptions; improves evaluation quality and research practices.
-
Mentorship & influence: Elevates team performance through hands-on guidance and strong technical standards.
-
Initiative: Proactively identifies risks/opportunities, proposes new work, and creates alignment without directive management.
-
Self-direction and time management : Plans work effectively under ambiguity, maintains execution cadence, and escalates risks early.
Desired Experience
-
Leading applied research projects resulting in effective prototypes, mission-relevant evaluation outcomes, or transitioned methods.
-
Publications at strong venues (e.g., NeurIPS / ICLR / ICML, relevant workshops, MLCON), and/or demonstrable impact through applied research artifacts (benchmarks, evaluation suites, open-source, technical reports).
-
Designing and operating TEVV efforts including evaluation pipelines, robustness analysis, calibration/uncertainty work, regression suites, and scenario-based evaluation protocols.
-
Building agentic capabilities integrated with tools, data systems, and human workflows (decision support, planning, analytic contexts).
-
Experience with secure or operational environments and delivery constraints typical of government settings.
-
Experience shaping a technical roadmap or research portfolio aligned to sponsor priorities and lab strategy.
Other Requirements
-
Flexible to travel to SEI offices in Pittsburgh, PA and Washington, DC / Arlington, VA , sponsor sites, conferences, and offsite meetings ( ~10% travel ).
-
You must be able and willing to work onsite at an SEI office in Pittsburgh, PA or Arlington, VA 5 days per week.
-
You will be subject to a background investigation and must be eligible to obtain and maintain a Department of War ) security clearance.
