About the role

Vannevar builds an agentic system that helps operators make sense of high-volume mission data and act with greater speed and confidence in sensitive government environments. The system analyzes millions of mission-relevant records to surface high-fidelity recommendations, near-real-time analysis, and decision-ready outputs while integrating into the systems and workflows customers already use.

Our software is designed to augment, not replace, human judgment. Operators remain in control of consequential decisions, with the system helping them understand evidence, investigate recommendations, and move faster with better information.

In this role, you will help expand the product to new missions, datasets, and operating environments. You will work directly with users and technical stakeholders to understand the mission, decide what should be built, and then build and deploy it. The team moves quickly — the first version of this system was deployed to in nine days — while holding a high bar for reliability, security, and usefulness to the people doing the mission.

This is a senior individual contributor role with broad ownership. You will write code, make architectural and product decisions, navigate complex government technical environments, and own outcomes from an initial mission need through production deployment and continued use.

What you’ll do

• Own mission problems end-to-end: understand the user and workflow, determine what good looks like, design the technical approach, build it, deploy it, and own the outcome
• Architect, build, and own the direction for a product deployed directly to customer environments in support of mission-critical use cases
• Work directly with users and senior technical stakeholders to understand mission needs, constraints, existing systems, and where software can have the greatest impact
• Own end-to-end technical delivery for new mission workstreams, from requirements gathering and system design through implementation, deployment, and sustainment
• Write substantial production code across the stack and improve the product's capabilities, performance, and scalability
• Collaborate with cross-functional partners — including engineers, product designers, and mission domain experts — to plan and deliver complex software features
• Support government-facing technical artifacts as needed, including input to RFIs, RFPs, Statements of Work, and white papers
• Navigate and integrate with government IT ecosystems, ensuring solutions meet security, compliance, and operational constraints
• This role is remote-friendly, but traveling is required - travel up to 50% to engage directly with mission owners and deliver capabilities in the field

What you should have

• 5+ years as a Full Stack Developer including familiarity with relational databases (like Postgres), caching technologies (like Redis), object storage systems (like S3), and modern front-end frameworks (like React)
• Strong technical judgment and the ability to own ambiguous problems without waiting for a fully specified set of requirements
• Experience developing and deploying software compliant with DoD Risk Management Framework (RMF)
• Experience interfacing with government owned IT systems (for example, data platforms, IdAM providers, SIEM, CDSs, etc)
• Experience working with government IT and program offices to scope technical requirements, architecture, and integrations
• Experience working with end users to scope mission requirements, conduct user testing, and gain product feedback
• Excellent communication and teamwork skills
• Must hold an active U.S. TS Security clearance with SCI Eligibility

What we offer

• Health, dental, and vision insurance
• Remote friendly with WeWork access
• Unlimited PTO, shared downtime during the federal holiday calendar, and company-wide off time at the end of each year
• 401(k) match
• Lifestyle & wellbeing stipends
• Salary top-up during military reserve duty
• Fully paid parental leave
• Child and pet care reimbursement during travel
