With a global footprint and deep local insight, Software at Scale delivers cutting-edge technology solutions that power mission-critical platforms. We solve complex engineering challenges at scale, driving quality, performance, and resilience through the strength of our people.
The Role & The Challenge
We are seeking an exceptional, highly proactive Senior Sitecore Engineer who thrives in a high-trust, fully empowered environment. Make no mistake: this is a deeply hands-on, heavy-coding execution role. We are not looking for a passive ticket-taker or a pure slide-deck architect.
Your primary mandate will be spearheading the architecture and ground-up development of a brand-new, enterprise-grade digital platform using the latest composable Sitecore technologies. We do not micromanage, nor do we hand out pre-packaged answers. You will step into an environment where you are expected to take complete technical ownership, write production-grade code daily, and creatively solve deep architectural puzzles to get this new platform off the ground.
You are not just a solo brilliant coder; you are a foundational team player. You will lead by example, establishing engineering baselines, and naturally providing the technical mentorship needed to lift the engineering capabilities of the squads around you.
Key Responsibilities
-
Greenfield Platform Build: Act as the lead hands-on engineer designing, coding, and launching a brand-new enterprise platform from scratch using modern Sitecore technologies (XM Cloud / Sitecore 10+).
-
Deep Sitecore Integration: Architect and write code for advanced Sitecore implementations involving xConnect, xDB, and complex custom Solr search indexing strategies.
-
Headless & Composable Delivery: Build the new platform using a headless architecture, heavily utilising Sitecore JSS, Next.js, and integrating composable SaaS products like Sitecore Content Hub (DAM/CMP) and Sitecore CDP & Personalize.
-
Technical Leadership & Team Uplift: Actively mentor and elevate mid-level engineers through collaborative code reviews, pair programming, and architectural whiteboard sessions, enforcing strict Helix architecture principles.
-
Backend System Design: Write robust C# / .NET Core backend integrations linking the new Sitecore platform with external CRM, commerce, and bespoke microservices via REST/GraphQL APIs.
-
DevOps & Serialization: Implement and manage strict Sitecore item serialization (using Sitecore CLI / SCS, Unicorn, or TDS) and develop frictionless CI/CD pipelines for automated, containerised deployments.
-
Cloud-Native Deployment: Leverage Azure or AWS native services to deploy highly available, horizontally scalable infrastructure for the new platform to handle massive global traffic spikes.
What You Bring
-
Hands-On Execution Mindset: You are a practitioner who loves to get into the codebase. You have a proven history of independently researching architectural trade-offs and directly writing the code to build complex systems from the ground up.
-
Deep Sitecore Mastery: Strict, mandatory commercial experience with advanced Sitecore components. You must deeply understand the Sitecore pipeline, dependency injection, event handlers, xConnect, and xDB architecture.
-
Headless & Composable Expertise: Mandatory commercial experience designing and building headless solutions using Sitecore JSS (React/Next.js). Hands-on experience with Sitecore XM Cloud, Content Hub, or Sitecore CDP is highly desirable.
-
Architecture & Standards: Strict adherence to Sitecore Helix principles and mastery of Sitecore serialization tools (SCS, Unicorn, or TDS).
-
.NET Core Expertise: Deep underlying expertise in C# and the latest .NET Core frameworks.
-
Security & Performance: A strong track record of building secure, performant web applications, implementing effective caching strategies (Redis, CDN), and securing sensitive customer data.
-
Communication: Strong communication skills and a collaborative, execution-driven approach to solving enterprise digital problems.
What We Offer
- The unique opportunity to lead the hands-on engineering of a massive, greenfield Sitecore platform build.
- Meaningful work across complex, enterprise-grade digital experience platforms.
- Clear growth pathways from Senior to Staff and beyond.
- A low-ceremony, delivery-focused environment that values engineers who own outcomes.
- Competitive remuneration and benefits.
