The Ideal Candidate

The Lead Software Engineer: Cloud Modernisation will play a key role in advancing Entersekt’s transition toward cloud-ready and cloud-native architectures across the company’s SaaS product suite. This role combines senior technical leadership with hands-on engineering delivery.

You are an experienced engineer who is comfortable working directly within complex production codebases while also shaping architectural direction and modernisation strategy. You bring a pragmatic mindset when working with legacy systems and understand how to balance performance, cost efficiency, operational reliability, and delivery timelines when introducing cloud-native patterns.

The successful candidate will guide the modernisation of existing systems by introducing scalable architecture patterns, automation, and operational improvements while partnering closely with product engineering, platform engineering, DevOps, security, compliance, and product management teams.

Initial focus for this role will be the modernisation of Entersekt’s 3DS product suite, with patterns, architectural approaches, and enablement efforts expected to scale across the broader SaaS platform over time.

The Role

This is a senior individual contributor role operating at Lead Engineer level. The role combines architectural leadership with hands-on engineering execution and is responsible for defining and delivering the modernisation roadmap for key product systems.

The Lead Software Engineer will assess previous generation (heritage) components, design target-state architecture, and implement modernisation improvements directly in product codebases. The role will introduce modern engineering practices and cloud-native patterns while establishing guardrails, reference implementations, and repeatable approaches that product teams can adopt.

The position plays an important role in enabling a scalable SaaS operating model by improving automation, observability, deployment consistency, and tenant lifecycle management. Through close collaboration with engineering and platform teams, the role will help accelerate cloud-native delivery while maintaining strong operational, security, and regulatory standards.
