Your Mission As a Senior Full Stack Engineer, you are a core partner in the product team, shaping not just how we build, but what we build. Your mission is to architect high-scale systems within a dynamic environment where engineering excellence meets rapid innovation.

You will join a culture of radical end-to-end ownership, where teams deploy to production dozens of times a day. Leveraging a diverse, modern tech stack and cutting-edge tools, you will turn complex architectural challenges into seamless user experiences, knowing that the code you ship in the morning can impact thousands of brands by the afternoon.

Key Responsibilities:
System Architecture: Architect robust, scalable full-stack solutions. You arent just writing code; you are making critical decisions on data modeling, API design, and system resilience.
End-to-End Ownership: Own your features from the whiteboard to production. You build it, you ship it, you run it-giving you complete control over your craft.
Strategic Influence: Partner directly with Product Managers and Designers during Discovery. Your technical insights will validate feasibility and shape the product roadmap before a single line of code is written.
Mentorship & Quality: Be a force multiplier. By conducting code reviews and mentoring junior engineers, you will raise the collective technical bar of the entire team.

As a Staff Engineer, you will be the technical lead and driving force behind the groups most complex initiatives. You will work closely with engineers, tech leads, architects, and product managers to solve high-scale distributed systems challenges, improve performance, and design robust, future-proof systems.

Lead the design and implementation of distributed, high-throughput, low-latency services that support billions of message executions monthly.
Partner with Engineering Managers and Architects to shape the groups long-term technical vision and architecture roadmap.
Define and enforce engineering standards and best practices across services.
Conduct in-depth design and code reviews, mentoring other engineers and elevating technical excellence.
Proactively identify cross-cutting concerns and drive group-wide engineering initiatives (e.g., observability, resiliency, fault tolerance).
Analyze and improve system bottlenecks in data flow, message queuing, storage, and processing pipelines.
Take ownership of non-functional requirements such as reliability, scalability, maintainability, and security.
Collaborate with Product and Data Science teams to ensure engineering plans align with business priorities.
