Junior Web Developer

Who We Are
At Secco Squared, we’re a fast-moving performance marketing company helping brands grow through digital advertising. We use email, media buying, and first-party data strategies to drive real, measurable results.
We’re a small, nimble team that values action, initiative, and smart thinking.

About the role

We’re looking for a Junior Web Developer to work alongside us on a growing portfolio of Next.js projects. You’ll be hands-on with real production code from day one — building features, integrating APIs, and shipping things that actual users touch. This is a great fit for someone early in their career who has solid fundamentals and wants to grow quickly in a small, fast-moving setup.

You’ll mostly be supporting ongoing projects: implementing new features, wiring up backends, fixing bugs, and helping turn ideas into working software. You won’t be left to figure everything out on your own — but you should be comfortable owning tasks and asking good questions.

What you’ll do

Build and maintain features in Next.js / React applications
Integrate with Supabase (auth, database, storage, edge functions) and design clean data flows
Work with REST and third-party APIs — reading docs, handling auth, debugging requests, implementing integrations end-to-end
Write code that’s readable and easy for the next person to pick up
Collaborate on technical decisions — sometimes you’ll get a clear spec, sometimes we’ll figure it out together

Requirements

Working knowledge of Next.js and React — you’ve built projects with them, understand the App Router, server vs. client components, and basic data-fetching patterns
Comfortable with TypeScript and modern JavaScript
Tailwind CSS and experience translating designs into clean UI
Experience with Supabase (or a similar Postgres-based stack) — auth, RLS policies, queries, and storage
Solid understanding of how APIs work: HTTP methods, status codes, authentication (API keys, OAuth, JWTs), pagination, and error handling
Git fundamentals — clear commit messages and PRs
Good written communication, async-friendly

Nice to have

Python experience — we use Python a lot on the data and automation side, so it’ll come up
Exposure to deployment workflows (Vercel, Railway, or similar)
Any experience with MCP, AI tooling, or workflow automation platforms
Experience with performance marketing data, analytics tools, or reporting pipelines
