Engineering Manager, Developer Infrastructure

The Mission

The backend infrastructure team enables fast, reliable product development at Fullscript by defining and upholding engineering standards for quality, scalability, and maintainability.

We own the long-term technical health of Fullscript’s core Ruby on Rails application and the experience developers have working within it. Through foundational upgrades, shared tooling, and cross-team infrastructure projects, we help product teams move quickly and build confidently as the company grows.

The Role

We’re looking for a hands-on Engineering Manager to lead our backend infrastructure team.

This role combines people leadership, technical direction, and project execution. You’ll grow a strong team, set a clear roadmap, and guide decisions that improve application health and developer productivity.

You’ll stay close to the technical work through solution design, code review, and hands-on contributions where they’re most useful. You’ll also partner with engineering leaders and product teams to prioritize platform investments, coordinate changes, and connect technical improvements to business needs.

What You'll Do

• Lead, coach, and develop engineers through clear expectations, regular feedback, career development, and performance management.

• Build a team culture grounded in ownership, collaboration, learning, and technical excellence.

• Own the team’s roadmap, balancing immediate developer needs, foundational improvements, and long-term application health.

• Guide technical direction for our Rails monolith, improving code structure, maintainability, scalability, reliability, and security.

• Lead foundational upgrades across Ruby, Rails, and related frameworks and dependencies, coordinating migration and release plans with affected teams.

• Improve developer productivity through shared tooling, CI checks, testing infrastructure, documentation, and simpler development workflows.

• Oversee shared application infrastructure, including feature flags, end-to-end tests, and infrastructure-as-code within the monolith.

• Coordinate cross-team projects, making scope, ownership, dependencies, risks, and progress clear.

• Partner with product engineering teams to resolve recurring technical problems and support adoption of shared tools and standards.

• Define and track meaningful outcomes, such as faster feedback cycles, fewer recurring failures, and less time spent working around platform limitations.

How We Expect You To Think

• Developers are your users. Understand their day-to-day problems and involve them in shaping solutions.

• Platform work should produce clear outcomes. Connect investments to developer productivity, application reliability, and product delivery.

• Standards work best when they’re practical, well explained, and supported by tooling that makes them easy to follow.

• Modernization should be incremental and purposeful. Improve existing systems with a clear understanding of the benefits, costs, and migration risks.

• Adoption is part of delivery. Documentation, communication, and support matter alongside implementation.

• Strong people leadership creates technical ownership. Give engineers context, clear expectations, and room to make decisions.

• Balance today’s commitments with tomorrow’s maintenance costs. Make tradeoffs explicit and revisit them as needs change.

What You Bring

• Experience managing software engineers, including coaching, career development, performance management, and hiring.

• Must have a strong backend engineering background with Ruby on Rails and experience maintaining production applications.

• Sound technical judgment across application architecture, testing, performance, reliability, and security.

• Experience leading platform, infrastructure, developer experience, or other technical work that serves multiple teams.

• Strong project and program management skills, including coordinating dependencies, managing delivery risks, and guiding changes through rollout.

• The ability to turn broad technical needs into a prioritized roadmap and communicate why the work matters.

• Strong collaboration skills and the ability to build agreement across teams with different priorities.

• Comfort moving between people management, technical guidance, and delivery, while helping engineers take ownership.

Bonus

• Experience evolving a large Rails monolith or supporting high-scale web applications.

• Experience leading major framework upgrades or migrations across multiple teams.

• Experience improving CI pipelines, test suites, feature flag systems, or developer tooling.

• Familiarity with infrastructure-as-code, React, Remix, or GraphQL.

• Experience in e-commerce or health tech.

• Experience thoughtfully applying AI-assisted tools to engineering workflows, with attention to code quality, security, and maintainability.
