Job Description

Full Stack Developer, hybrid role for a London based company paying up to £90k with Node, Typescript, React, AWS skills. This founder‑led, family‑owned technology business, based in central London, uses modern software to power nationwide operations. With a collaborative culture, a calm delivery mindset, and a genuine focus on long‑term stability over short‑term pressure, we’ve built a platform that is both reliable and constantly evolving. £80‑90K + benefits.

The Developer/CTO is retiring and will support a structured handover over several months. You’ll have access to the long‑standing remote software architect for guidance, but day‑to‑day it will be your platform to shape and own. If you enjoy autonomy, breadth, and the chance to influence the future of a well‑established product, this is a standout opportunity.

Benefits to You

• Full ownership of our technology stack and platform direction
• Work closely with two highly technical founders (ex‑derivatives traders)
• Build, shape, and maintain systems used nationwide
• Join a stable, close‑knit team that values smart thinking, curiosity, and calm execution

What We're Looking For

A balanced full‑stack technologist with deep hands‑on coding ability across TypeScript, JavaScript, Node.js, and React. You’ll be equally comfortable architecting new features, writing clean code, integrating with AWS services, and supporting production systems. AWS Cloud and SQL experience are essential; Unix scripting and data transformation skills are a bonus.

Core Requirements

General

• Enthusiastic, positive mindset with strong intellectual curiosity
• Genuine passion for programming and problem‑solving
• Able to prioritise and manage workload independently
• Collaborative, but comfortable taking ownership
• Adaptable and eager to learn new tools and skills
• Degree‑level education preferred

Core Competencies (Must‑Have)

Full‑Stack Development

• Build and maintain REST APIs, web applications, and reusable React components/services
• Strong Node.js + TypeScript skills, including modern ES6+ patterns
• Ability to assess, select, and integrate NPM packages with a focus on security and maintainability

Cloud (AWS)

• S3 – correct use of metadata/headers (e.g., Content‑Disposition)
• DynamoDB – data modelling and access‑pattern design (appropriate pk/sk selection)
• AWS SDK v3 – List/Get/Put/Copy/Delete operations across S3 and DynamoDB

Data & Security

• PostgreSQL – querying, manipulation, and familiarity with PostgREST concepts
• Working knowledge of HTTP verbs, patterns, and JWT‑based authentication
• Ability to generate and use SSH keys; strong awareness of credential and permission security

Helpful Experience (Nice to Have)

Frontend & Integrations

• Highcharts (JSON‑driven), Axios for API clients
• SFTP workflows (e.g., FileZilla)

AWS & DevOps

• API Gateway, Lambda, IAM; experience with serverless deployment
• Provisioning Ubuntu EC2 instances; configuring web servers/databases
• Managing security groups/ACLs; basic observability and monitoring

Tooling & Testing

• Webpack 5, Jest/Mocha, or similar testing tools
• Understanding Unix permissions; basic Bash/PowerShell scripting

MongoDB

• Querying via IntelliShell; using archive/transfer tools
