Company Description
TokenFlow is an onchain token clarity platform. A B2B product, giving protocols complete visibility of their token ecosystem, including: all holder addresses, all transactions and their types, market maker tracking and performance, DeFi positions, and much more.
We're a small, lean team with lots of experience in crypto and tokenomics. We've received funding, and we're looking for our first non-founder hire.

What You'll Do
* Design and implement scalable backend services and APIs
* Architect, deploy, and operate cloud-native systems on GCP, AWS, or Azure, optimized for performance, scalability, and reliability
* Own DevOps workflows end-to-end — CI/CD pipelines, infrastructure-as-code (Terraform/Pulumi), container orchestration, and environment management
* Build, operate, and optimize data ingestion and processing pipelines for high-volume, event-driven workloads
* Integrate and manage RPC-based data sources, designing resilient systems for rate-limited, high-throughput, and fault-tolerant data access
* Design, query, and optimize relational databases, with a strong focus on data modeling, indexing, query performance, and schema evolution
* Monitor and maintain system health — defining SLOs, setting up alerting, and diagnosing performance bottlenecks across services and databases
* Apply security best practices across services — authentication, authorization, secrets management, input validation, and safe handling of sensitive data
* Secure APIs and services against common vulnerabilities — injection, broken auth, and unauthorized access
* Enforce HTTPS and encryption for data in transit and at rest, and apply least-privilege access across services and infrastructure
* Run security checks in CI/CD pipelines, maintain audit logs for sensitive operations, and set up rate limiting to protect against abuse
* Maintain a workflow, continuously identify risks, review access controls, patch vulnerabilities, and improve defenses as systems evolve
* Integrate and secure crypto wallet flows in production — signing, transaction validation, and key management
* Collaborate across product, data, and infrastructure to ship features end-to-end
* Write clean, maintainable, well-tested, and well-documented code
Requirements
* Previous experience in fullstack, backend-focused software engineering, security engineering, or crypto/web3 development
* Strong experience building backend services and APIs
* Solid understanding of relational databases, query optimization, and schema design for performance at scale
* Experience with DevOps practices including CI/CD pipelines, infrastructure-as-code, and container orchestration (Docker, Kubernetes)
* Familiarity with cloud security fundamentals — secrets management, IAM, network policies, and secure API design
* Experience securing API routes and endpoints — proper auth middleware, route guards, role-based access control, and scoped permissions
* Understanding of how to handle sensitive data — PII, tokens, credentials — including encryption at rest, masking in logs, and secure storage practices
* Experience running and debugging production systems
* Familiarity with modern frontend frameworks
* Hands-on experience running and maintaining containerized workloads in cloud environments
1.
Nice to Have
* Experience hardening production systems, database access controls, audit logging, and vulnerability scanning in CI pipelines
* Familiarity with the crypto industry, including core blockchain concepts and onchain data
* Experience with data-focused platforms (e.g. Dune Analytics, The Graph) and production-grade RPC node integration and monitoring
