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 and KMIP, integrations for syncing secrets across cloud providers, and entire new product lines such as Infisical PKI and Infisical SSH.

Responsibilities

• Develop and maintain features whilst communicating directly with enterprise customers.
• Expand our newer Infisical PKI, Infisical SSH, and Infisical KMS 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 United States.

Bonus

• 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.

How You’ll Grow

In this role, you’ll play a pivotal part in shaping Infisical’s future—making key technical decisions, establishing foundational processes, and tackling complex scalability challenges. As you gain experience and the team expands, you'll have the opportunity to take full ownership of specific areas of our platform, driving them end-to-end with autonomy and impact. Overall, you’ll be one of the defining pieces of our team as we scale to thousands of customers over the next 18 months.

Team, Values & Benefits

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.
