Senior Software Engineer - DevX

Reddit is a community platform built around shared interests, discussions, and user-generated content. The Senior Software Engineer - DevX will design and build scalable backend systems, infrastructure, platforms, APIs, and AI-powered developer workflows that improve how Reddit engineers develop, test, review, deploy, and operate software. The role also involves leading high-impact projects, collaborating across engineering teams, mentoring engineers, and improving developer productivity, reliability, and usability.

Responsibilities:

• Work cross-functionally across Reddit Engineering to understand developer needs, quickly prototype solutions, and iterate based on feedback
• Design and build backend systems, APIs, infrastructure, and platform capabilities that improve developer workflows across Reddit
• Build scalable and reliable systems across both AI-powered developer workflows and the core non-AI systems engineers rely on every day
• Lead high-impact projects across Reddit’s developer tooling ecosystem by writing and reviewing code and design docs, aligning stakeholders, and making pragmatic technical tradeoffs
• Build tools and integrations that connect developer workflows with Reddit’s existing infrastructure, CI/CD, security, source control, deployment, and operational systems
• Design and implement maintainable APIs, services, libraries, and platforms that support internal developer tooling at scale
• Improve the team’s tools, processes, and best practices while raising the bar for reliability, usability, scalability, and maintainability
• Mentor engineers and help shape a roadmap that reflects real developer needs and delivers meaningful improvements to Reddit’s engineering organization

Requirements:

• 5+ years of hands-on, post-grad, non-internship professional software development experience, with backend, infrastructure, or platform engineering as a core strength
• 3+ years of industry experience working on large-scale distributed systems, including building and improving highly scalable and reliable services
• Strong proficiency with Go, and significant experience with Go in production systems
• Experience designing and implementing maintainable APIs using technologies such as GraphQL, REST, HTTP, or gRPC
• Experience building platforms, developer tools, libraries, frameworks, or internal systems used by other engineers
• Experience with infrastructure, Kubernetes, cloud providers, or other systems that support modern software development and delivery
• Hands-on experience using AI-powered developer tools and workflows, with curiosity and judgment about where these tools can meaningfully improve developer productivity
• A track record of leading large, ambiguous, high-impact projects that require cross-team collaboration, technical judgment, stakeholder alignment, and clear ownership from problem definition through delivery
• A user-focused mindset, with strong empathy for internal engineering users and a focus on usability, reliability, scalability, and quality
• Excellent communication skills, with the ability to influence technical direction and navigate complex requirements across technical and non-technical stakeholders
• Experience mentoring engineers, raising the technical bar, and helping teams make pragmatic tradeoffs
• A self-directed, action-oriented approach. You are comfortable operating in ambiguity, learning quickly, and driving work forward even when the path is not fully defined
• Experience working in developer experience, developer productivity, internal platforms, or developer tooling
• Experience building tools or workflows for internal engineering users
• Experience building or extending CI/CD systems, and partnering with teams that own build, test, and release workflows
• Experience with GitHub Enterprise Server or large-scale source control platforms
• Experience with Python
• Experience measuring the impact of platform or developer productivity work through experimentation, measured rollouts, analytics, reliability metrics, or qualitative feedback
