RWJF

Full-stack Engineer

• Improve developer velocity across the engineering organization. You'll measure and optimize the inner loop - how long it takes an engineer to go from code change to confident production deployment. This includes build times, test parallelization, deployment rollout speed, and the tooling engineers interact with every day.
• Shape the architecture of Ladder's production infrastructure. You'll evaluate trade-offs and make high-impact technical decisions — like whether to replace custom monitoring tooling with native cloud provider integrations, or redesign how we rebuild data pipelines when upstream logic changes. You'll be the person who sees the big picture across systems and decides where to invest engineering effort.
• Participate in incident response for infrastructure, run retrospectives, and help drive follow-through on fixes as part of the team.
• Systematically pay down infrastructure tech debt. You'll partner with your team to identify legacy systems that have been superseded by better alternatives and build a roadmap to retire them — migrating from bespoke systems to native integrations, cleaning up remnants of past cloud migrations, and upgrading components that have drifted behind.
• You'll raise the engineering bar through code reviews, design reviews, and technical guidance - not through formal management, but through the quality and clarity of your technical work.

Senior Software Engineer, Infrastructure

Data Engineer

• Architect and Build: Design, deploy, and scale robust data pipelines that reliably move and transform data between Datomic, Kafka, and BigQuery.
• Tame the Chaos: Build elegant, fault-tolerant ETL systems leveraging frameworks like DBT to ingest, sanitize, and normalize messy, unstructured data from dozens of third-party APIs and legacy vendors.
• Master the Stream: Evolve our event-driven architecture, optimizing streaming performance (Kafka/BEAM) to support real-time machine learning models.
• Drive Technical Excellence: Act as a force multiplier for the engineering team. You'll set standards for backend architecture in Clojure, mentor peers, and make high-stakes technical decisions that scale with our rapid growth.
• Bridge the Gap: Partner closely with Data Science, Product and Business Development teams to ensure our data infrastructure proactively serves the evolving needs of the business.
