Principal Software Engineer (SRE)-Onshape-Remote US.
About the Role
Onshape’s Site Reliability Engineering team is looking for a Principal Software Engineer to play a critical role in ensuring the long‑term reliability, scalability, and operational excellence of our platform.
As a Principal Software Engineer, you will operate with a high degree of autonomy and influence. You will lead complex, cross‑organization 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 Software Engineer, you will help protect customer trust by driving reliability across the entire system lifecycle.
This role is ideal for engineers who enjoy solving ambiguous, high‑impact problems at scale, influencing system design across teams, and raising the reliability bar for an entire organization.
What You’ll Do:
Own Reliability at Scale
Lead design, implementation, and evolution of reliability, availability, and resiliency strategies for large‑scale distributed systems written primarily in Java
Apply deep experience operating complex, distributed systems to guide architectural decisions, reliability strategies, and long‑term 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
Drive Operational Excellence
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 long‑term remediation
Champion blameless post-incident reviews and ensure learnings translate into durable system improvements
Reduce Toil Through Engineering
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 Java‑based services and their operational needs
Raise the bar on monitoring, alerting, and SLO/SLI adoption across systems
Lead Through Influence and Collaboration
Partner deeply with product engineers, architects, and engineering leadership to ensure reliability and operability are first‑class 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
Shape Strategy and Direction
Contribute to longer‑term 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
What We’re Looking For
Required Experience & Expertise
US Citizenship or Permanent Residents only due to ITAR requirements.
Ability to work east coast (EST) hours. And be available for on-call rotation once every 10 weeks.
10+ 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 high‑quality, maintainable code
Technical Strength
Expert understanding of incident management, service reliability, and performance engineering
Strong hands‑on experience with observability (metrics, logs, traces), capacity planning, and SLO‑driven reliability
Deep familiarity with modern cloud‑based infrastructure, CI/CD pipelines, and infrastructure‑as‑code practices
Ability to reason about failure modes across application, data, and infrastructure layers
Leadership & Influence
Demonstrated ability to lead complex initiatives that span teams and organizational boundaries
Comfortable making high‑impact technical decisions in ambiguous environments
Strong communicator who can influence design and operational decisions across a wide range of stakeholders
Mindset
Systems thinker focused on root‑cause analysis and durable fixes
Calm and effective under pressure, especially during high‑severity incidents
Curious, data‑driven, and committed to continuous improvement
Nice to Have
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
Why This Role Matters:
The Principal Software Engineer 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.
