About the Opportunity

Join a growing technology company building software that helps financial institutions and global businesses detect financial crime, manage risk, and make faster, better-informed decisions. This is a hands-on product engineering role for someone who can design strong systems, build reliable software, and take ownership without waiting for step-by-step direction.

You will work primarily on backend systems while contributing to frontend development when needed. The team operates with the pace and accountability of a smaller company, so success requires sound judgment, curiosity, and a willingness to identify where you can help most.

What You Will Do



  • Design, build, test, and maintain product features across backend services and selected frontend components.





  • Own technical work from problem definition and system design through implementation, release, and ongoing improvement.





  • Make strong architectural and system-design decisions involving scalability, reliability, maintainability, security, and performance.





  • Modernize existing applications and improve code quality without disrupting critical business workflows.





  • Partner closely with product managers and other engineers to turn business needs into practical technical solutions.





  • Investigate problems independently, propose solutions, and move work forward with limited oversight.





  • Review code, share technical knowledge, and help raise engineering standards across a small, collaborative team.





  • Identify useful work, risks, and improvement opportunities instead of waiting to be assigned every next step.



What We Are Looking For



  • Proven senior-level software engineering experience with deep strength in backend product development.





  • Very strong system-design skills and the ability to explain technical decisions, tradeoffs, and long-term consequences clearly.





  • Experience building and maintaining production software used by real customers.





  • Experience contributing to frontend applications, with comfort working across the stack when the product requires it.





  • Excellent spoken and written English, including the ability to communicate complex technical ideas clearly.





  • A personable, collaborative working style and the confidence to engage directly with technical and non-technical teammates.





  • High ownership and initiative: you find the best way to help, solve ambiguous problems, and follow through without constant direction.



Strongly Preferred



  • Experience working in a startup, scale-up, or other small-company environment where engineers take broad ownership.





  • Experience in fintech, financial services, risk, compliance, payments, or another regulated financial domain.





  • A record of improving existing systems while continuing to deliver new customer-facing functionality.



Role Scope

This is a product software engineering position. It is not a data engineering, data science, DevOps, site reliability, or infrastructure role. Candidates should be strongest in application development, backend systems, and system design.

What Success Looks Like



  • You quickly understand the product, users, and technical landscape.





  • You make sound system-design decisions and deliver reliable, maintainable software.





  • You communicate early when priorities, risks, or tradeoffs are unclear.





  • You consistently look for the highest-value way to contribute and help the team move forward.
