About Big Hand

Big Hand offers technology solutions for busy legal professionals that provide data and insights to increase value and profits. Through our expert knowledge and innovative technology, we enable our customers to achieve enhanced efficiency, better decision-making and harness their competitive edge.

We build with tomorrow in mind, transforming ideas into action and empowering our customers to succeed in a world of constant change. We make big happen for our customers.

We are a business driven by our values and have these at the centre of everything we do. Our Big Handers are dedicated to building a culture where We Win Together, We Love to Learn, We Do the Right Thing, We Own It and We Find the Fun.

Big Hand has been iteratively building its cloud-native SaaS capabilities in the last few years, and continues to raise the bar — maturing our microservices-based, event-driven architecture, expanding AI across our product portfolio, and building a richer set of shared cross-product platform capabilities that let our product engineering teams move faster and deliver more value.

AI is not a future ambition at Big Hand — it is already shaping our products and our roadmap is accelerating. Our goal is for every product to be AI-powered, and over the next 12–18 months every product engineering team will be building or integrating AI capabilities. The person joining this role will have a genuine opportunity to shape how we architect and deliver those frontier capabilities at scale.

Reporting to the Director of Architecture, you will take ownership of the architecture for one of our products, contribute to our cross-product platform, and own the standards and guardrails that give our product engineering teams the confidence to move fast without compromising on quality or customer outcomes. You will work closely with product teams, product engineering teams, the Architecture team, and our cloud engineering team to deliver architecture that is ambitious in vision and practical in delivery.

Product Architecture

• Define, evolve and deliver the architectural roadmap for your product area.

Cross-Product Architecture

• Own API contracts, service boundaries, data models and inter-service communication patterns within your product.
• Use your technical depth to solve the hardest problems from product engineering team.

Architecture Governance & Standards

• Define our architectural governance model for agentic SDLC from the ground up, encoding standards and principles as machine-readable context that agents consume at the start of development, so architectural alignment is built in rather than bolted on.
• Build the policy-as-code guardrails that agents cannot circumvent, to guarantee that AI-generated software aligned with our principles, quality standards and customer outcomes.
• Maintain Big Hand’s architectural standards as a clear, shared reference for how we build software.

• Experience building in cloud providers (Azure/AWS/GCP) — container orchestration (Kubernetes/AKS), managed databases, messaging, and networking.
• Experience building event-driven architectures — message brokers, event streaming, async patterns and their trade-offs.
• Experience designing systems where data privacy and auditability are first-class architectural concerns
• Strong communication and design skills — able to translate business needs into technical architectures and explain complex trade-offs to both technical and non-technical stakeholders.

Desirable

• Experience with .NET Core / C# or Java backend codebases — web APIs, data access patterns, and service composition.
• Experience integrating AI/ML capabilities into product architectures — LLMs, Azure AI services, or similar.
• Familiarity with Domain-Driven Design, No
  
  SQL databases (e.g. Cosmos
  
  DB), stream processing, or CQRS/event sourcing patterns.
