About this role

The Role Tolken is a deeply technical team looking for a builder who craves complexity and ownership. You will work across the stack, from the core ledger to the user interface, ensuring systems are not just functional, but hyper-scalable, secure, and auditable. You will be hands-on in design, implementation, and deployment, collaborating closely with the founders to ship production-grade features in a high-velocity environment. Key Responsibilities

Design, build, and maintain end-to-end features across backend (ledger, routing services) and frontend (React-based UI).
Implement and evolve production-grade APIs, data models, and integrations for a high-throughput financial system.
Own the full lifecycle of features: design, implementation, testing, deployment, and ongoing reliability in production.
Collaborate closely with the VP of Engineering, founders, and other engineers to translate product requirements into technical designs and delivery plans.
Improve performance, scalability, and observability of the platform through profiling, tuning, and better monitoring.
Contribute to engineering standards, code reviews, and technical decision-making in a fast-paced startup environment Stack & Core Requirements
5+ years building high-throughput, distributed backend systems; you understand the difference between “working” and “production-grade.”
Strong backend experience in Python (FastAPI preferred), Go, or Java.
Strong command of modern frontend stacks (e.g., React) and ability to build complex, data-dense interfaces.
Deep understanding of modern database design; depth in Postgres and Redis is a strong plus.
Hands-on experience with cloud-native environments (GCP preferred), containers, and Kubernetes. System Architecture & Practices
Mastery of distributed systems concepts: microservices, idempotency, retry/backoff strategies, and eventual consistency.
Experience with event-driven architectures and high-volume queues (e.g., Kafka, Redis Streams) and caching layers.
