About the role
As a Technical Lead at SMG, you will lead a product-focused engineering squad while providing cross-platform architectural leadership across SMG’s product engineering organisation. You will own system and delivery decisions for your team’s platforms, ensure resilient cloud deployments and operational excellence, and partner with other Technical Leads to define, govern, and evolve consistent technical standards, operational practices, and tooling across SMG. This is a hands-on leadership role: you will design and validate architecture, unblock and mentor engineers, ensure the team delivers high-quality, secure, observable, and cost-efficient product outcomes, and directly line-manage engineers, including mentoring, performance reviews, and career development.
What you’ll do
- Work closely with the Product team to refine requirements and prepare them for specification through iterative discovery and grooming sessions.
- Ensure the engineering team produces clear, fit-for-purpose technical design specifications in a variety of formats (architecture diagrams, technical design specs, API specifications, data matrices/spreadsheets). Provide templates, guardrails, and review cycles so designs are consistent and development-ready.
- Play an active role in the platform re-architecture: help plan how we will scale platforms to meet future growth and new business models.
- Oversee development and help unblock technical challenges by contributing code, participating in debugging, and joining design pairings. Act to enable engineering autonomy and rapid delivery.
- Ensure our codebase follows best practices and establish high-quality code patterns, shared libraries, and reusable components to reduce duplication and increase consistency. Lead by example in code quality through code reviews and hands-on contribution.
- Conduct technical and architectural reviews that are light, time-boxed, and constructive to validate that designs are robust, maintainable, secure, and aligned with SMG Technical Principles. Use reviews to coach engineers and to make iterative improvements.
- Help drive delivery reliability and operational excellence: ensure CI/CD pipelines are defined, Infrastructure as Code is used where appropriate, deployment patterns (feature flags, canary/blue-green) are available, and observability (metrics, logs, traces), automated alerts, runbooks, and post-incident reviews are in place.
- Ensure production readiness for releases, working alongside the QA Lead to define pragmatic testing strategies and rollout plans; partner with SREs to optimise cost, scalability, and platform resilience across SMG’s platforms.
- Embed Security-by-Design into technical decisions: threat modelling, least-privilege IAM, secrets management, and compliance controls, in partnership with Security and Data teams.
- Work closely with other Technical Leads to agree and adopt best practices, tooling, and patterns across squads; participate in cross-lead forums and steward SMG Technical Principles and Standards to maintain consistency across platforms.
