Senior Engineer

Developer Experience (DX) Team

New York City, NY

Boston, MA

Broomfield, CO

Hybrid Schedule (M/F remote, T/W/TH in-office)

East Coast - Remote

In this role you will:  

Join the Developer Experience (DX) team as a Senior Engineer. This leverage role is for an engineer passionate about multiplying the effectiveness of others through improved tooling, automation, libraries, and workflows.

You will design and build shared engineering capabilities used across Magnite, with a strong focus on AI-enabled development, platform tooling, and developer productivity. Comfort working with Java, Python and Typescript. Rust knowledge is a strong plus. You must bring hands-on experience with modern AI providers and engineering tools such as Cursor, Claude, Codex, and related ecosystems.

You will partner with engineering teams and leadership to identify high-friction workflows, build scalable solutions, and drive adoption through clear documentation and enablement. This is not a feature-delivery role for a single product team; it is a leverage role focused on improving how engineering gets done across the organization.

Developer Platform & Tooling

• Design, build, and maintain shared developer tooling and platform capabilities that improve engineering productivity across teams.

• Collaborate with SRE and engineering teams to design and 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.

AI-Enabled Engineering

• 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.

Shared Engineering Capabilities

• 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.

• Design solutions that are maintainable, observable, secure, and easy for partner teams to adopt.

Standards, Enablement, and Adoption

• Partner with engineering teams to understand friction points and translate them into scalable solutions.

• Produce high-quality documentation, examples, migration guides, and adoption playbooks that enable self-service.

• Support adoption through design collaboration, pairing, and time-boxed engagements where needed.

• Promote standards through useful paved roads and working solutions, minimizing process overhead or gatekeeping.

Quality, Reliability, and Measurement

• Ensure DX-owned tooling and shared components are reliable, secure, observable, and well supported.

• Use data to measure impact, including build/test performance, adoption, reliability, and engineering satisfaction.

• Continuously improve solutions based on developer feedback, operational signals, and usage patterns.

We’re looking for someone with: 

• 4+ years of professional software engineering experience and 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). Must demonstrate experience translating AI capabilities into concrete engineering outcomes, such as developer workflows, assistants, automation, or knowledge-enabled tooling.

• Strong software design and systems thinking, with the ability to balance 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.

In NY, MA, and the East Coast, the base salary range for this role is $155,000 – $165,000.

In CO, the base salary range for this role is $140,000 - $150,000.
