Job description
On behalf of our client, a payment-provider orchestration company, we are looking for a Junior Full-Stack Engineer to join their growing engineering team.
About Our Client
Our client is building a payment-provider orchestration platform that helps businesses integrate, manage, and switch between payment services without rebuilding their systems each time.
They value thoughtful engineering, simple solutions, open communication, and products that work reliably. Their engineers contribute across the whole product lifecycle — shaping requirements, weighing technical trade-offs, building, testing, and deploying.
If you want to grow across the full stack, take real ownership, and help shape a growing fintech product, we would like to hear from you.
The Role
We are looking for a Junior Full-Stack Engineer to help build web applications across the frontend, API, and data layers.
You will work mainly in TypeScript, React, Next.js, Node.js, and PostgreSQL, alongside product, design, and engineering. You will start with clearly scoped tasks and take on larger features as your confidence grows, with regular guidance and code review from experienced engineers.
You do not need experience with every technology in the stack. They hire for fundamentals, curiosity, and how quickly you learn.
Their Stack
TypeScript · React · Next.js · Tailwind CSS · Node.js · Express · PostgreSQL · Drizzle ORM · Zod · AWS · Git
AI tooling: Claude Code CLI · Codex CLI · AI-assisted code review
How They Work with AI
AI-assisted development is part of how the team builds, not an optional extra. Their engineers use agentic coding tools such as Claude Code CLI and Codex CLI every day — to write and refactor code, explore unfamiliar parts of the codebase, generate tests, and support code review.
They also build AI-driven features into the product itself, so you will work with AI frameworks and APIs as part of normal engineering work.
You are expected to use these tools thoughtfully. You should be able to explain any code you submit, review AI-generated output critically rather than accepting it, and understand where these tools help and where they do not. You do not need prior experience with them — but you do need to be genuinely open to working this way, and willing to learn quickly.
What You Will Do
Build and improve product features in TypeScript, React, Next.js, and Node.js
Create responsive, accessible user interfaces
Help build and integrate REST APIs with Express
Model and query relational data with PostgreSQL and Drizzle ORM
Validate data at application boundaries using Zod
Write unit and integration tests, with support from the team
Investigate bugs and ship fixes that hold up over time
Use AI coding tools such as Claude Code CLI and Codex CLI in your daily workflow, and review their output critically
Work with AI frameworks and APIs as the team builds AI-driven capabilities into the product
Take part in code reviews, technical discussions, and deployments
Take on more ownership as your skills and product knowledge grow
What You Will Bring
Around 1–2 years of professional experience, including internships or equivalent practical work
Solid JavaScript or TypeScript fundamentals
Working knowledge of React or another modern frontend framework
A basic understanding of Node.js, REST APIs, and HTTP
Some exposure to PostgreSQL or another relational database
Evidence that you can build software — through professional work, internships, university, bootcamps, freelance projects, or personal projects
Familiarity with Git-based workflows and automated testing
Genuine openness to AI-assisted development — working daily with agentic coding tools such as Claude Code CLI or Codex CLI, and with AI frameworks in the product
The judgement to review AI-generated code properly and explain anything you submit
Strong problem-solving skills and attention to detail
Comfort asking questions, receiving feedback, and acting on it
Clear written and spoken English
What's on Offer
Structured support — regular guidance, constructive feedback, and thorough code reviews
Growing ownership — start with well-defined work and progress to owning complete features
Private health insurance — support for your health and wellbeing
Learning budget — for courses and certifications
Modern tooling — paid access to leading AI coding tools and everything else you need to do your best work
Real product experience — features that solve meaningful problems for real users
Technical breadth — frontend, backend, databases, testing, and cloud infrastructure
A collaborative team — open communication, honest feedback, and room for different perspectives
