Role Description Your client is a software company running a large, business-critical ERP system used to support core operational processes such as payroll, billing, and workforce scheduling. The organisation is in the middle of a multi-year modernisation programme, moving away from a legacy technology stack toward a modern .NET/web-based platform, while keeping the legacy system fully operational in production throughout the transition. Contract: B2B or Freelance - Strong, hands-on SQL Server expertise (design, indexing, query optimisation, operational practices). - Solid working knowledge of PostgreSQL, sufficient to assess migration feasibility and compatibility. - Proven experience optimising query and index performance in production environments. - Experience modernising or refactoring databases behind legacy applications. - Ability to define and set up database observability/monitoring (baselines, diagnostics, wait stats, deadlock detection, alerting). - A pragmatic, risk-aware approach that balances improvement effort against migration cost and business risk. Qualifications - Experience assessing and scoping SQL Server → PostgreSQL migrations (not necessarily having executed a full migration). - Experience working in environments where legacy and modern systems coexist in production during a transition. - Comfort working with Specification-Driven Development (SDD) frameworks such as OpenSpec, or similar structured requirements/traceability approaches. - Ability to produce clear, prioritised, business-readable recommendations for non-DBA stakeholders. - Work from the European Union region and a work permit are required. Requirements - Review the current SQL Server database design, indexes, queries and operational practices. - Identify performance issues, technical debt, risks and areas that are already working well. - Recommend and prioritise pragmatic improvements. - Assess the feasibility of migrating from SQL Server to PostgreSQL — identifying compatibility issues, risks, expected effort and possible migration approaches. - Define and implement robust database observability and performance monitoring, including performance baselines, query-level diagnostics, wait statistics, blocking/deadlock detection, capacity trends and actionable alerting. - Work within an AI-native engineering environment, using Specification-Driven Development (SDD) frameworks such as OpenSpec to structure requirements, implementation plans, validation and traceability. Nice to have - Prior exposure to legacy 4GL or transpiled/generated codebases. - Familiarity with .NET/Blazor application ecosystems as a consumer of the data layer. - Experience with database-heavy ERP systems (payroll, billing, scheduling domains). - Experience in AI-assisted/AI-native engineering workflows more broadly.

Role Description As a Senior Software Architect at Buckhill, you will be a hands-on technical leader who shapes the architecture of our C2MS platform and drives an AI-first engineering culture across a lean, high-performing team. You will: - Write and review agentic developed code. - Conduct reviews and own real technical decisions. - Contribute towards evolving our platform architecture. - Champion agentic AI development practices. - Work closely with the Lead Product Owner, senior developer and architect colleagues, and leadership team. - Make architectural decisions by quorum through evidence and data-driven analysis. - Contribute to commercial conversations, including RFP responses, vendor evaluations, and prospect discussions, as a credible technical voice. Qualifications - 10+ years in software development and architecture, with a track record of delivering and evolving production platforms at scale. - Demonstrably hands-on: you write code with a focus on agentic development, engage in code review, and make technical decisions. - Strong breadth across modern web platform stacks, with experience working across languages such as PHP, Python, or TypeScript. - Comfort with relational databases and message bus patterns regardless of specific framework experience. - Experience with payment processing and ecommerce platforms. - Practical experience with AI/LLM integration, such as building real features or workflows using tools such as Anthropic, OpenAI, Azure AI and OSS AI models. - Experience designing and evolving platform architecture, including working with and progressively improving monolithic codebases. - Cloud deployment experience on AWS and/or Azure, with solid understanding of scalable, secure, cloud-native infrastructure patterns. - Strong API design skills and experience with integration architecture, including third-party partner and ecosystem connectivity. - Ability to work effectively in a small, fast-moving team in addition to being pragmatic, delivery-focused, and comfortable with ambiguity. - Excellent communication skills, with the ability to engage confidently with developers, product leadership, and commercial stakeholders. Requirements - Experience with agentic AI frameworks and development tooling, such as designing workflows where AI agents contribute to coding, testing, or continuous improvement. - Background in insurance, financial services, or another regulated industry. - Experience with embedded analytics platforms (e.g., Metabase or similar). - Familiarity with SaaS or PaaS product development. - Relevant certifications such as AWS/Azure Solutions Architect or TOGAF are valued but not a differentiator as practical delivery matters more. - Active participation in the InsurTech or broader technology community, such as speaking, writing, or working groups are a plus.
