We are looking for an experienced Engineering Team Lead to lead a key Mobile Software Engineering team in Toronto.

We believe in enablement, full accountability, empowerment, and collaboration. Our ideal candidate will foster an environment where team members are enabled with the right resources, fully accountable for their areas of responsibility, empowered to make decisions, and encouraged to collaborate effectively across teams and departments.

What you will be doing:

As a Team Lead at Semperis, you will be an essential member of our Engineering team, managing and leading a dedicated team of mobile developers to shape the architecture and delivery of our mobile applications. You will take full ownership of the mobile app lifecycle—from design and development to deployment on the App Store and Google Play—ensuring a secure, high-performing, and user-friendly experience.

You will collaborate closely with cross-functional teams including Product Management, UX/UI Design, and Backend Engineering to define and execute the mobile roadmap. Your leadership will be instrumental in driving technical excellence, fostering innovation, and maintaining high standards of quality and security.

You will be expected to demonstrate a high level of creativity and innovation, thrive in high-pressure environments, and possess strong communication and interpersonal skills. A solid foundation in software development, along with the ability to manage deadlines and apply analytical thinking to complex challenges, will be essential to your success in this role.

Key Responsibilities:

• Recruit, manage, coach, develop, and retain mobile engineering talent. Build and maintain a strong team culture focused on accountability, growth, and continuous learning.

• Lead ongoing mobile app development, including architecture, technical analysis, design, and implementation, following Agile SDLC and Scrum methodologies. Collaborate closely with Product Management, UX/UI, and other engineering teams to ensure successful feature delivery, deployment to the App Store and Google Play, and post-release operations.

• Facilitate the evolution of mobile product architecture, ensuring scalability, maintainability, and optimal performance. Contribute to defining the technical roadmap for the mobile application, driving its implementation, iteration, and long-term vision.

• Plan and lead mobile product releases, define clear milestones and deliverables, and track progress against schedule and budget. Facilitate coordination across related backend services and shared platform components. Define and report on relevant SDLC KPIs and mobile-specific metrics such as stability, crash rate, performance, and release cadence.

• Maintain and improve formal development processes within a team using company-wide standard tools to achieve full transparency and traceability.

• Drive product quality improvements through technical excellence, mobile performance optimization, security best practices, and modern software development standards. Ensure that testing, monitoring, and continuous integration are embedded into every stage of the mobile development process.

• Partner closely with Product Management to translate business needs into actionable technical objectives, proactively identifying opportunities to improve the user experience and application reliability.

• Act as a key technical liaison across departments — collaborating with product, security, and backend teams — to define and deliver high-quality, secure, and user-centric mobile applications.

• Ensure direct reports and the entire team have appropriate training and tools for maximum development productivity and velocity.

• Participate in the development and evolution of functional processes and drive Agile and Scrum process evolution and organizational change.

• Keep up to date with mobile technology trends, frameworks, and app store guidelines. Identify relevant innovations and champion their adoption within the team, where they can provide tangible product or process benefits.

What you will bring:

• 2 + years of experience managing mobile or software engineers.

• 5+ years of hands-on experience in mobile app development (React Native, Swift, Kotlin, or similar).

• Proven track record of deploying and maintaining mobile applications on both the Apple App Store and Google Play Store.

• Strong understanding of mobile architecture patterns (MVVM, Clean Architecture, modular design).

• Experience integrating mobile apps with cloud backends (Azure, AWS, GCP).

• A leadership style that combines mentoring, feedback, and empowerment to help developers grow.

• Bachelor’s degree in Computer Science or related field (or equivalent experience)

• Experience with modern software development processes (CI/CD, DevOps, microservices, Agile Scrum)

• Strong proactive leadership skills, ability to organize, motivate and inspire teams to achieve great results.

• Collaboration and conflict resolution skills.

• Excellent written and oral communication skills.

• Ability to translate business requirements into sound technical solutions, conceive, build, and deliver end-to-end solutions and communicate these solutions with peer organizations.

• Strong technical and understanding of software engineering concepts

• Proficiency in programming languages, frameworks, and tools used for software development

Bonus Points:

• Knowledge in the Enterprise Identity domain

• Understanding of security best practices for enterprise software

• Experience with security-focused or enterprise-grade mobile apps.

• Understanding of mobile MDM and compliance policies.

• Hands-on experience with the TypeScript + React Native ecosystem. (optional)
