Mission Statement & Summary
As a Senior Site Reliability Engineer, you'll sit at the intersection of software engineering and operations, driving reliability, performance, automation, and resilience across our technology estate.
This is an opportunity to shape the future of our platform rather than simply maintain it. You'll work alongside talented engineers, influence technical direction, and champion modern reliability practices that enable teams to move faster with confidence. If you're passionate about solving complex problems, eliminating toil through automation, and creating systems that are resilient by design, we'd love to hear from you.
How you'll contribute
Lead initiatives that improve platform reliability, scalability, and operational excellence.
Design and deliver automation solutions that reduce manual effort and accelerate engineering teams.
Develop observability capabilities, enabling proactive monitoring and faster incident resolution.
You will facilitate incident management, driving root cause analysis and continuous improvement.
You'll collaborate with engineering teams to embed reliability, resilience, and performance into every stage of delivery.
We're looking for these essential skills
Software engineering and design experience (preferably Typescript or .net/C#), to build and improve production systems, apply solid design principles, and contribute directly to codebases to deliver reliable, scalable, and maintainable services.
The ability to automate infrastructure, operational processes, and deployments using modern engineering practices.
Experience building effective observability solutions, including monitoring, logging, alerting, and tracing.
Strong problem-solving skills with the ability to diagnose and resolve complex production issues.
The ability to influence technical decisions and collaborate effectively across engineering and business teams.
It's a plus if you also have these skills
Experience operating Kubernetes-based platforms at scale.
Knowledge of Infrastructure as Code tools and cloud platform services.
Experience implementing Site Reliability Engineering principles, including SLOs, SLIs, and error budgets.
Familiarity with security, compliance, and resilience best practices within cloud environments.
Experience mentoring engineers and helping teams adopt modern operational and reliability practices.
At NewDay, we value all types of diversity. We’re an equal opportunity employer and believe that our differences create a vibrant, authentic working culture. We want all our colleagues to feel able to bring their whole selves to work. We don’t discriminate on the basis of protected characteristics or identities. We make sure that every job is crafted to be inclusive and that people with disabilities or caring responsibilities can take part in the application and interview process.
Tell us if you need accommodations: We’ll put reasonable adjustments in place to support you.
We work with Textio to make our job design and hiring inclusive.
