The Role

You will join Frontiers, a team of experienced individual contributors building internal software tools for the firm's investing and operations teams. As a software engineer optimizing developer experience, you will own, improve and help with the adoption of our internal developer platform as well as the team's wider product portfolio.

The Frontiers team operates in the mode of an internal startup. We own a tight feedback loop with our users and take on requests from all corners of the firm. In this role, your users are your fellow colleagues — you'll understand their pain points, eliminate friction from their daily workflows, and build the platform and tools that lets everyone build more, faster, and with confidence. While doing so, you will closely work together with your fellow engineers and other teams throughout the firm.

This role requires an in-office presence 2-3 days a week in our San Francisco, CA office.

To join our team, you should be excited to:

Contribute to and help improve the our developer platform, associated with a diverse set of applications

Continuously work with your fellow colleagues to understand, review and assist their diverse use-cases for projects

Build and maintain shared tooling, templates, and internal libraries that accelerate development across the firm’s products

Support observability, monitoring, and alerting so engineers can self-serve when things break in production

Collaborate with the Cybersecurity team to help ensure developer workflows meet security and compliance requirements

Write and maintain developer documentation, onboarding guides, and runbooks that actually get used

Ship improvements iteratively, incorporating feedback from your users to continuously improve the developer experience

Take ownership of assigned projects and services, from development through production support, with increasing autonomy over time

Write clear, well-structured, and maintainable code

Bring positive energy in every interaction with the team and foster inclusive collaboration

Stay curious about new tools, technologies, and approaches relevant to infrastructure and developer productivity

Learn the inner workings of VC and work closely with the investing partnership

Minimum Qualifications

3+ years of professional software engineering experience

Proficiency in Python 3, Rust or similar backend languages and willingness to learn new technologies

Track record of defining and shipping developer platforms or internal tooling that measurably improved engineering velocity

Excitement to work directly with a diverse user group with varying technical backgrounds

Experience deploying services on at least one major cloud platform (GCP, AWS, or Azure)

Experience with containerized services (Docker); experience with Kubernetes is a plus

Exposure to CI/CD systems (GitHub Actions, Cloud Build, CircleCI, or similar)

Experience working with production SQL databases (e.g., PostgreSQL, MySQL); NoSQL experience (e.g., Elasticsearch) is a plus

Experience with infrastructure-as-code concepts (Terraform, Pulumi, or similar) is a plus

Experience working in environments that value rapid iteration, code quality, and operational excellence

Strong problem-solving skills and solid technical fundamentals with a get-it-done mentality

Low ego, high empathy, and the capacity to collaborate effectively with diverse teams

This role is open at the Software Engineer (Partner 16) and Senior Software Engineer (Partner 18) levels. The anticipated salary range for this role is between:

Software Engineer (Partner 16): $269,000 - $314,000
