Full job description

Murphy AI deploys voice AI agents that help banks collect debt. We’ve built a fully-fledged platform designed to optimize recovery rates while maintaining respectful and personalized communication. Our advanced automation streamlines the process of collecting overdue invoices for banks and other industries, providing a seamless and effective solution.

Our AI-powered agents adapt instantly, engaging with debtors across channels like voice, messengers, email and sms to maximize results while preserving trust. By combining advanced artificial intelligence with powerful automation, we’re setting a new standard for how businesses recover payments.

As a fast-growing startup that has already made an impact within less than a year in the market, we are building a talented team to scale our operations and drive our vision forward

About the Role

As a Software Engineer, your mission is to own real problems end-to-end, from design to production, on a platform designed to scale natively: an event-driven architecture where AI agents negotiate with real people on behalf of banks, under real SLAs and bank-grade security.

We're AI-native in how we build, not just what we sell: LLM evals score 100% of our conversations, adversarial agents attack every change before it reaches production, and our CI/CD runs its own AI agents : reviewing code, catching regressions, and fixing vulnerabilities.

You'll build alongside a team of excellent engineers who hold a high bar, shipping to production in your first week and owning more as the company grows.

You will have end-to-end ownership over what you build.

Responsibilities

Own problems : understand the real need, design the solution, ship it, run it in production, and iterate on real usage.
Build and evolve the products our customers live in - where they configure their strategy, follow their portfolio, and understand every AI conversation.
Extend the machinery that lets Murphy scale the business in our sleep: self-serve onboarding, integrations with our customers' systems (CRM, ERP, core banking), and the data flows that feed our AI agents - where every conversation makes the next one smarter.
Contribute to internal tools, AI skills and automations that make every team at Murphy faster. Engineers shape how the company works, not just what it ships.

Requirements

4+ years of proven experience building and scaling production software — fullstack, or strong backend/frontend engineers who want to go fullstack.
Strong proficiency in TypeScript across the stack: Node.js on the backend, React (or a similar modern framework) on the frontend.
Demonstrated ability to design, run, and debug real production systems — failure modes, latency, and cost included.
Strong ownership: you take a problem, not a spec, and come back with it solved.
You use AI tools aggressively but critically: let them write the code, you own the thinking — and when you merge it, you own it.
Excellent communication and collaboration skills, able to work effectively in cross-functional teams.

Bonus points

Experience with cloud platforms (AWS, GCP, Azure)
Knowledge of CI/CD pipelines and automated testing
Previous experience in AI/ML projects or startup environments.

What we offer

Compensation: £50k–75k for Mid Level // £75k–100k+ for Senior Level

Stock options: Because we all build Murphy together – you'll own a piece of what we’re creating.

Impact & Growth: Early role in a fast-growing startup, with mentorship and opportunities to take on more responsibility as you grow.

Learning: Continuous development through mentorship, trainings, and exposure to real-world AI projects.

Pension Plan: 5% contribution to Aviva Pension Plan

Hybrid & Flexible: Our default setup is hybrid – 3 days a week at the office, surrounded by a thriving tech scene, and 2 days of remote work. But if there’s one thing that defines us, it’s flexibility: we trust you to organize your time and space in the way that helps you do your best work.

Our Process

1️⃣ First Interview – Getting to Know You

A conversation with a future teammate who’s excited to find a new colleague. We’ll talk about your story, what drives you, and what you’re looking for next—no trick questions, just a genuine exchange.

2️⃣ Second Interview – Deep Dive

You’ll meet the Hiring Manager and potentially another team member. This is a more technical discussion where we explore your skills in detail, walk through real scenarios, and answer any questions you might have about the role.

3️⃣ Tech Assessment or Business Case

A practical exercise to see how you approach challenges similar to those you’d tackle at Murphy. You’ll have time to reflect and showcase your thinking—no rush, no surprises.

4️⃣ Call with the Founders

Our founders meet every team member and it’s a great opportunity for you to learn about the company and its direction.

To learn more about how we hire and what to expect at every step, feel free to explore our Hiring Guide!

We are committed to building a diverse, inclusive, and equitable workplace where everyone, regardless of background, identity, or experience, feels valued and empowered to thrive. We believe that different perspectives drive innovation and success, and we actively foster an environment where all voices are heard and respected.
