Job Description
Responsibilities
1. Software development & architecture
• Design, build and maintain production-grade backend services and APIs, writing clean, well-tested, maintainable code and owning features from design through to production.
• Define the software architecture for new and existing systems — service boundaries, API contracts, integration and event-driven patterns — documented through architecture decision records, and review human- and agent-authored code for design quality.
• Design data models and database schemas (relational and NoSQL, e.g. PostgreSQL / Aurora, DynamoDB) and optimise database performance through query tuning, indexing, partitioning and caching.
• Enhance application security — secure coding practices, authentication and authorisation (OAuth 2.0 / OIDC), input validation, secrets handling, and remediation of OWASP Top 10 and SAST / DAST / SCA findings.
2. Cloud platform architecture, infrastructure as code & cost
• Design and own STYL’s AWS landing zones and shared platform — multi-account organisation, networking (VPC, PrivateLink), identity and environment strategy.
• Define all infrastructure as code (Terraform and/or AWS CDK / CloudFormation) as reusable, versioned modules that both engineers and AI agents can consume safely.
• Run and evolve the container and serverless runtime (Amazon EKS / ECS, Lambda) and the event backbone (EventBridge, SQS / SNS, MSK) that underpins our event-driven architecture.
• Estimate the cloud cost of new solutions and architecture options up front, and optimise cost at the platform level, right-sizing, shared infrastructure, Savings Plans / reserved capacity and cost visibility.
3. CI/CD, release engineering & Git workflow
• Own the CI/CD pipelines (GitLab CI, ArgoCD or equivalent GitOps) that build, test, scan and promote every change, human- or agent-authored.
• Encode quality gates in the pipeline (SonarQube, SAST / SCA, policy-as-code) so the Human Governance Gate reviews evidence rather than re-running checks by hand.
• Enable safe, frequent releases through progressive delivery, automated rollback and clean branching strategies across parallel production lines.
4. Technical leadership & continuous adaptation
• Act as the senior technical voice for architecture and platform decisions: write architecture decision records, review designs and mentor engineers and Fleet Commanders on engineering and platform practice.
• Evaluate and adopt emerging infrastructure, AI-ops and agent tooling, and automate away recurring toil.
Qualifications
• Experience — 6+ years of professional software development, including at least 3 years designing software architecture for production systems, plus substantial hands-on DevOps / platform engineering experience running workloads on AWS.
• Educational foundation — Bachelor& degree in Computer Science, Software Engineering or a related technical discipline.
• Software engineering & architecture — writes production-quality code in at least one general-purpose language (Java, Python, Go or TypeScript); strong in design patterns, testing and code review; able to design service architectures, APIs and integration patterns and articulate their trade-offs.
• Database design & optimisation — solid relational data modelling and SQL; experience with performance tuning (query plans, indexing, partitioning) and with choosing between relational, NoSQL and caching stores.
• Application security — applies secure coding practices and OWASP guidance; understands authentication and authorisation (OAuth 2.0 / OIDC), encryption and secrets management, and can triage and fix findings from SAST / DAST / SCA tools.
• Distributed & event-driven systems — understands messaging, idempotency, back-pressure, failure modes and the scaling and resilience trade-offs behind a platform design.
• Cloud, DevOps & infrastructure — strong hands-on experience with AWS core services (networking, IAM, compute, storage, databases) and infrastructure as code (Terraform and/or CDK); strong with containers and Kubernetes; fluent in Linux, Git and CI/CD design.
• A supervisor& mindset toward AI — hands-on with AI-assisted coding tools and multi-agent workflows; able to judge agent-generated code and infrastructure changes critically and design guardrails that make them safe.
• Multi-agent systems & LLM platforms – experience building and deploying multi-agent systems to production; familiar with major LLM providers (e.g. Anthropic, OpenAI, Amazon Bedrock) and LLM gateways (e.g. LiteLLM, Portkey or equivalent) for model routing, rate limiting, fallback and cost control.
• Leadership & communication — able to drive technical direction across squads, explain trade-offs clearly to engineers and stakeholders, and mentor others.
• AWS certification — required to apply; candidates must hold a current AWS Associate-level certification or higher — Solutions Architect — Associate (SAA-C03), Developer — Associate (DVA-C02) or SysOps Administrator / CloudOps Engineer — Associate. A Professional-level certification (DevOps Engineer — Professional or Solutions Architect — Professional) is a strong advantage.
