Reddit jobs

Staff Research Engineer position at Reddit's AI Engineering team focused on post-training and model evaluation for Reddit-native LLMs. Requires ownership of evaluation methodology, model quality benchmarking across Safety/Reasoning/Knowledge, judge design, and post-training recipe development. Role sits at intersection of applied research and infrastructure, supporting Reddit's foundational model development rather than core product software engineering.

This is a backend Software Engineer position in Reddit's Ads organization, focused on microservices, distributed systems, and real-time data pipelines at scale. While the technical fit and seniority align well with James's background and target, the role is restricted to Ontario, Canada, which violates his absolute requirement for US-remote work.

Reddit is hiring a backend engineer for its GraphQL team, which builds the first-party API layer that powers user experiences across the platform. You'll design and maintain foundational GraphQL infrastructure at massive scale, working on challenges like federated architecture adoption, global deployment, developer tooling, observability, and performance tuning across distributed systems. The role requires 5+ years building large-scale distributed backend systems, proficiency in Go or similar languages, cloud infrastructure experience (Kubernetes, CI/CD, AWS/GCP), and strong cross-functional collaboration skills; GraphQL backend experience is a plus. This is a fully remote-friendly position with Reddit's standard benefits package including healthcare, 401(k) match, equity grants, and parental leave, with a base salary range of $190,800–$267,100 USD depending on level and experience. The standout detail is this is a platform infrastructure role at one of the internet's largest platforms (126M daily active users), offering the chance to influence architecture decisions for hundreds of millions of users while mentoring other engineers.
