Regular / Senior Backend Developer (Node.js / TypeScript)

About hubQuest

hubQuest brings together IT and analytics experts to build technology teams from scratch and strengthen existing teams for its partners. We help organisations develop solutions that support their transformation and create meaningful impact.

About the role

We’re looking for an experienced Backend Developer with strong Node.js, TypeScript and NestJS skills to join the team developing an AI Virtual Assistant for a global organisation operating across the food, beverage, fragrance, health and bioscience sectors.

The application supports people working in manufacturing sites. It initially developed as an additional interface for an existing platform used for processes such as document management and incident reporting. It is now evolving into a broader product supporting everyday factory operations and the needs of site teams and leadership.

We have a substantial roadmap of new features to build and roll out. You’ll develop the backend services, APIs and data flows behind these capabilities, while helping ensure the application is reliable, maintainable and easy to monitor and troubleshoot.

We’re open to both strong mid-level developers who can deliver independently and senior developers who bring broader technical ownership and experience.

What you’ll work on

The upcoming scope includes:

• Safety and quality workflows.

• Audits, audit results and follow-up actions.

• Dashboards presenting operational information.

• Tier meetings supporting coordination and performance reviews at different organisational levels, from shop-floor teams to leadership.

Future plans include integrations with machine-monitoring applications and AI capabilities that help people access knowledge and understand what is happening across manufacturing sites.

These are future development directions, with the immediate focus on building and delivering the product’s expanding operational capabilities.

The team and technology

The team currently includes a Product Owner, a Lead Developer, two AI Developers and a Software Developer. We’re expanding it with a UX Designer, a Frontend Developer and this Backend Developer role.

The backend uses Node.js, TypeScript and NestJS, with Microsoft SQL Server as the relational database and AWS as the cloud environment. The frontend is built with React.

You’ll work closely with the Lead Developer, frontend and AI developers, Product Owner and UX Designer to deliver complete features.

What you’ll do

• Build and extend backend services and APIs using Node.js, TypeScript and NestJS.

• Translate business requirements into backend logic, data models and maintainable technical solutions.

• Design and maintain relational database structures, write queries and investigate performance issues.

• Develop integrations with existing platforms and other services.

• Work with AWS services supporting the application.

• Set up and improve observability, including structured logging, monitoring and alerting, using tools such as Amazon CloudWatch.

• Investigate production issues and improve the application’s reliability and troubleshooting capabilities.

• Collaborate with frontend and AI developers on API contracts, integrations and feature delivery.

• Write maintainable code, participate in code reviews and contribute to appropriate automated testing.

• Take ownership of assigned features, communicate progress and raise risks or dependencies early.

• Participate in daily stand-ups and two-week sprints.

What we’re looking for

• Strong commercial experience developing backend applications with Node.js and TypeScript.

• Practical experience with NestJS and building maintainable, modular backend applications.

• The ability to deliver production features independently at a strong mid-level or senior level.

• Hands-on experience with AWS in a production environment.

• Experience setting up observability, including configuring logging, monitoring and alerting—not only using existing dashboards.

• Practical experience with logging and monitoring tools such as Amazon CloudWatch, including using them to investigate application issues.

• Experience with relational databases, including data modelling, SQL and query optimisation. Microsoft SQL Server is preferred, but experience with other relational databases is also welcome.

• Experience designing and developing APIs and integrating backend services with other systems.

• A practical approach to code quality, testing, debugging and maintainability.

• Confidence working with evolving requirements and discussing technical choices with the team.

• Strong communication skills and a collaborative approach.

• Very good spoken and written English for everyday work in an international environment.

Nice to have

• Hands-on experience with Microsoft SQL Server, if your main experience is with another relational database.

• Experience with distributed tracing and diagnosing issues across multiple services.

• Practical experience using Claude to support software development, with careful review and validation of generated code.

• Experience building internal business applications or tools supporting manufacturing, safety, quality or audit processes.

• Experience integrating applications with AI services.

What we offer

• A full-time B2B engagement.

• A fixed-term contract through 30 June 2027, with the possibility of an extension through 31 December 2027. The extension is not guaranteed.

• The opportunity to contribute to a growing product with a substantial roadmap and direct relevance to everyday manufacturing operations.

• Close collaboration with the Product Owner, UX Designer and development team.

• An international working environment and a Scrum-inspired approach, with daily stand-ups and two-week sprints.

• A friendly, non-corporate environment, flexible working arrangements, private medical care and a Multisport card.
