## Job description

Infisical is the open source security infrastructure platform that engineers use for secrets management, certificates, and privileged access management. We help developers and organizations securely manage billions of secrets every month including application configuration, database credentials, certificates, and more.

We’ve raised $19M from Y Combinator, Google, and Elad Gil, and our customers include Hugging Face, OpenRouter, LG, and NVIDIA.

Join us on a mission to make security easier for all developers — starting with secrets management. We’re looking to hire exceptional talent to join us in building the open source security infrastructure stack for the AI era.

## About the role

We’re looking for an exceptional Senior Full Stack Engineer to help us build, optimize, and expand the foundation of the platform.

We’ve kept our hiring standards exceptionally high since we expect engineers to tackle a broad range of challenges on a day-to-day basis. Examples of past engineering initiatives include developing strategies for secret rotation and dynamic secrets, a gateway to provide secure access to private resources, protocols like EST https://infisical.com/docs/documentation/platform/pki/est and KMIP https://infisical.com/docs/documentation/platform/kms/kmip#kmip-integration, integrations for syncing secrets across cloud providers, and entire new product lines such as Infisical PKI and Infisical PAM.

You’ll be working closely with our CTO and the rest of the engineering team to:

- Develop and maintain features whilst communicating directly with enterprise customers.
- Expand our newer Infisical PKI https://infisical.com/docs/documentation/platform/pki/overview, Infisical PAM https://infisical.com/docs/documentation/platform/pam/overview, and Infisical KMS https://infisical.com/docs/documentation/platform/kms/overview product lines.
- Experiment with novel approaches for applying AI to secrets management and more broadly security infrastructure.

## Requirements

- Deep technical mastery of the JavaScript ecosystem, particularly React.js, Node.js, and TypeScript (3+).
- Exceptional attention to detail and eager to learn.
- A bias toward action—able to make decisions with incomplete information, iterate quickly, and take calculated risks.
- Based in the Americas (US or Canada), Brazil, India, UK, or EU. Must work US hours.

## Nice to have

- Expertise in Go.
- Has some understanding of devops/developer tools.
- Previous founder or startup experience.
- Previous experience building in open source or developer tools in either a professional or personal setting.
- Excellent written and oral communication skills to interact with customers directly.

## Team, values & benefits

Our team brings experience from companies like Databricks, AWS, Red Hat, and more. We operate primarily as a remote team, but maintain a strong presence in San Francisco, where we have an office. We also get together in person throughout the year for off-sites, conferences, and team gatherings.

At Infisical, we offer competitive compensation, including both salary and equity options. Additional benefits, such as a lunch stipend and a work setup budget, are available with more details to be found on our careers page https://infisical.com/careers.
