Why This Role Matters

SDET (Software Development Engineers in Test) engineers perform and participate in application development and testing, ensuring continuous quality and testability of code throughout the software development lifecycle. We build quality within the software development process through automated testing suites, providing comprehensive support from code development to functionality, and we live on the leading edge of system and component design, developing solutions that serve millions of users and businesses all over the world.

The SDET Manager brings this to life by contributing to technology development and decision-making, and guiding the work of SDET engineers and teams. This person will be joining at a time of growth, not only within a single team but across Vonage API; they will therefore need to be prepared and experienced to scale both processes and teams.

Your Key Responsibilities

• Lead, mentor, and scale a high-performing team of SDETs to successfully deliver on ambitious product roadmaps on our Messaging API team.
• Drive the development and execution of robust testing strategies for current and future product releases, ensuring comprehensive coverage of both functional and non-functional requirements.
• Treat AI-assisted engineering as a core part of modern software practice, leveraging AI tools to enhance design, coding, testing, troubleshooting, and documentation, while guiding the team in adopting effective patterns and evolving best practices for AI-enabled ways of working.
• Collaborate closely with product and engineering teams to design, develop, and optimise advanced test automation frameworks and maintain scalable, reliable data sets.
• Establish, track, and analyse quality and effectiveness metrics to inform decision-making, support continuous improvement, and ensure the highest standards of software quality.
• Proactively diagnose technical issues, report defects, and propose implementable solutions to prevent recurrence and improve product stability.
• Foster a culture of quality by developing and promoting processes that educate and empower engineers at all levels to write higher quality, testable software.
• Assess, optimise, and elevate current testing procedures and processes for efficiency, scalability, and alignment with business needs.
• Drive the implementation of non-functional testing strategies, including scalability, redundancy, chaos engineering, and automation, in cloud and hybrid/cloud-native environments.
• Partner with product and business managers to translate software requirements and technical architectures into actionable, measurable, and testable criteria.

What You'll Bring

Required:

• Proven engineering leadership experience, with a track record of leading and scaling teams of 10 or more engineers.
