Node js Developer at LXS Consulting, London, £400 per day

Node.JS Developer

Hybrid: 1-2 days in London/Reading

LXS are a global team, with talent ranging from business analysts to developers and architects, all experienced in the Altnet and Telecoms sectors.

What are we looking for?

Technical Requirements:

· Deep, hands-on experience with Node.js, especially asynchronous programming, non-blocking I/O, and a modern Node.js framework (preferably Fastify (Typescript), but Express, Koa, or Hapi is fine)

· Track record of designing and shipping microservices in production, ideally using GCP, but AWS/Azure also relevant.

· Strong grasp of API standards (REST, GraphQL, OpenAPI, Swagger, YAML).

· Proven competence with containerisation (Docker, Kubernetes) and cloud-native deployment.

· Working familiarity with DevOps tooling - CI/CD (GitHub, GitLab), IaC (Terraform, Ansible), monitoring (Splunk, StackDriver, Datadog, Grafana).

· Good security hygiene: implementing OAuth 2.0, OIDC, CORS, CSRF, etc.

· Solid experience with both SQL and NoSQL databases (e.g., PostgreSQL, MySQL, MongoDB, Redis).

· Unit and functional testing using modern test frameworks (Cypress, Mocha, Jest, etc).

Behavioural/Soft Skills:

· Able to mentor and support junior engineers with a pragmatic approach to knowledge sharing.

· Communicates clearly with both technical and non-technical stakeholders; can explain architecture decisions.

· Proactive in root cause analysis and systems troubleshooting.

· Likely a senior or lead backend engineer (or mid-weight pushing for senior), with 5+ years of real-world Node.js and cloud microservices delivery, either in digital, telecom, SaaS, or high-transaction sectors.

· “Cloud native” mindset - meaning is comfortable in containerised, automated environments and fast to pick up new DevOps tools.

· Equally happy building new services or optimising/maintaining existing ones.

· Combines both architecture/design and hands-on delivery, not “just a coder” or “just a theorist”.

· Thrives in complex environments - sees ambiguity and fast-paced change as a challenge, not a threat.

· Anyone without hands-on Node.js experience in production, lacking exposure to cloud/container environments, or uncomfortable owning the delivery end-to-end will very likely struggle.
