Software Engineer (AI Assistant Product)

You will be part of a multi-disciplinary product team that designs, builds and ships full stack web applications that directly support organisational operations and decision-making. A key focus of this role is the development of an internal chat assistant powered by production AI, purpose-built to augment the productivity and capabilities of staff across the organisation. You are a motivated self-starter who takes initiative, thrives in a collaborative environment, takes ownership of features end-to-end and cares deeply about the quality and reliability of code running in production.

Responsibilities :
• Design, develop and deploy scalable full stack features across the frontend and backend, from user-facing interfaces to APIs and data layers

• Write high-quality, well-tested code with unit, functional and end-to-end test coverage

• Maintain and improve the reliability of production systems – including monitoring, debugging and resolving production issues

• Participate actively in peer code reviews, enforcing best practices around code style, testability, performance and security

• Collaborate with designers and product stakeholders to co-create practical user-centric solutions

• Contribute to technical documentation and knowledge sharing within the team

• Participate in Agile Scrum ceremonies and iterative delivery cycles

Requirements:
• Background in Computer Science, Computer Engineering, Information Systems, or a related field

• Demonstrable hands-on exposure to shipping and maintaining software through industry experience, internships, open-source contributions or personal projects

• Proficiency in full stack web technologies – frontend frameworks (e.g. ReactJS) and backend frameworks (e.g. Spring Boot/Java)

• Solid understanding of RESTful API design with familiarity in microservices architecture

• Familiarity with relational and/or NoSQL databases (e.g. MongoDB)

• Experience with CI/CD pipelines, version control and build tools (e.g. Git, Maven)

• A motivated self-starter who can independently drive tasks to completion, proactively identify problems and propose solutions without needing close supervision

• Strong problem-solving skills and a growth mindset

•
Fresh graduates with demonstrable project experience – including internships, open-source contributions, or personal projects – are welcome to apply.

•
Applicants with greater experience will be considered for Senior Software Engineer positions.

Nice-to-have:
• Experience with any one of these areas: Agentic AI systems, Large Language Models (LLMs), and the LangChain toolkit – including building and maintaining LLM-powered workflows or agents in production

• Experience with container orchestration (Kubernetes) and object storage (e.g. MinIO)

• Familiarity with search technologies such as ElasticSearch or Solr

• Experience with messaging systems such as Kafka or RabbitMQ

• Exposure to observability and monitoring tooling (e.g. Elastic Stack, Prometheus, Grafana)

• Familiarity with graph databases (e.g. Neo4J)

Why Join Us:
• Work on meaningful products that create real operational impact

• Ownership over features from conception through to production deployment and beyond

• A collaborative team that invests in deepening both your core stack expertise and adjacent technical interests

• Opportunities to grow into senior engineering or technical lead responsibilities
