Sr. Solutions Architect, Coalition Accelerator Builder, GNSD

The Coalition Accelerator Builder team is the conversion layer between qualified defence-cloud demand and reusable, deliverable capability. The NSD mission threads and field identify customer challenges and generate demand; this team turns that demand into proven accelerators that ProServe, partners, and regional teams can deliver repeatedly without a specialist in the room.

The accelerator portfolio includes C2CMA (Command and Control Cloud Mission Accelerator), Trusted Secure Enclaves, and CEGA (Cloud Edge Global Access), linked together by the AMF (AWS Mission Framework) to deliver holistically for the mission rather than as isolated point solutions.

You will be one of the first builder hires into this team. Your job is to build, prove, and scale the accelerator portfolio: helping build best-practice guidance and reference architectures, hands-on in the codebase, embedded in live customer delivery, and then codifying what works into repeatable approaches that the wider field can own.

How You Work: The Prove-Then-Scale Model

Your initial validation is direct involvement in customer delivery. You embed alongside ProServe and partner engineers on live engagements, contribute code, solve real deployment problems, and understand what breaks in production defence environments. You then extract that experience into repeatable, tested patterns: infrastructure-as-code, CI/CD pipelines, demo platforms, contribution guides, and enablement collateral. The credibility of everything you produce comes from having built it against real operational need, not in a lab.

What This Role Is NOT

This is not a traditional customer-facing SA role with occasional prototyping. It is a build role. You will write code, own pipelines, and maintain a codebase. Customer exposure comes through embedded delivery, not through pre-sales presentations. If your instinct is to architect on a whiteboard and hand off to someone else to implement, this is not the right fit.

Key job responsibilities
- Engineer and maintain accelerator codebases. Terraform, CI/CD pipelines, container orchestration, infrastructure-as-code. You own the shared core that every deployment depends on.
- Embed in live customer delivery. Work alongside ProServe and partner teams on funded engagements to validate patterns, fix what breaks, and build credibility for the approaches you will later scale.
- Build and maintain demo and reference platforms. Standing environments that prove the accelerators work, support sales conversations, and give partners a validated starting point. This includes environments demonstrating secure-by-design patterns to customers and accreditation bodies.
- Design and implement automated compliance validation tooling that maps deployed infrastructure to control frameworks (NATO, NCSC, national standards) and produces auditable evidence.
- Own contribution standards and code quality. Define how ProServe and partners contribute to the shared codebase. Review pull requests, enforce Architecture Decision Records, maintain architectural coherence across country-specific extensions.
- Create technical enablement collateral. Not marketing decks. Deployment guides, runbooks, architecture walkthroughs, security runbooks, accreditation evidence templates, and hands-on workshops that make non-specialist SAs, Tech BDs, and delivery teams self-sufficient.
- Drive roadmap delivery. Execute against the priorities set by the Product Owner and STL. Translate demand signal from the field into shipped capability.
- Interface across the collaboration model. Work with ProServe, partners, regional SAs, Tech BDs, and AWS Security. You are the bridge between the team that sets direction and the teams that deliver at scale.

About the team
Coalition Accelerator Engineering sits within GNSD and governs the accelerator portfolio that underpins the AWS defence-cloud go-to-market across allied nations. The team is deliberately small and high-leverage: it builds each capability once, to a standard that holds, and it becomes a repeatable delivery vehicle. You will work directly with the STL, Product Owner, and fellow engineers, and interface daily with BD, ProServe, and partner teams across multiple countries. Each accelerator compounds: what one nation builds, the next fields rather than rebuilds.
