Principal Platform Engineer

This is your opportunity to influence architectural strategy to shape the future of a monolithic product transformation

You’ll play a key role in shaping how technology enables business success at scale. As a Solution Architect, you will design and guide solutions that deliver measurable value through modern, scalable, and secure architecture.

You’ll bring strong technical capability, strategic insight, and the confidence to influence decisions and guide teams toward effective outcomes.

What you’ll be responsible for:

- Designing modern, cloud-native solutions on AWS that are scalable, secure, and aligned with enterprise goals.

- Applying MACH (Microservices, API‑first, Cloud native, Headless) and composable architecture principles to enable modular, future‑ready platforms.

- Leading end‑to‑end technical design

- Defining integration patterns using event‑driven and serverless architectures (Lambda, EventBridge, Step Functions) that improve performance and resilience.

- Translating business and functional requirements into practical, well‑architected solutions using TypeScript, Node.js or Python, and modern development frameworks.

- Guiding engineering teams through architectural decisions, providing hands‑on support, design reviews, and technical mentoring.

- Collaborating with product and delivery teams to balance speed, stability, and scalability in every solution.

- Staying current with emerging cloud and architecture trends – such as data mesh, API‑led integration, and event streaming – and applying them pragmatically where they add value.

What you’ll bring to the role:

- Your proven experience as a Solution Architect or Senior Engineer designing and delivering enterprise or platform‑scale solutions.

- Your deep understanding of modern architecture principles, including MACH (Microservices, API‑first, Cloud‑native, Headless) and composable design.

- Your hands‑on experience applying Hexagonal Architecture, Event‑Driven Architecture, and Domain‑Driven Design to build scalable, maintainable systems.

- Your technical capability across TypeScript, Node.js, and modern programming frameworks, with the ability to design and review high‑quality code.

- Your practical knowledge of AWS and serverless environments (e.g. Lambda, API Gateway, and EventBridge).

- Your proven success in guiding teams through design decisions and mentoring engineers to deliver well‑architected solutions.
