About Infisical
Infisical is the open source security infrastructure platform engineers use for secrets management, internal PKI, key management, and SSH workflow orchestration. They help developers and organizations securely manage over 1.5 billion secrets each month — including application configuration, database credentials, and certificates. Backed by $19M in funding from Y Combinator, Google, and Elad Gil, with customers including Hugging Face, Lucid, and LG.
About the Role
Infisical is hiring exceptional engineers to help build the open source security infrastructure stack for the AI era. This is a high-ownership, fast-growth environment — engineers tackle a broad range of challenges, from secret rotation and dynamic secrets strategy, to building secure access gateways, implementing protocols like EST and KMIP, syncing secrets across cloud providers, and launching entirely new product lines (Infisical PKI, Infisical SSH).
As a Full Stack Engineer, you'll work closely with the CTO and engineering team to:
- Develop and maintain features while communicating directly with enterprise customers
- Expand the newer Infisical PKI, Infisical SSH, and Infisical KMS product lines
- Experiment with novel approaches for applying AI to secrets management and broader security infrastructure
Required Skills
- Node.js, TypeScript
- Deep technical mastery of the JavaScript ecosystem, particularly React.js, Node.js, and TypeScript
- Exceptional attention to detail and eagerness to learn
- A bias toward action — comfortable making decisions with incomplete information, iterating quickly, and taking calculated risks
- Based in the Americas (US, Canada, or LATAM) — note: candidates based in or willing to relocate to San Francisco should see the SF-specific listing for on-site work
Bonus Qualifications
- Expertise in Go
- Understanding of DevOps/developer tools
- Previous founder or startup experience
- Experience building in open source or developer tools (professional or personal)
- Excellent written and oral communication skills for direct customer interaction
Growth Opportunity
This role plays a pivotal part in shaping Infisical's future — making key technical decisions, establishing foundational processes, and solving complex scalability challenges. As the team grows, you'll have the opportunity to take full ownership of specific platform areas, driving them end-to-end with autonomy and impact. You'll be a defining member of the team as Infisical scales to thousands of customers over the next 18 months.
Team & Culture
The team brings experience from companies like Figma, AWS, and Red Hat. Infisical operates primarily remote with a strong presence in San Francisco (where they maintain an office), plus periodic in-person off-sites, conferences, and team gatherings.
Compensation & Benefits
Competitive salary and equity options, plus additional benefits such as a lunch stipend and work setup budget (full details on their careers page).
