VB Portal Senior Dev FULL TIME & PERMANENT

Role Overview

We are looking for an experienced Full Stack Software Engineer to design, build, and maintain modern, scalable, and resilient digital applications using the MERN stack (MongoDB, Express, React, Node.js) or closely related technologies.
The role is suited to a mid to senior-level developer who is comfortable working across the full stack and within complex technology environments, particularly those commonly found in the telecommunications industry. While Telecommunications B2B experience (e.g. CPQ, quoting, product configuration) is valuable, it is not mandatory, and the engineer will be supported by Telecoms B2B domain specialists.
This role combines strong hands-on engineering with collaboration, problem-solving, and delivery discipline in an Agile environment.

Key Responsibilities

Full Stack Engineering

Design, develop, test, and maintain end-to-end web applications, spanning modern front-end frameworks and backend services.
Build responsive, high-quality React-based user interfaces, with attention to usability, maintainability, and performance.
Develop robust server-side services and APIs using Node.js and related frameworks.
Implement secure, well-structured data access layers using NoSQL (e.g. MongoDB) and/or relational databases.
Apply clean architecture principles, modular design, and strong engineering standards.

Microservices, Resilience & Performance

Contribute to the design and implementation of microservices-based architectures.
Engineer solutions with resilience, fault tolerance, and fail-safe behaviour in mind (timeouts, retries, graceful degradation).
Identify, analyse, and remediate performance bottlenecks across frontend, backend, and data layers.
Ensure solutions meet key non‑functional requirements (availability, scalability, reliability, latency).

DevOps & Engineering Practices

Work within established CI/CD pipelines to enable consistent, automated build, test, and deployment processes.
Collaborate with DevOps and platform teams on containerised and cloud-based deployments.
Support operational readiness through logging, monitoring, and incident analysis.
Promote engineering best practices including code reviews, automated testing, and continuous improvement.

Collaboration & Delivery

Work effectively in Agile teams, collaborating with product owners, architects, QA, UX designers, and operations.
Translate business and technical requirements into practical, implementable solutions.
Provide accurate estimates, communicate progress clearly, and proactively manage risks and dependencies.
Mentor less experienced engineers where appropriate and contribute to a strong engineering culture.

Required Skills & Experience

Technical (Essential)

Solid experience as a Full Stack Developer, working on production systems.
Strong proficiency in JavaScript / TypeScript.
Hands-on experience with React and modern frontend development patterns.
Backend development experience using Node.js (and frameworks such as Express or similar).
Experience working with NoSQL databases (e.g. MongoDB); SQL experience is beneficial.
Practical experience designing and consuming REST APIs.
Exposure to microservices architectures, distributed systems, or modular backend designs.
Familiarity with CI/CD pipelines, Git-based version control, and automated testing.
Comfortable working in Linux/Unix environments.

Industry Experience

Experience working in the telecommunications industry (consumer or enterprise domains).
Understanding of large-scale, integration-heavy environments typical in telco landscapes.

Preferred / Advantageous Experience (Not Mandatory)

Telecommunications B2B experience (e.g. CPQ, quoting, product catalogues, order management).
Cloud platforms (AWS, Azure, or GCP).
Containerisation and orchestration (Docker, Kubernetes).
Observability tooling for monitoring, logging, and performance analysis.
Product-focused delivery experience and collaboration with UX / product design teams.

What We’re Looking For

A strong hands-on engineer who enjoys building real systems end-to-end.
Someone who values quality, performance, and resilience, not just feature delivery.
A collaborative team player who communicates clearly and works well in complex environments.
An engineer comfortable operating with domain support from specialists, without needing to be a CPQ or B2B expert themselves.

Qualifications

Degree in Computer Science, Engineering, or a related discipline or equivalent practical experience.
