Senior Product Engineer

Our growth rate puts us in the top quartile of private B2B SaaS companies at our stage, and we’ve achieved it with low churn and without burning VC cash to get there. We’re small, profitable, and growing fast. We’re also an AI‑first company. Every process we build assumes the person running it will be using the best tools available today and whatever comes next. If you want a role where you’ll use modern AI tooling every day rather than watch it replace you, this is it.

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
• 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
• 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
