Key Skills

React.js Node.js TypeScript Go Open Source Security DevOps Startup Experience Enterprise Software Full Stack Development

Dear Hiring Team,

I am excited to apply for the Senior Full Stack Engineer position at Infisical. With over 5 years of experience building scalable web applications using React, Node.js, and TypeScript, I am drawn to your mission of simplifying security infrastructure for developers. I have a strong track record of taking ownership of complex features, from design to deployment, and have worked directly with enterprise customers to deliver tailored solutions.

Your emphasis on autonomy and fast iteration resonates with my approach—I thrive in environments where I can make decisions with incomplete information and adapt quickly. I am particularly interested in contributing to your PKI and SSH product lines, as I have experience with security protocols and developer tools. Additionally, my background in open source projects has taught me the value of community-driven development and clear communication.

I am eager to bring my technical expertise and passion for security to Infisical, and I look forward to the possibility of discussing how I can contribute to your team. Thank you for your consideration.

Describe a time when you had to make a technical decision with incomplete information. How did you handle it?
In my previous role, we needed to choose a database for a new feature, but we had limited data on traffic patterns. I researched options, built a small prototype with PostgreSQL, and implemented basic metrics to validate performance over time. This allowed us to make a decision quickly and iterate based on real usage.
How would you approach designing a feature to rotate secrets automatically?
I would start by understanding the security requirements and the impact on existing systems. Then I'd design a secure, idempotent rotation process that minimizes downtime, using infrastructure-as-code and event-driven triggers. I'd also ensure audit logging and rollback capabilities.
Explain how you would optimize a React application for performance.
I would analyze the component tree with React DevTools, identify unnecessary re-renders, and use techniques like memoization, virtualization for long lists, and code splitting. I'd also ensure that state management is efficient and that API calls are minimized or batched.
How do you handle communication with customers when they have a feature request that conflicts with the product roadmap?
I would listen carefully to understand their core needs, then explain the current roadmap and trade-offs. I'd collaborate with the product team to see if there's a simpler workaround or a way to adjust timelines. The goal is to make the customer feel heard while aligning with strategic priorities.
What experience do you have with open source contributions, and how do you maintain code quality in a collaborative environment?
I have contributed to several open source projects by fixing bugs and adding features. To maintain quality, I follow code reviews, enforce testing standards, and document decisions. I'm comfortable giving and receiving constructive feedback to ensure the codebase remains robust.

Infisical is looking to hire exceptional talent to join our teams in building the open source security infrastructure stack for the AI era.

We’re building a generational company with a world-class team. This isn’t a place to coast — but if you want to grow fast, take ownership, and solve tough problems, you’ll be challenged like nowhere else.

What We’re Looking For

 

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

 

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, 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 North or South America.

 

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

Our team brings experience from companies like Figma, AWS, and Red Hat. 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.

 

About Us

Infisical is the open source security infrastructure platform that engineers use for secrets, certificates, and privileged access management. We help developers and organizations securely manage over 1.5 billion secrets each 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, Lucid, and LG.

 

Join us on a mission to make security easier for all developers — starting with secrets management.
