What does a Sr Reliability Engineer do?

A Sr Reliability Engineer is responsible for ensuring that products, systems, or processes operate reliably and efficiently over their expected lifecycle. They analyze failure data, develop reliability test plans, and implement strategies to predict and prevent failures. Their role often involves collaborating with design, manufacturing, and maintenance teams to improve product quality and reduce downtime. Additionally, they may use reliability modeling tools and statistical techniques to assess risk and recommend improvements. This position typically requires advanced engineering knowledge and experience in reliability engineering principles.

What are the key skills and qualifications needed to thrive as a Sr Reliability Engineer?

To thrive as a Sr Reliability Engineer, you need expertise in reliability engineering principles, root cause analysis, and a relevant engineering degree, often with several years of industry experience. Familiarity with reliability software (such as ReliaSoft or Minitab), maintenance management systems, and certifications like Certified Reliability Engineer (CRE) are commonly required. Strong problem-solving abilities, proactive communication, and leadership skills help you drive reliability initiatives and collaborate across teams. These competencies are vital to ensure equipment uptime, reduce failures, and improve operational efficiency in complex industrial environments.

How does a Sr Reliability Engineer typically collaborate with cross-functional teams to improve system reliability?

As a Sr Reliability Engineer, you will regularly work alongside operations, development, and QA teams to identify potential reliability risks and implement solutions. This often involves facilitating root cause analyses after incidents, sharing best practices, and leading reliability-focused design reviews. Effective communication and the ability to translate complex technical findings into actionable recommendations are key, as your insights directly influence infrastructure and product decisions. This collaborative approach helps foster a culture of reliability across the organization.

What is the difference between Sr Reliability Engineer vs Reliability Engineer?

AspectSr Reliability EngineerReliability Engineer
CredentialsBachelor's or higher in engineering, certifications like CRE or Six Sigma often preferredBachelor's degree in engineering or related field, similar certifications
Work EnvironmentTypically in manufacturing, energy, or tech industries focusing on system reliability and failure analysisSimilar industries, focusing on designing, testing, and improving product or system reliability
Employer UsageUsed in companies seeking experienced engineers to lead reliability projectsUsed for entry to mid-level roles focused on reliability assessments

The main difference is experience level and responsibility. Sr Reliability Engineers often lead projects and have more advanced certifications, while Reliability Engineers focus on supporting reliability tasks. Both roles require similar credentials and work in comparable environments, but the senior role involves more leadership and strategic planning.

Are senior reliability engineers in demand?

Senior reliability engineers are in high demand across industries such as manufacturing, energy, and technology due to their expertise in system maintenance, failure analysis, and predictive modeling. Companies seek experienced professionals with skills in data analysis, reliability tools, and certifications like Six Sigma or RCM to improve equipment uptime and reduce costs.

How much do Sr Reliability Engineers get paid?

Senior Reliability Engineers typically earn between $90,000 and $130,000 annually, depending on experience, industry, and location. They often have expertise in systems analysis, failure modes, and reliability tools like FMEA and RCM, which can influence compensation levels.

Job description

AgileEngine is an Inc. 5000 company that creates award-winning software for Fortune 500 brands and trailblazing startups across 17+ industries. We rank among the leaders in areas like application development and AI/ML, and our people-first culture has earned us multiple Best Place to Work awards.

WHY JOIN US
If you're looking for a place to grow, make an impact, and work with people who care, we'd love to meet you!

ABOUT THE ROLE
We are looking for a Senior Performance Engineer to own and lead an enterprise-wide Performance Engineering function as a horizontal shared service across a global QSR digital ecosystem including web, mobile, kiosk, POS, loyalty, and payments systems. You will design and execute load, stress, and endurance tests using JMeter, k6, or similar tools, integrate automated performance validation into Azure DevOps CI/CD pipelines, partner with SRE and DevOps teams on chaos engineering experiments, and leverage AI-assisted workflows for performance planning and results triage.

WHAT YOU WILL DO
- Own the enterprise Performance Engineering charter as a horizontal shared service, establishing engagement models and SDLC performance-readiness standards.
- Design, script, execute, and report performance tests (load, stress, endurance, scalability) across high-volume ordering, kiosk, POS, loyalty, and payment flows.
- Identify and resolve bottlenecks across application, database, messaging, and infrastructure layers using observability signals (e.g., Dynatrace).
- Embed automated performance validation into CI/CD pipelines (e.g., Azure DevOps) with baseline and threshold gating.
- Partner with SRE/DevOps teams to define reliability targets and run controlled chaos-engineering experiments (fault/latency injection, dependency degradation).
- Define performance-readiness criteria, provide evidence-based go/no-go release recommendations, and assist with production performance-incident resolution.
- Integrate AI-assisted workflows into performance planning, test-design acceleration, and results triage while maintaining AI-consumable artifacts and safety guardrails.

MUST HAVES
- You must be authorized to work for ANY employer in the US (e.g., Green card holders, TN visa holders, GC EAD, H4 EAD, U4U with EAD), as we are unable to sponsor or take over employment visa sponsorship at this time;
- 4+ years of experience in performance engineering or non-functional testing at enterprise scale.
- Hands-on expertise with performance testing tools (e.g., JMeter, k6, LoadRunner, NeoLoad, or OctoPerf).
- Experience with enterprise observability and cloud monitoring platforms (e.g., Dynatrace).
- Demonstrated experience integrating automated performance validation into CI/CD pipelines (e.g., Azure DevOps).
- Scripting and automation proficiency in Java, JavaScript, or Python.
- Hands-on engineering experience in cloud environments (AWS or Azure).
- Hands-on experience using AI-assisted engineering tools, including reviewing and validating AI-generated output.
- Strong communication and stakeholder leadership skills with the ability to translate technical findings into clear business impact.
- Upper-intermediate English level.

NICE TO HAVES
- Direct experience partnering with SRE/DevOps practices on chaos engineering (fault/latency injection and dependency degradation testing).
- Prior experience supporting digital platforms within quick-service-restaurant (QSR), retail, or high-volume transactional ordering ecosystems.
- Experience maintaining AI-consumable artifacts (NFRs, workload models, baselines, thresholds) and defining AI guardrails.

PERKS AND BENEFITS
- Growth without limits: build your skills through mentorship, internal TechTalks, challenging projects, and a dedicated annual learning budget
- Competitive compensation: get recognition that reflects your skills and impact, with regular performance and compensation reviews
- Flexibility: work 100% remotely with flexible hours that support focus, autonomy, and a healthy work rhythm
- Meaningful, modern projects: build impactful products using modern technologies alongside global teams and leading brands
- Collaborative culture: join a supportive environment with zero micromanagement where ideas are welcomed and contributions are recognized
- Well-being & support: access local well-being programs and people-focused support tailored to your location
