Senior Software Engineer

About the role

I’m hiring a Software Engineering Lead to help me (the CTO) improve how federal tech gets delivered. This is a hands-on leadership role: you’ll own critical systems end-to-end, set a high technical bar, and grow a team that ships with speed and rigor. We operate where it’s hardest — security, reliability, scale, and clarity under ambiguity. This role is ideal for a senior level individual contributor with demonstrated experience conducting code-reviews, mentoring junior developers and liaising across other business units.

Responsibilities

• Lead the design and development of complex, full-stack software systems, contributing hands-on across the stack.
• Review code, maintain high engineering standards, and mentor engineers through technical guidance and feedback.
• Scope and design scalable system architectures, ensuring reliability, performance, and maintainability.
• Collaborate cross-functionally with teams such as Sales, Mission Ops, and Marketing to align product delivery with customer and business needs.
• Drive development workflows and release coordination, ensuring smooth deployments and high-quality production systems.
• Contribute to building modern AI-enabled products, including backend services, workflows, and integrations with LLM-powered systems.
• Help grow the engineering team by participating in hiring and technical interviews.

Requirements

• 5+ years of professional software engineering experience with demonstrated technical leadership on complex systems or products.
• A hands-on engineer who still enjoys coding while taking on leadership responsibilities.
• Background as a Tech Lead, Senior/Staff Engineer, early engineer at a high-growth startup, or founder/co-founder of a startup.
• Experience building modern web applications with frameworks such as React or Next.js, with strong product intuition and UX/design sensibility.
• Backend expertise with modern frameworks such as Django, FastAPI, or Node.js, along with strong SQL and system design fundamentals.
• Experience building or integrating AI/LLM-powered systems or workflows.
• Familiarity with modern infrastructure and tooling such as AWS, GCP, or Azure, along with workflow or systems tooling (e.g., Temporal, Airflow, Prefect, Redis, OAuth).
• Strong communicator who is comfortable collaborating with cross-functional teams and occasionally engaging with customers.
• Motivated, intellectually curious, and driven to build exceptional products with a high-performing team.
• Located in or willing to relocate to Boston, MA.
• US Person.

Qualifications

• Led teams building or personally built complex, distributed systems with real users and uptime requirements.
• Demonstrated mastery in at least one of our core areas:
  • Backend/Data: APIs, ETL
  • Frontend: UI/UX
  • Search/Analytics: PostgreSQL, Elasticsearch, schema design, relevance tuning
• Designed resilient architectures: clear boundaries, smooth releases, and instrumentation that catches issues before users do.
• Communicated clearly with both technical and non-technical stakeholders. You can argue from first principles and then ship the pragmatic thing.
• Bonus experience with distributed systems, ETL/data pipelines, DevOps tooling (Kubernetes, Helm), or mobile development.
• Veterans strongly encouraged to apply.

Benefits

• Equity opportunity.
• Platinum Healthcare: comprehensive medical, dental, and vision coverage for you and your dependents, fully covered by Pryzm.
• Basic Life/AD&D and long-term disability insurance fully covered, with the option to purchase additional life insurance for you and your dependents.
