A growing technology-led business is rebuilding and modernising the core system including billing, invoicing, reconciliation, integrations, operational workflows, reporting, customer tooling, and internal platforms. These systems sit at the heart of the organisation and directly influence revenue, operational efficiency, customer trust, and commercial decision-making. This role is suited to someone who enjoys solving complex operational and data problems, and who takes ownership of outcomes rather than simply delivering tickets. Strong engineering judgement, systems thinking, and an appreciation for correctness are essential in an environment where mistakes can have meaningful downstream impact. AI-assisted development is already central to the engineering workflow. Tools such as Claude Code and Cursor are actively used day-to-day, and senior engineers are expected to use them confidently and pragmatically.
What Youll Be Responsible For
- Designing and evolving business-critical systems across operations, finance, integrations, and customer workflows
- Leading technical investigations into workflows, operational issues, integrations, and data discrepancies
- Partnering closely with finance, operations, support, engineering teams, and customers to solve complex business problems
- Leading technical and operational discussions with customers over calls and video meetings
- Building systems that are accurate, auditable, explainable, scalable, and maintainable
- Driving improvements in reliability, observability, documentation, and engineering standards
- Using AI-assisted development tools to accelerate delivery while maintaining engineering quality and judgement
- Helping shape technical direction, architecture, and long-term platform decisions
What Theyre Looking For
Essential
- Strong TypeScript experience across frontend and backend systems
- Deep experience with Next.js, NestJS, and modern backend architecture
- Strong SQL and data modelling skills, ideally PostgreSQL
- Experience building and maintaining business-critical systems where correctness, auditability, and operational reliability matter
- Strong understanding of distributed systems, data flows, reconciliation logic, and failure handling
- Comfortable working through operational exceptions, edge cases, and complex integrations
- Excellent communication skills with both technical and non-technical stakeholders
Highly Desirable
- Go experience, particularly in backend systems, infrastructure, concurrency-heavy workloads, or performance-sensitive services
- Experience in logistics, shipping, or supply chain operations
- Background in billing, invoicing, payments, finance, audit, or compliance-heavy environments
- Familiarity with cloud infrastructure, APIs, and data-heavy integrations
- Hands-on experience with AI tooling such as Claude Code or Cursor as part of daily engineering workflows
Salary & Benefits
- Up to £75,000 depending on experience
- 25 days holiday + bank holidays
- Flexible working arrangements - 3 days office / 2 days remote
- Opportunity to shape systems critical to business operations
