Front End Web Developer

Position Overview

We’re seeking a pragmatic, execution-focused frontend developer who thrives on keeping products that people actually use running, improving and shipping. You will join a small technical team as the day-to-day custodian of a suite of internally built web applications in daily use across our international offices. The role begins with technical support, bug fixes, and feature implementation on these live systems, with a path to owning the suite

​

Technical Requirements

Core Frontend Skills

• Vanilla Web Technologies: Extensive experience with HTML, CSS, and vanilla JavaScript (React/Next.js not required)

• Node.js Backends: Comfortable reading, debugging, and extending Node.js/Express REST API servers

• SQL: Confident writing and debugging T-SQL against large production databases, with the care and discipline live data demands

• API Integration: Proven ability to integrate frontend applications with RESTful API endpoints and third-party APIs

• Authenticated Applications: Experience with multi-role web applications (SSO, role-based access control)

• Azure: Working knowledge of Azure App Service, deployment slots, log streaming, and Azure DevOps repos and pipelines

• Testing Expertise: Strong experience writing and maintaining unit, subsystem, and system tests for frontend applications, and the discipline to verify in staging before touching production

• LLM-Powered Development: Extensive hands-on experience using Claude and other LLM models for code generation, debugging, and code review processes

• LLM Integration In-Product: Experience shipping LLM-powered features to end users (API integration, streaming responses, prompt payloads, graceful error handling)

Development Approach

• Rapid Iteration: Demonstrated ability to maintain extremely fast project/feature shipping cadence

• Show, Don't Tell: Strong adherence to "iterate by showing" methodology rather than endless planning discussions

• Production Instincts: Respect for live systems, reproduce first, fix at the root, verify in staging, deploy cleanly, watch the logs

• Design Instincts: Solid intuition for web page layouts, interaction design, and user journey mapping (tools agnostic - Figma, PowerPoint, whiteboard sketches all welcome)

Preferred Additional Skills

• Internationalisation: Experience building multi-language user interfaces and translation-friendly frontends

• Configuration-Driven UI: Experience building dynamic, configuration-driven interfaces such as form builders or template engines

• Voice & Speech Interfaces: Experience with speech-to-text, transcription API integration, or voice-driven UI

• Mobile Development: Experience building iOS/Android applications, particularly with Flutter

• Browser Extensions: Ability to develop Edge/Chrome extensions

• Microsoft Ecosystem: Experience building applications for Microsoft native applications (Outlook, etc.) that leverage Microsoft Graph API

​

Professional Qualities

Communication & Leadership

• Exceptional written and verbal communication skills - most issues arrive as plain-language reports from non-technical colleagues

• Ability to engage effectively with non-technical stakeholders, translate a vague complaint into a precise defect, and close the loop when it is fixed

• Capable of independently driving fixes and features from report or concept through to verified resolution in production

• Strong system architecture instincts with ability to quickly converge on project requirements

Mindset & Approach

· Battle-Hardened: Experienced with failure, learning, and perseverance through multiple project cycles

· Completion-Focused: Understanding that project success is measured by user adoption, not feature completion

· Anti-Shiny Object: Ability to resist temptation of new technologies when focus should be on grinding through current priorities

· Stakeholder Engagement: Strong skills in scoping functional and technical implementation, prioritization, and planning

​

Personal Characteristics

· Personable & Collaborative: Solid people skills, approachable, no ego or academic elitism

· Mission-Oriented: Willing to upskill, pivot, or abandon work as business needs require

· Agency Embodied: Self-motivated, proactive, with internalized drive to map goals to actions

· Pragmatic Executor: Focused on results

​

Work Environment

You'll be working with 1-2 technical colleagues and hundreds of non-technical team members. Success in this role requires someone who can bridge technical and business domains while maintaining focus on practical outcomes over technical perfectionism.

​

What They Value

· Shipped products that people use

· Speed of execution over architectural purity

· Business impact over technical achievement

· Collaborative problem-solving over individual heroics

· Practical solutions over elegant code

This role is ideal for a developer who has learned that the best code is code that solves real problems for real users, and who finds satisfaction in seeing their work drive actual business outcomes.
