Sr SRE

Our client is seeking a Senior Site Reliability Engineer to help define, lead, and continuously improve operational best practices using modern Site Reliability Engineering principles, with a strong emphasis on AWS-based cloud infrastructure.

This role partners closely with engineering, production support, and technology leadership to design, implement, and operate highly reliable, secure, scalable, and cost-effective systems supporting a complex application ecosystem and software delivery lifecycle.

The Senior SRE will influence cloud architecture decisions, lead complex infrastructure initiatives, and drive long-term improvements in reliability, observability, automation, and cost efficiency. This is a senior individual contributor role with broad technical ownership and organizational influence.

Key Responsibilities

• Contribute to the design, evolution, and operational health of a large-scale AWS environment, including architecture standards and best practices

• Design, implement, and optimize AWS-based infrastructure using services such as EC2, ECS/EKS, Lambda, RDS, S3, IAM, VPC, and CloudWatch

• Build and manage cloud infrastructure using Infrastructure as Code tools such as Terraform, CloudFormation, or equivalent

• Lead new platform implementations and major reliability initiatives as a subject-matter expert in AWS and SRE practices

• Monitor, analyze, and optimize cloud spend, balancing performance, reliability, and cost efficiency

• Apply and mature SRE principles to improve system availability, scalability, performance, security, and observability

• Design and implement automation to reduce operational toil and improve system efficiency

• Provide advanced operational support for cloud-hosted and hybrid platforms

• Define and improve monitoring, alerting, logging, and incident response practices

• Lead complex production incidents, perform root cause analysis, and drive corrective and preventive actions

• Mentor junior and mid-level engineers through technical guidance and best-practice leadership, without direct people management

• Collaborate with engineering, QA, security, and business teams to embed reliability throughout the software delivery lifecycle

• Ensure systems and data handling meet applicable legal, regulatory, and security requirements

• Improve production engineering processes including change and configuration management, observability, incident response, disaster recovery, capacity planning, performance tuning, and deployment automation

• Participate in a sustainable on-call rotation and help reduce alert fatigue over time

• Act as a change agent for long-term technical strategy, identifying risks, dependencies, and improvement opportunities

Required Qualifications

• Bachelor's degree in Computer Science, Information Systems, Engineering, or equivalent practical experience

• 7+ years of experience delivering technical solutions in production environments

• Three or more years of hands-on Site Reliability Engineering experience

• Extensive experience designing, operating, and scaling production AWS environments

• Strong expertise with Infrastructure as Code and modern cloud deployment patterns

• Proven ability to diagnose and resolve complex issues in distributed systems

• Experience leading incidents and driving post-incident improvements

• Ability to work independently, prioritize effectively, and manage multiple initiatives

• Strong written and verbal communication skills with both technical and non-technical stakeholders

Preferred Qualifications

• AWS certifications such as Solutions Architect, DevOps Engineer, or SysOps Administrator

• Experience working in regulated industries such as healthcare, financial services, or similar environments

• Familiarity with modern application stacks and supporting tools including CI/CD pipelines, version control systems, observability platforms, containerization, orchestration technologies, and identity and access management solutions

• Experience working in Agile or Scrum-based delivery environments

What Success Looks Like

• Production systems are stable, observable, and resilient

• Incidents are handled effectively and result in measurable reliability improvements

• Infrastructure scales predictably while remaining cost-conscious

• Engineering teams are supported by clear standards, automation, and reliability tooling

• Reliability is embedded into the delivery process rather than treated as an afterthought
