Staff Engineer, Authentication and Authorization

Are you a visionary and experienced software engineer with a passion for authentication and authorization? Are you excited about things like identity and access management (IAM), permissions, access tokens,
- factor authentication (MFA) and single
- on (SSO)? Do you thrive on tackling complex technical challenges and building scalable systems? If this sounds like you, Pleo needs your expertise!

We are about to create a dedicated auth team that rethinks and renews how authentication and authorization are handled in Pleo with the goal to ensure the security and integrity of our systems. We intend to follow open industry standards and use third party providers. You’ll be working closely with product teams to make auth as easy to use as possible, but also with platform teams like Backend Core that provide common libraries and internal frameworks as well as with the Security team.

Why you should apply:

As a Staff Engineer at Pleo, you won't just solve problems; you'll redefine how we do things. We're searching for an engineering powerhouse with a
- focused mindset who is eager to mentor, innovate, and drive strategic vision.

In this role, you'll be a force multiplier—elevating the team's performance and delivering impactful solutions that ripple across the entire credit offering. You'll act as the glue between where are and where we want to be, steering the technical direction and empowering everyone to excel.

What you'll do:

• Architectural Ownership: Take charge of critical system components.
• Visionary Thinking: Articulate the 'why' behind each technical decision with clarity and passion.
• Continuous Innovation: Bring fresh ideas and strategic
  - offs rooted in a deep understanding of our users.
• Iterative Development: Build features incrementally with a focus on early feedback and continuous improvement.
• Mentorship: Foster a culture of innovation and collaboration through technical coaching and inclusion.

What success looks like:

• Scalable Infrastructure: More performance, fewer bugs.
• Testing Excellence: Catch those pesky bugs before our users do.
• Reliable Delivery: Ensure consistent, timely delivery that meets user and stakeholders needs.
• Innovative Solutions: Identify creative and scalable technology solutions that make Auth
  N and Auth
  Z surprisingly easy for our internal product teams.
• Motivated Team: Contribute towards forming a
  - performing, cohesive team through mentorship and embodying our team culture of curiosity, humility and kindness.

You know your way around:

• Cloud environments / distributed systems / microservices (AWS, Google Cloud, Kubernetes)
• Architecting scalable solutions and API design
• Authentication & authorisation for APIs
• Server-side languages (we mainly use Kotlin and Type
  Script)
• Testing frameworks, observability, and monitoring
• Optional but beneficial: 3rd party authentication providers

Your colleagues would say you are:

• An outstanding communicator who can clearly share ideas
• Perpetually curious, always learning new technologies and methodologies
• A dedicated coach for fellow engineers, helping them grow
• A proponent of thorough code review processes and testing
• A key contributor to designing holistic solutions, not just writing code
• Someone they’d enjoy having a coffee with
• Naturally inclined to solve intricate problems and drive towards effective solutions
