Job description

Millions of people want to grow their money but don't know where to start. More than 90% of adults don’t access traditional financial advice. That's the gap Plum was built to close.

We're building the proactive money platform that makes it easy for people to smartly and sustainably grow their money. Whether you're stashing the cash for tea and toast in your first home or catching some rays during retirement, we've got your back.

Since 2016, millions of people across 10 European markets have set aside more than £10 billion with Plum. But what we're most excited about is what comes next and the opportunity for our people to help shape it.

We're now going after something even bigger: the £2 trillion+ advised market in the UK and beyond, currently locked behind high fees and complexity. By combining AI-driven financial guidance with the products people actually need, we're building a solution for everyone, not just the wealthy few.

At Plum, you'll be part of a team that's ambitious, curious and driven. We move fast, learn from what doesn't work, challenge the status quo and, most importantly, build something that makes people's lives better. We believe great ideas can come from anywhere, and that the best work happens when people feel trusted to take ownership, collaborate openly and bring their whole selves to work.

Join nearly 300 Plumsters and be part of a team shaping the future of money

The Role

At Plum, we’re looking for engineers who care deeply about technology, customer impact, and building things that scale.

We’re looking for a Staff Engineer to join our Savings group, the team behind the technology that helps millions of customers save effortlessly. From automated savings and savings goals to the financial infrastructure powering these experiences, the team tackles some of Plum’s most important and technically interesting challenges.

You’ll help shape the technical direction of Savings, connecting complex backend systems, financial infrastructure, and mobile experiences to create a platform that’s reliable, scalable, and built for rapid innovation

What You Will Do

• Architect and design modular, scalable, and observable systems that support high-volume experimentation and user engagement flows spanning from the mobile client to backend services
• Drive the Cross-Platform Strategic Vision and roadmap, ensuring our architecture supports high-volume experimentation, rapid iteration and future business needs
• Promote Continuous Improvement by driving architectural standards, engineering best practices, and operational excellence across multiple teams.
• Provide guidance to and mentor Senior Engineers and other team members, fostering a culture of technical excellence and career growth.
• Identify root causes of systemic issues and architectural bottlenecks, determining short-term mitigations and long-term strategic resolutions.
• Work and intervene on the whole life cycle of the software, from high-level system design to deployment and post-release monitoring.
• Partner closely with Product Managers and Data Scientists to design technical solutions that unlock new growth opportunities and optimize user funnels.

What We Look For

• Proven track record of technical leadership, experience designing and architecting systems at scale
• High level of pragmatism; you understand when to build for scale and when to optimise for speed of learning.
• Positive and solution-oriented mindset
• Strong planning and prioritisation skills, with the ability to translate high-level business goals into actionable technical strategies across the stack.
• Ability to share product insight with stakeholders, challenge product decisions with data, and act as a bridge between Engineering, Product, and Data Science.
• Demonstrated capacity to clearly and concisely communicate about complex technical, architectural, and/or organisational challenges to both technical and non-technical executives.
• Experience in working within a cross-functional team and collaborative environment; ability to facilitate technical decision-making and resolve conflicts across teams.
• Self-motivated and self-managing, with excellent organisational skills and a focus on high-leverage work.
• Comfortable working with both strongly and dynamically typed languages. We value your ability to architect
