Full job description

We’re Marcode.

We build software that helps brands spot and deal with affiliate fraud. Things like paid search hijacking, browser extensions inserting themselves into journeys, and affiliates taking credit for sales they didn’t really drive.

It’s a space with a lot of nuance, and our job is to make something complex feel clear and usable for customers. We work with well-known brands and growing teams, and we’re continuing to build the product out carefully and deliberately. We’re backed by TinySeed and run the business in a grounded way. We focus on building something useful and sustainable, rather than chasing hype.

We’re a small, collaborative team. We keep things simple, communicate openly, and try not to add process unless it genuinely helps.The Role

As our Senior Product Engineer, you’ll own features end-to-end across our app, API, and data platform. You'll ship across the full stack and be responsible for what you build - from first spec to production, and everything that happens after.

Must have

Experience building features in B2B SaaS products
Full stack, T-shaped engineer whose core strength is creating delightful products
Strong instinct for what good looks like in a React app, with deep knowledge of modern patterns and best practices
Experience building UI API Data architectures
Fluency with AI coding tools (Cursor, Claude Code, Codex) as part of your daily workflow
Understand the importance of observability and being able to spot problems before customers do
Comfortable operating in a startup environment: ambiguous problems, shifting priorities, minimal process, and the autonomy (and responsibility) that comes with it
Happy to wear all the hats involved in software delivery - spec, design input, build, test, ship, support, iterate

Nice to have

Experience designing and operating offline background processing systems - job queues, scheduled workloads, event-driven pipelines
Previous experience as an early engineer at a startup, or as a technical founder

Building at Marcode

We're a small but mighty team that ships daily: no tickets, no status meetings, no layers between you and the work
"Senior" here means senior in judgement and ownership - not seniority over other engineers. You'll be doing the work, not delegating it
Our target stack is React/TypeScript Express/TypeScript Postgres + DynamoDB, running on AWS
We lean heavily on AI tools for coding, testing, and QA across both the app and our data platform - we place focus on putting the right guardrails in place so AI can produce good code
We automate as much as possible so we can focus on the things that actually matter
"You build it, you run it" is core to how we operate - you're the first responder for what you ship
This role suits someone who's energised by scope and autonomy, and frustrated by process and meetings

Interview Process:Video call with our Talent Partner Technical deep dive (walk us through something you’ve built) Final F2F with the founders
