The Role

At Plum we’re looking for engineers who are passionate about both technology and bringing the best product to our customers.

• Positive and solution-oriented mindset.
• Strong planning and prioritisation skills.
• Ability to share product insight with stakeholders and challenge product decisions with data.
• Demonstrated capacity to communicate about complex technical challenges to both technical and non-technical executives.
