Principal Site Reliability Engineer-Hybrid Boston, MA

We are looking for a Principal Site Reliability Engineer (SRE) to play a critical role in ensuring the longterm reliability, scalability, and operational excellence of our platform.

As a Principal SRE, you will operate with a high degree of autonomy and influence. You will lead complex, crossorganization reliability initiatives, shape reliability strategy, and serve as a technical authority and trusted advisor across engineering.

Your work will directly shape the experience of our customers by ensuring the platform is fast, resilient, and dependable. As a Principal SRE, you will help protect customer trust by driving reliability across the entire system lifecycle.

This role is ideal for engineers who enjoy solving ambiguous, highimpact problems at scale, influencing system design across teams, and raising the reliability bar for an entire organization.

• Lead design, implementation, and evolution of reliability, availability, and resiliency strategies for largescale distributed systems written primarily in Java
• Apply deep experience operating complex, distributed systems to guide architectural decisions, reliability strategies, and longterm system evolution
• Identify systemic risks in application architecture, data flows, and infrastructure, and drive architectural improvements that measurably improve availability, performance, and scalability
• Set and evolve reliability standards, best practices, and operational principles across R&D

• Lead efforts to prevent, detect, and mitigate incidents through technical improvements and operational maturity
• Serve as a senior coordination point during major incidents, helping manage response and guide longterm remediation
• Champion blameless post-incident reviews and ensure learnings translate into durable system improvements

• Apply advanced software engineering practices to eliminate manual work, reduce operational load, and improve system observability
• Design and build internal platforms, automation, and tooling that support Javabased services and their operational needs
• Raise the bar on monitoring, alerting, and SLO/SLI adoption across systems

• Partner deeply with product engineers, architects, and engineering leadership to ensure reliability and operability are firstclass concerns in system design
• Review and influence designs for complex systems involving technologies such as datastores, messaging systems, and coordination services
• Serve as a technical mentor and coach for SREs and other engineers, raising overall engineering and operational maturity

• Contribute to longerterm reliability and infrastructure strategy aligned with business growth
• Stay current with industry trends in SRE, distributed systems, and the Java ecosystem, turning insights into practical improvements
• Help define what "great reliability" looks like for the organization and how we measure it

• Ability to commute to the Seaport Boston office 2-3 days a week.
• 7+ years of experience in software engineering, site reliability engineering, or systems engineering roles
• Extremely strong proficiency with the Java programming language and its ecosystem, including building, debugging, and operating production Java services
• Deep experience operating complex, distributed systems in production environments
• Strong software engineering background, with a track record of delivering highquality, maintainable code

• Expert understanding of incident management, service reliability, and performance engineering
• Strong handson experience with observability (metrics, logs, traces), capacity planning, and SLOdriven reliability
• Deep familiarity with modern cloudbased infrastructure, CI/CD pipelines, and infrastructureascode practices
• Ability to reason about failure modes across application, data, and infrastructure layers

• Demonstrated ability to lead complex initiatives that span teams and organizational boundaries
• Comfortable making highimpact technical decisions in ambiguous environments
• Strong communicator who can influence design and operational decisions across a wide range of stakeholders

• Systems thinker focused on rootcause analysis and durable fixes
• Calm and effective under pressure, especially during highseverity incidents
• Curious, datadriven, and committed to continuous improvement

• Experience operating or supporting systems using technologies such as MongoDB, ZooKeeper, and RabbitMQ
• Background in performance tuning and scalability optimization of Java services
• Experience setting or influencing engineering standards at the organization level
• Prior involvement in evolving SRE or platform practices in a growing engineering organization
• Experience designing, operating, or scaling systems in cloud environments such as AWS (preferred), including familiarity with core services, networking models, and reliability features

The Principal SRE role is critical to ensuring our platform continues to meet the reliability expectations of our customers as we grow. Your work will have a broad and lasting impact-not only on individual systems, but on how reliability and operational excellence are approached across engineering.
