What you'll do:
Own and maintain critical backend systems running in production
Design, implement, and evolve backend services with a focus on reliability, scalability, and maintainability
Lead investigation and resolution of complex production issues, including performance, availability, and operational challenges
Drive architectural improvements and technical modernization initiatives
Contribute to the design and implementation of new fintech products and platform capabilities
Collaborate closely with product, infrastructure, and engineering teams to deliver high-impact solutions
Review code, mentor engineers, and help establish engineering best practices
Improve testing strategies, observability, documentation, and operational processes
Participate in technical planning, system design discussions, and architectural decision-making
Identify technical debt and proactively drive improvements across the platform
What you bring:
5+ years of professional backend development experience
Strong experience building and maintaining Django applications in production
Deep understanding of relational databases, data modeling, and query optimization
Experience designing and operating distributed or service-oriented systems
Strong understanding of asynchronous processing, background jobs, and system integration patterns
Proven ability to work effectively within large existing codebases while driving meaningful improvements
Excellent debugging, troubleshooting, and problem-solving skills
Experience making architectural decisions and evaluating technical trade-offs
Strong communication skills and ability to collaborate across technical and non-technical teams
Ability to mentor engineers and contribute to a culture of technical excellence
Nice to have:
Experience in fintech, payments, banking, or other high-reliability environments
Experience with high-throughput or data-intensive systems
Familiarity with message queues, caching systems, event-driven architectures, and distributed systems
Experience with containerized and cloud-native environments
Experience with observability, monitoring, and incident response practices
Proficiency in more than one programming language
Experience leading technical initiatives or projects from design through delivery
Tech Environment:
A backend-focused environment built around modern web frameworks, relational databases, asynchronous processing, and contemporary deployment and infrastructure tooling. We value strong engineering fundamentals, system design expertise, and production experience over experience with any specific technology stack.
Why join us:
Opportunity to own and shape critical backend systems that support real-world financial products
Significant influence on technical direction, architecture, and engineering practices
Exposure to challenging scalability, reliability, and operational problems
Collaborative engineering culture focused on quality, learning, and continuous improvement
