More about our mission and what we offer.
We're looking for an experienced Senior Backend Engineer to join our Rules Platform Team.
This team is responsible for Wise's critical rules engine, which includes the tool used to manage our risk assessment rules.
As a senior member of this team, you will be a key technical voice. You will lead and contribute to impactful, cross-functional engineering initiatives, drive critical system architecture and technical design decisions, and ensure high service standards by monitoring and optimizing the system performance. You will also actively participate in strategic planning, shaping the product roadmap and defining the future evolution of the platform.
What will you be working on?
You will join the team at an exciting time of growth, as we scale our core risk assessment capabilities. The core challenge is to evolve our rules engine and internal libraries to support growing demand and complexity from teams across Wise.
Drive Complex Initiatives: Lead the design and implementation of complex backend initiatives that form the foundation of our risk platform.
Own Core Components: Take ownership of maintaining and evolving the internal libraries and shared components consumed by multiple teams, ensuring they are robust, scalable, and well-documented.
Design for Scale: Contribute directly to the architectural design and scaling of our risk assessment services, ensuring they meet high standards for performance, reliability, and data consistency.
Collaborate for Impact: Work as a key technical partner with multiple stakeholders—including Product, FinCrime, and other engineering teams—to deliver robust, cross-functional solutions.
You'll work in a collaborative environment where you can influence key technical decisions, mentor other engineers, and help define how we scale our platform. It's a strong opportunity to grow into greater technical leadership and work on complex, meaningful problems at scale.
What do you need?
Strong proficiency in JVM-based languages (e.g., Java, Kotlin).
Proven experience maintaining internal libraries or shared components consumed by multiple teams.
Experience working with Kafka and SQL databases in complex backend systems where reliability and data consistency are critical.
Strong mentorship skills with a passion for supporting and leveling up junior engineers.
The ability to prioritize, evaluate tradeoffs, and make informed technical decisions, and comfort in leading technical discussions and architecture proposals.
Proactivity and a collaborative mindset, with experience working closely with Product Managers on decision-making.
Experience building or working with custom DSLs (Domain-Specific Languages).
Background in the FinCrime domain, risk decisioning teams, or regulatory environments where auditability and traceability are important.
For everyone, everywhere. We're people building money without borders — without judgement or prejudice, too. We believe teams are strongest when they are diverse, equitable and inclusive.
We're proud to have a truly international team, and we celebrate our differences.
Inclusive teams help us live our values and make sure every Wiser feels respected, empowered to contribute towards our mission and able to progress in their careers.
