- Use customer feedback, analytics, and direct user insights to inform technical decisions, prioritise improvements, and validate that shipped features deliver measurable value.
- Design and implement complex data flows, API integrations, and background processing systems that handle high-volume operations reliably while maintaining system performance and data integrity.
- Partner with product, design, and customers to shape solutions early, translating business requirements into technical architecture while surfacing risks and opportunities that impact customer outcomes.
What you’ll bring
Essential
- JavaScript / TypeScript – core programming languages
- Node.js – primary backend framework
- API design and implementation
- Git – version control and collaborative workflows
- Testing strategies (unit, integration, end-to-end)
- Experience with monitoring, logging, and observability tools
- Familiarity with modern AI tools and a habit of staying up to date with how they can improve engineering workflows
Highly desirable
- AWS infrastructure and services
- MongoDB or other NoSQL database
- SQL databases and query optimisation
- CI/CD pipelines and DevOps practices
Nice to have
- AdonisJS, NestJS or similar MVC frameworks
- Distributed systems experience
- Message queues and background job processing
- Caching strategies and performance optimisation
- Security best-practices implementation
- Experience in a growth-stage startup or B2B SaaS
