Frontend 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

• 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)

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

Professional Qualities

• 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

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 ",
