Esper partners with the leading mobile device hardware manufacturers, solution providers, and distributors globally.

What You'll Be Doing

• Understand product requirements, architecture, and customer workflows and design effective validation strategies.
• Build and scale API/UI automation frameworks and reusable engineering guardrails across DRE.
• Develop automated coverage for new product features, customer workflows, regressions, and production issues.
• Perform release validation and continuously reduce the manual effort required for releases.
• Move validation earlier in the SDLC by integrating automated checks into development, PR, and CI/CD workflows.
• Build developer tooling that provides fast and actionable feedback to engineering teams.
• Expand automation coverage across Windows, Linux, Airwave, and other areas with limited current coverage.
• Convert customer and requirement scenarios into reusable automated validation contracts.
• Investigate failures across UI, APIs, backend services, logs, databases, containers, devices, and environments.
• Debug backend/cloud issues and contribute code fixes when required.
• Use AI coding tools and agents to accelerate development, automation, test generation, debugging, failure analysis, and maintenance.
• Improve the reliability, maintainability, and execution speed of existing automation.
• Contribute to Hard Commits, P3s, PFRs, backend/cloud engineering, and other DRE priorities as required.
• Partner with Engineering, Product, and Release teams to improve release confidence and developer velocity.

Skills & Abilities (Required)

3–5 years of relevant software testing/automation engineering experience.

• Strong software testing fundamentals and ability to design comprehensive validation strategies.
• Strong programming fundamentals in Java, Python, JavaScript/TypeScript, Go, or equivalent.
• Hands-on API testing and API automation experience.
• Hands-on UI automation experience using Playwright, Selenium, or equivalent.
• Experience designing/building reusable automation frameworks or test infrastructure.
• Good understanding of backend systems, APIs, databases, asynchronous processing, retries, queues, and failure handling.
• Ability to read, debug, modify, and test existing backend code.
• Strong debugging/RCA skills across application, API, backend, logs, database, automation, and environment layers.
• Experience integrating automated validation into PR and CI/CD workflows.
• Git/GitHub and modern software-development workflow experience.
• Ability and willingness to use AI-assisted development tools as part of day-to-day engineering.
• Strong ownership, problem-solving, and communication skills.

Bonus Points if You Have

• Hands-on backend/cloud development experience.
• Docker/Kubernetes experience.
• SQL/database debugging.
• Windows/Linux automation.
• Device-management or enterprise SaaS experience.
• Performance, reliability, scalability, or resilience testing.
• Internal developer-tooling experience.
• Observability/logging/metrics/tracing experience.
• Experience building AI/LLM/agent-assisted engineering workflows.

What We Think Makes Us Special

High ownership with direct impact on product and customer reliability.

• Quality is treated as an engineering responsibility rather than a downstream testing activity.
• Opportunity to influence how validation is built into the entire development lifecycle.
• Work across testing, automation, backend/cloud, device workflows, and developer tooling.
• AI-first engineering environment with opportunities to use AI for real development and quality problems.
• Ability to build reusable systems and guardrails consumed by multiple engineering teams.
• Direct impact on release confidence and engineering velocity.
