Belay Technologies has been voted Baltimore Business Journal's (BBJ) Best Places to Work 2026!
 
Belay Technologies is seeking a Senior Software Engineer to join our intel team. AIMASSIST brings AI into the operations organization, embedding engineers with the operators, analysts, and developers who carry out the CNO mission. Our engineers learn how those teams work, find the tasks that consume their time, and build AI agents and tools that let them move faster without giving up accuracy or control. We build on both frontier models and on-premises open-weight models, served through the customer's enterprise AI platform, and turn them into mission capabilities such as agents that triage incoming data, automate repetitive tradecraft, or research across disparate sources on an analyst's behalf. We are now introducing autonomous agents the mission can trust: agents that take real actions within guardrails, are measured against evaluations built with the people who use them, and log every step so a reviewer can follow what they did. As a senior Applied AI Engineer, you will lead forward-deployed work with a mission customer from the first conversation through production and set the technical direction for the agents your team builds. You will mentor engineers who are newer to applied AI and help define how our team develops software with AI, including the review standards and validation layers that let us put autonomous coding agents to work on mission code. This role suits an experienced engineer who wants to shape how AI is fielded across operations and grow into project leadership.

Responsibilities:
  • Lead forward-deployed engagements with operations customers: elicit requirements from operators and analysts, identify the workflows where AI saves the most time, and deliver solutions from prototype to production.
  • Architect and build agentic systems in Python that connect LLMs, MCP servers, Skills, and subagents to mission data sources and existing operational tools.
  • Design guardrails for autonomous agents, including scoped permissions, human approval gates, and audit logging, so agents can act on operational systems safely.
  • Build evaluation suites with mission users that measure the accuracy, reliability, and failure modes of AI capabilities, and use the results to decide when a capability is ready to field.
  • Evaluate new models, frameworks, and AI design patterns, both frontier and open-weight, for fit against mission problems, and brief findings and tradeoffs to technical and government leadership.
  • Use AI coding agents (e.g., Claude Code) in daily development, and help define team standards for reviewing, testing, and validating AI-generated code.
  • Mentor engineers through design reviews, code reviews, and pairing, and lead technical design discussions for your project area.
  • Communicate progress, risks, and tradeoffs to project leads and government stakeholders.

Candidates should have the following qualifications: 
  • TS/SCI Clearance with polygraph
  • 12 yrs., B.S. in a technical discipline or 4 additional yrs. in place of B.S.

Skills Requirements:
  • Extensive professional software engineering experience with advanced Python proficiency, including production services, APIs, and data pipelines that users depend on.
  • Experience building LLM applications or agentic systems that use tool/function calling, structured outputs, context management, and multi-step workflows.
  • Experience working directly with end users or mission customers to turn ambiguous operational problems into delivered software.
  • Experience designing tests, evaluations, or validation layers for AI or other non-deterministic systems.
  • Experience using AI coding assistants or agents (e.g., Claude Code, Codex, Copilot) for code generation, refactoring, and debugging, with the review discipline to own and explain everything they produce.
  • Technical leadership experience, such as serving as tech lead, leading design decisions, or mentoring engineers.
  • Experience with Git, CI/CD pipelines (GitLab preferred), Docker/Kubernetes, and Atlassian tools (Jira, Confluence).
  • Strong written and verbal communication with technical and non-technical audiences.

Candidates are desired to have the following skills:
  • Experience with Model Context Protocol (MCP), Skills, subagents, or multi-agent orchestration frameworks such as PydanticAI or LangGraph.
  • Experience securing LLM applications against prompt injection, data leakage, and over-permissioned tool access.
  • Experience with retrieval systems (RAG, vector databases, Elasticsearch).
  • Experience building spec-driven or autonomous development pipelines with AI coding agents.
  • Prior forward-deployed or embedded customer-facing engineering experience.
  • Experience with production CNO capabilities and operations, or knowledge of end-to-end SIGINT collection and analysis systems.

Perks and Benefits:
  • 8 weeks paid leave - 4 weeks of personal leave, 3 Yay! days, take off on your birthday,11 paid holidays and optional leave up to 6 days through Belay's volunteer program
  • 10% matching in 401(k) contributions vested on day one
  • $5,000 annual training/tuition
  • Student Loan Repayment Program
  • 100% company-funded HSA
  • Rich medical coverage (100% coinsurance)
  • Dental coverage including orthodontia
  • Up to $420,000 in life insurance, premiums 100% company funded
  • Amazon Prime, gym reimbursement, monthly lunches, games and prizes
  • Pet adoption program, generous referral bonus program, fun events, and more!

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
