Sample interview questions
How would you design a secure secrets-rotation workflow for applications with minimal downtime?

I would first identify the credential type, dependent services, rotation constraints, and rollback requirements. I would use overlapping credential validity where supported, automate issuance and distribution through a secure control plane, and update consumers through short-lived credentials or atomic configuration changes. I would also add audit logs, health checks, alerting, and a tested rollback path before enabling automatic rotation.

Describe how you would structure a React and Node.js feature that lets enterprise users manage access policies.

I would model policies explicitly with versioned schemas and enforce authorization on the server rather than trusting the client. The React interface would provide clear validation, previews of policy effects, and safe defaults, while the Node.js API would validate inputs, perform authorization checks, persist changes transactionally, and emit audit events. I would accompany the feature with unit, integration, and permission-boundary tests.

How do you make effective technical decisions when requirements are incomplete?

I clarify the user outcome, security constraints, and reversible versus irreversible decisions, then document assumptions and propose a small, measurable first iteration. I seek input from relevant engineers and customers when the decision affects them, but avoid blocking on perfect information. After release, I use telemetry and feedback to validate the decision and adjust quickly.

What security considerations are important when building integrations that sync secrets with cloud providers?

The integration should follow least privilege, use narrowly scoped and preferably short-lived cloud credentials, encrypt secrets in transit and at rest, and avoid exposing plaintext in logs or error messages. I would validate provider identity and permissions, implement idempotent sync behavior, maintain comprehensive audit trails, and design secure handling for retries, revocation, and credential rotation.

How would you handle direct feedback from an enterprise customer requesting an urgent platform feature?

I would first understand the customer's underlying problem, urgency, security impact, and success criteria. I would assess whether an existing capability, configuration, or smaller workaround addresses the need, then communicate a realistic plan and tradeoffs with the customer and internal stakeholders. If the feature is prioritized, I would deliver it in safe increments, keep the customer informed, and use their feedback to refine the solution.

Opportunity details

About this role.

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 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 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, Infisical PAM, 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.

  • 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.
