What We’re Looking For

As a Staff Software Engineer , you’ll be at the heart of designing and building the scalable infrastructure that powers everything behind Puzzle. This is a hands-on, high-impact role where you'll help shape the architecture, drive scalability, and ensure the reliability of the core systems that support our product.

What You’ll Do

Design and implement core infrastructure to support high-availability, low-latency systems and services at scale.

Design, build, and productize critical components of our financial system- laying the groundwork for a system that’s as powerful as it is intuitive.

Continuously identify opportunities to improve performance, resilience, and developer velocity across our platform.

Partner with product, design, and data teams to translate business needs into well-defined technical implementations.

Work cross functionally to troubleshoot complex systems and be a technical voice in navigating trade-offs and prioritization.

Craft technical solutions to high-impact business challenges while staying deeply attuned to the broader context behind complex company decisions.

Guide and mentor other engineers through code reviews, pairing, and technical leadership- assisting with engineer onboarding and training as needed.

Who You Are

BS or MS in Computer Science, Engineering, or equivalent experience.

7+ years of software engineering experience with a proven track record of architecting and delivering complex backend systems- taking projects from initial concept all the way through to production.

Deep understanding of system architecture and the interconnected layers that make complex systems work seamlessly together.

Past experience in system design and scaling large data applications is essential.

Solid experience in database design and analytics, with proficiency in both SQL and NoSQL preferred.

Experience optimizing system and application performance, with a strong track record in debugging and troubleshooting large-scale software.

Excellent communication and collaboration skills, with a strong team ethic and the ability to work seamlessly with both technical and non-technical stakeholders.

Demonstrated ability to deliver work with precision, attention to detail, and a high degree of accuracy.

Comfortable operating in a high-ownership, fast-paced startup environment.

Passion for mentoring and growing engineering talent.
