Role Overview
The Team is looking for a Senior Software Engineer in
Test (SDET) to help build and assure the next generation of intelligent,
agentic products and platforms. This is a hands -on senior engineering role for someone
who combines deep automation expertise with strong software engineering
fundamentals and practical experience testing AI -powered and agent -based
systems in production -grade environments.
This role is idóneo for a builder who enjoys solving complex quality challenges,
designing scalable automation strategies, and raising the engineering bar
across teams. We are particularly interested in candidates who can apply
innovative thinking, strong ownership, and modern quality engineering practices
to validate agentic applications, LLM -powered workflows, APIs, user journeys,
and end -to -end platform reliability.
We are seeking a talented Senior Software
Development Engineer in Test (SDET) to define and implement an effective
automation and quality strategy within an Agile team. This role will validate
application functionality, resilience, and business outcomes using modern
testing methodologies, strong engineering discipline, and best practices in
continuous integration and delivery

Requirements Role:
• Own end -to -end quality engineering for agentic
applications, intelligent workflows, APIs, user interfaces, and supporting
platform services.
• Design, develop, and maintain robust
automation frameworks for UI, API, integration, regression, and system -level
testing.
• Define test strategies for AI and agent -based
systems, including workflow validation, response quality, tool usage,
guardrails, reliability, and failure handling.
• Build automated quality gates for CI/CD
pipelines and ensure high -confidence releases through continuous testing.
• Partner closely with software engineers,
product managers, architects, and data/AI teams to ensure quality is built in




from design through production.
• Create meaningful test data, validate edge
cases, identify defects early, and drive root cause analysis through to
resolution.
• Evaluate non -functional characteristics such
as performance, reliability, observability, resilience, and scalability.
• Contribute innovative ideas that improve
testability, developer productivity, release confidence, and engineering
effectiveness.
• Demonstrate strong ownership by proactively
identifying gaps, driving improvements, and mentoring team members on
automation and quality best practices.
About You
• Strong experience in software test automation,
automation framework design, and code quality practices.
• Proven ability to test modern distributed
systems, APIs, event -driven architectures, and user -facing applications.
• Experience validating AI -enabled or agentic
applications, including prompt/workflow validation, output quality assessment,
and scenario -based testing.
• Strong understanding of Agile development,
shift -left testing, continuous integration, and continuous delivery.
• Comfortable working across ambiguity and
applying innovative thinking to solve new and evolving quality challenges.
• Strong communication, collaboration, and
stakeholder management skills, with a bias for action and accountability.
Technical Skills
• Strong programming skills in Java, Python, or
similar languages used for automation and test engineering.
• Hands -on experience with API and UI automation
frameworks such as Playwright, Selenium, Cypress,



REST Assured, or equivalent.
• Experience integrating automated tests into
CI/CD pipelines and quality gates.
• Understanding of test approaches for LLMs,
retrieval workflows, agent orchestration, and non -deterministic systems is
highly desirable.
• Familiarity with observability, logging, test
data management, performance testing, and service virtualization is a plus.
Leadership & Mindset
• Innovative thinker who challenges conventional
approaches and introduces better ways to assure quality at scale.
• Strong sense of ownership, accountability, and
follow -through from test strategy through delivery outcomes.
• Able to influence quality culture across teams
and mentor others in modern automation and engineering excellence.
