We are looking for an exceptional SDET Manager who will be a key contributor on the Midnight team developing leading edge technology in one of the most exciting fields in the world. Midnight is a regulatory-friendly data protection-based blockchain that safeguards sensitive commercial and personal data. Midnight protects fundamental freedoms of association, commerce, and expression for developers, companies, and individuals. Midnight use cases utilize a novel data protection-first programming model and ZK proofs while operating as a Cardano sidechain.

As the SDET Manager, your role will be pivotal in driving the design, planning, scripting, execution, and reporting of software testing activities across all releases of the Midnight platform. Leading a highly skilled team of Software Engineers in Test, you will collaborate closely with developers, product owners, and other stakeholders throughout the software development life cycle (SDLC). While this role does have responsibilities of people management with high-level direction and planning, technical leadership will be a primary focus as the adoption of common standards, methods and tooling across the team and the wider organization is a necessity. Your primary responsibilities will include overseeing test iterations, troubleshooting issues, and coordinating defect resolution. Your contributions will be instrumental in ensuring smooth software operation and meeting client requirements during product launches.

  • Conduct thorough root cause analysis of defects and work closely with development teams to drive timely resolutions.
  • Stay up-to-date with the latest advancements in blockchain technology and testing methodologies, and proactively apply them to improve our testing processes.
  • Provide leadership in driving a quality-focused culture, promoting innovation, and fostering collaboration within the testing team and across the organization.
  • Collaborate with stakeholders to define and track key quality metrics, ensuring visibility into the effectiveness of our testing efforts.
  • Participate in code reviews, providing valuable feedback on testability, code quality, and adherence to best practices.
