The industry is going through an unprecedented transformation, and we’re at the forefront. We’re proud to come to work every day knowing that what we do has a direct impact on people’s lives, with our core values guiding us every step of the way. Join us to invest in yourself, your career, and the financial world.
The role:
We’re looking for a Senior Full Stack Engineer to join our engineering team that builds state-of-the-art internal applications for front and back-office customer support agents.
As a Senior Engineer, you will be at the forefront of building mission-critical internal tools that power the day-to-day operations of our customer support organization. Our team is responsible for designing and delivering web applications that are intuitive, reliable, and deeply integrated into the operational workflows of our front and back office agents.
In this role, you will lead the development of new features and systems end-to-end, collaborating closely with product managers, designers, and peer engineers to identify problems, propose solutions, and deliver high-quality software. You’ll be deeply involved in both frontend and backend work — building responsive user interfaces in React and architecting resilient backend services with Spring Boot and Kotlin.
We are looking for someone who can take ownership of complex technical problems, design scalable systems, and mentor other engineers while continuously pushing for engineering excellence. You will help shape how our tools are built and evolve, directly influencing the efficiency and experience of hundreds of internal users across multiple lines of business.
This is a high-impact role that combines product thinking, system design, and hands-on engineering. If you thrive in an environment where your work enables others to succeed — and you enjoy building well-crafted software that solves real operational challenges — we’d love to hear from you.
What you’ll do:
- Lead the development and testing of system components/services, code and design reviews
- Participate in shaping the technical architecture of the product
- Help translate product requirements into user stories and technical solutions
- Deliver highly available and scalable services in a production environment
- Collaborate cross-functionally with product managers, designers, and other engineers to deliver high-impact features
- Own major components of the agent platform — from architecture to implementation and rollout
- Champion code quality through well-structured code, code reviews, and automated tests
- Drive engineering best practices, performance optimizations, and continuous improvements
- Mentor junior engineers and contribute to a culture of growth and innovation
What you’ll need:
- 5+ years of professional software development experience, with strong experience in full stack development
- Proficiency with React (or similar frontend frameworks like Vue/Angular) and modern JavaScript/TypeScript practices
- Deep understanding of backend development with Spring Boot and Kotlin (or willingness to ramp up quickly on Kotlin)
- Experience working with RESTful APIs, event-driven architecture, and microservices
- Solid understanding of database systems (SQL and/or NoSQL) and backend scaling patterns
- Ability to lead complex projects end-to-end and collaborate with stakeholders across product and operations
- Strong communication skills and a pragmatic approach to solving business problems
- Strong sense of responsibility; driving a project from inception to completion
- Affinity for solving problems and shipping impactful features, not polishing perfect code or architecture
- Experience working in a collaborative coding environment, refining designs together, working through code reviews and managing pull requests
