Software Engineer (SWE), Level 3

An active TS//SCI clearance with polygraph is required for this role

Hey!

Bitwise is a leading provider of mission-focused intelligence solutions that advance national security for the Intelligence Community and Department of Defense. We're a small and growing company, so you can expect to hop in on the ground floor with us and be a consequential member of the team. You'll be more than a contract performer for us — you'll also be asked for ideas to improve our company and improve your career, and you'll contribute to our team culture. We value growth and community above almost all else, so we gather regularly for game nights, happy hours, tech talks, and plenty more. We think you'll like it here!

Remember, Bitwise is not a cult.

What We Look For

Bitwise hires talented engineers who are driven by purpose and who value a culture of technical excellence, growth, and overall wellness. We deliver new and innovative intelligence solutions to our customers at the very forefront of our country's national security missions. And we do it every single day. Our work matters, and so will you.

We ask that every new hire be able to:

• Contribute meaningful thought leadership — if not right away, over time
• Interact with our customers and earn their confidence in your abilities
• Be detailed, even if that means taking a little more time to get it right
• Contribute their ideas and ideals to improve all aspects of our company
• Allow us to invest in their education so we both grow together
• Know and live our core values every single day

About this Role

We're looking for an experienced Software Engineer to lead forward-deployed work with our mission customers, taking AI from concept through production. You'll work directly with operators and analysts to understand their workflows, identify where AI can save them time, and build agentic systems that deliver real operational value.

As a senior engineer on our team, you'll architect and build sophisticated AI agents in Python that connect large language models, data sources, and operational tools. You'll design the guardrails that let autonomous agents act safely within operational systems—scoped permissions, human approval gates, audit logging—so we can put powerful AI to work without sacrificing control or accountability. You'll partner with mission users to build evaluation suites that measure accuracy, reliability, and failure modes, and you'll use those results to decide when a capability is ready to field.

You'll also shape how our team develops with AI. You'll use AI coding agents in your daily work, help define team standards for reviewing and validating AI-generated code, and mentor engineers through design reviews, code reviews, and pairing. You'll evaluate new models and frameworks—both frontier and open-weight—against mission problems, and brief findings and tradeoffs to technical and government leadership. This role suits an experienced engineer who wants to influence how AI is fielded across operations and grow into project leadership.

Requirements

• 12+ years of relevant experience with a B.S. in a technical discipline, or 16+ years of relevant experience without a degree
• 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

Preferred 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
