About the role

At Vannevar we’re consistently iterating on AI-enabled software products to deter our adversaries and lead the fight for strategic competition. This often involves meeting our customers where they’re at - on government networks, higher classification systems, and bespoke deployments. Compliance and security are core principles in how we build software to support the warfighter.

We’re seeking an experienced Software Engineer who can work across the stack, while also providing expertise in DevOps, security, and compliance. An ideal member of the team has previously helped move a software system to a government/DoD environment, can work quickly in complex environments, and has great communication skills.

What you'll do

Own the technical roadmap and execution plan to achieve successful deployment of a key product suite to a government authorized system.

Design, build, and harden our product suite within a compliant cloud environment.

Work cross-functionally across product teams to help align timelines and develop solutions hands-on to meet security controls.

Implement strong change control: security impact analysis, testing/validation plans, and stakeholder notifications for significant changes.

Cross-functional leadership

Be the subject matter expert for this effort - the company will look to you for progress reports, external talking points, and guidance.

Mentor engineers on secure design and operational excellence in regulated environments.

Write guidelines, documentation, and create architecture diagrams for external and internal consumption.

Translate between “government compliance language” and “engineering reality.”

What we're looking for

7+ years working in a DevSecOps or related capacity

Experience deploying software into a government-authorized environment (IL6, JWICS)

Full-stack experience - willing to get hand-on across our full stack (React/Node/Python stack)

Strong foundation in security principles and experience developing software against security controls (ex. NIST SP 800-53) and related frameworks (ex. OSCAL)

Strong documentation skills for software accreditation (ex. deployment runbooks, System Security Plans, CONOPS)

Experience working with AWS

Experience working in a fast-paced environment

Exceptional communication skills

Must hold an active U.S. TS Security clearance with SCI Eligibility

What we value (optional)

Experience working for a contractor of the DoW or government agencies

Preference for candidates who are located in, or willing to relocate to San Diego, California. If not open to relocation, frequent travel to San Diego would be required.

What we offer

Competitive Salary

The salary range for this position is $150,000 - $215,000 + equity. Within the range, individual pay is determined by experience, relevant education, and/or training.

Comprehensive Benefits

We’re proud to offer competitive benefits that support our employees. Some key highlights of our benefits package include:

Health, dental, and vision insurance
