Software Engineer, Resilience
ABOUT THE ROLE
This isn't just another engineering role. This is a unique opportunity to be a founding member of our new Resilience Engineering function and shape the future of performance and scalability at Persona. As our products grow in complexity and adoption, we're building a specialized team to act as a force multiplier for all of engineering. You won't own a single service; instead, you'll be a trusted partner embedded within product teams, tackling their most critical challenges in performance, scalability, and observability. We’re looking for someone who is a systems thinker, part detective, part diplomat, and part architect, and who’s ready to help build a new function from the ground up.
WHAT YOU'LL DO AT PERSONA
- Partner with product teams on short-term, high-impact projects to solve their most pressing performance and observability challenges.
- Dive deep into major incidents to uncover underlying architectural causes and drive systemic improvements to prevent future failures.
- Design, build, and promote reusable resilience patterns and tooling that make it easy for all engineers to build reliable services.
- Own and advance our observability strategy, defining the standards and building the tools that help us understand system health.
- Mentor and coach engineers across the organization, raising the technical bar for performance and reliability.
- Establish and drive a new Operational Excellence review process to foster a culture of accountability and continuous learning.
- Help define and measure SLOs for our most critical user journeys, making our product tangibly faster and more reliable for customers.
WHAT YOU'LL BRING TO PERSONA
- A strong software engineering background, demonstrated by 7+ years of experience building and shipping complex production systems.
- Direct experience in performance, scalability, or observability is a significant plus, but not required for a candidate with a deep engineering foundation.
- Enjoys mentoring other engineers and can clearly and concisely explain complex technical ideas.
- Deep expertise in the three pillars of observability (metrics, logs, and traces) and experience in instrumenting complex, distributed systems.
- The ability to listen with empathy, build trust, and influence other teams without direct authority.
- Ability to build robust, well-tested libraries and tools that improve the work of other engineers.
- Takes Initiative, comfortable with ambiguity, and effective at driving projects in a new and evolving environment.
