We’re the Developer Experience (DX) team  mission is to make engineers faster, safer, and happier shipping production software by improving the tools, platforms, workflows, and shared engineering capabilities used across the company. We reduce friction in the inner loop of development—build, test, run, debug, including CI/CD, releases, observability, reliability, and engineering standards. We build shared platforms, reusable tooling, paved paths, and reference implementations that help teams move faster with less bespoke plumbing and higher confidence.

• Design, build, and maintain shared engineering capabilities used across Magnite, with a strong focus on AI-enabled development, platform tooling, and developer productivity.
• Collaborate with SRE and engineering teams to deliver reusable solutions for common development needs, including service scaffolding, local development workflows, CI/CD patterns, automation, and release tooling.
• Improve the developer experience across the software lifecycle, from code authoring and testing through deployment and supportability.
• Evaluate, integrate, and operationalize AI tools and workflows—using various providers, APIs, SDKs, third‑party solutions, and agent‑style tools—to improve engineering output, quality, knowledge access, and delivery speed.
• Identify and build high‑value use cases for AI in software development, such as code generation, code review assistance, documentation, migration support, and internal developer assistants.
• Help define safe, effective patterns for adopting AI in day‑to‑day engineering work.
• Build and evolve shared libraries, utilities, reference implementations, and templates (e.g., for configuration, logging, telemetry, resilience, and engineering standards) to reduce duplicated effort across teams.
• Partner with engineering teams to understand friction points and translate them into scalable solutions, producing high‑quality documentation, examples, migration guides, and adoption playbooks.
• Support adoption through design collaboration, pairing, and time‑boxed engagements as needed.
• Promote standards through paved roads and working solutions, minimizing process overhead or gatekeeping.
• Ensure DX‑owned tooling and shared components are reliable, secure, observable, and well supported, using data to measure impact—build/test performance, adoption, reliability, and engineering satisfaction—and continuously improve based on feedback.

• 4+ years of professional software engineering experience with a strong track record of building production‑grade systems, tooling, or shared platforms.
• Strong proficiency in Java and Python, including writing clean, maintainable, well‑tested code and designing reusable abstractions.
• Hands‑on experience building developer tooling, internal platforms, shared libraries, automation, or productivity‑focused engineering solutions.
• Strong practical experience with modern AI providers, models, and APIs (e.g., Cursor, Claude, Codex) and ability to translate AI capabilities into concrete engineering outcomes.
• Strong software design and systems thinking, balancing flexibility, standardization, usability, and long‑term maintainability.
• Experience with CI/CD systems, build tooling, developer workflows, and release automation.
• Familiarity with observability practices, including logs, metrics, tracing, and operational readiness.
• Strong communication and collaboration skills, with the ability to work across teams and influence through clarity, practicality, and technical credibility.

• Base salary range: $155,000–$165,000 (NY, MA, East Coast); $140,000–$150,000 (CO).
• Annual performance‑based bonus (eligible).
• Equity (NASDAQ: MGNI).
• Comprehensive benefits package: healthcare coverage from Day One, generous time off, holidays, quarterly wellness days, employee stock purchase plan, family‑focused benefits and parental leave, 401(k) with employer match, disability and life insurance, cell phone subsidy, monthly fitness reimbursement, career growth opportunities.
