That’s all down to our passionate team of 200+ Plumsters, who work around Europe to help us achieve our mission. And now we’re looking for more brilliant people to join us on our journey.

The Role

At Plum we’re looking for engineers who are passionate about both technology and bringing the best product to our customers. To achieve this mission, we need technical leaders who can look beyond individual features to drive the technical strategy that accelerates our user growth and engagement.

We are looking for a Staff Engineer for our First & Last Mile group, the team responsible for driving the core user lifecycle, including user Onboarding, Offboarding, Authentication, Engagement, and Subscriptions. We need a technical leader who understands how to bridge the gap between complex backend services, mobile client architecture, and business impact. You will not only have a strong technical background but also the ability to define technical roadmaps, elevate the engineering culture, and architect systems that enable rapid experimentation across our entire stack.

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 optimise user funnels.

What We Look For

• Proven track record of technical leadership, preferably in a mobile-heavy or full-stack capacity
• Experience designing and architecting systems at scale
• Deep experience with A/B testing frameworks, experimentation platforms, or data-intensive growth loops.
• 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
