Staff Software Engineer, Product Data Platform

What you'll do

This opportunity is on our Product Data Platform (PDP) team, which builds and operates the high-performance data, query, and search infrastructure that powers critical Brex product experiences, including AI-powered data products like our agentic reporting experience. PDP's mission is to make Brex customizable, scalable, and reliable for finance teams, and that requires deeply optimized, production-grade distributed systems.

As a Staff Software Engineer, you'll shape the technical direction of the platform across multiple teams. Your mandate is to identify the highest-impact architectural problems across the data products group, including the cross-cutting ones that fall between teams, and drive them to resolution. You'll be accountable for the group's technical quality, move between long-horizon strategy and hands-on execution, and lead through influence rather than authority.

Where you'll work

This role will be based in our Seattle office. We are a hybrid environment requiring a minimum of three coordinated days in the office per week (Monday, Wednesday, and Thursday), with up to four weeks per year of fully remote work.

Responsibilities

• Lead technical strategy for critical PDP initiatives, balancing long-term architecture with near-term delivery across multiple teams.
• Identify and resolve systemic performance, consistency, and scalability problems, including cross-team gaps no single team can own.
• Own architecture direction for query performance: query plans, execution paths, cost models, indexing strategies, and schema and access-pattern design.
• Design and evolve distributed systems with thoughtful tradeoffs around consistency, latency, caching, cost, and failure modes.
• Raise the technical bar across the group through design reviews and architecture decisions, and dive in hands-on where it matters most, including P95/P99 latency issues in production.
• Proactively identify scaling risks and reliability gaps, and turn findings into plans the group aligns behind.
• Mentor senior engineers and grow the next generation of technical leaders within PDP.
• Contribute directly on high-stakes initiatives and critical path decisions, primarily in the JVM ecosystem (Kotlin/Java).

Requirements

• 8+ years of backend engineering experience building and operating production systems at scale, including as a technical leader on multi-team initiatives.
• Track record of leading architecture and delivery for large-scale distributed systems in a platform or infrastructure environment.
• Deep hands-on expertise with relational databases (Postgres or Aurora strongly preferred), including query plan analysis, indexing strategies, and real-world optimization.
• Ability to drive ambiguous, cross-cutting problems to resolution without a defined charter.
• Strong written and verbal communication, with the ability to influence stakeholders and align teams without direct authority.
• Experience mentoring senior engineers.

Bonus

• Hands-on experience with OpenSearch / Elasticsearch or similar systems in production.
• Experience with streaming data platforms (Flink, Kafka) or semantic/analytics layers in production.
• Experience with multi-tenant or data-heavy platforms in regulated environments.
• Experience building platform foundations for AI or agentic product experiences.
