Company DescriptionTokenFlow 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.https://tokenflow.tech/What You'll DoDesign and implement scalable backend services and APIsArchitect, deploy, and operate cloud-native systems on GCP, AWS, or Azure, optimized for performance, scalability, and reliabilityOwn DevOps workflows end-to-end — CI/CD pipelines, infrastructure-as-code (Terraform/Pulumi), container orchestration, and environment managementBuild, operate, and optimize data ingestion and processing pipelines for high-volume, event-driven workloadsIntegrate and manage RPC-based data sources, designing resilient systems for rate-limited, high-throughput, and fault-tolerant data accessDesign, query, and optimize relational databases, with a strong focus on data modeling, indexing, query performance, and schema evolutionMonitor and maintain system health — defining SLOs, setting up alerting, and diagnosing performance bottlenecks across services and databasesApply security best practices across services — authentication, authorization, secrets management, input validation, and safe handling of sensitive dataSecure APIs and services against common vulnerabilities — injection, broken auth, and unauthorized accessEnforce HTTPS and encryption for data in transit and at rest, and apply least-privilege access across services and infrastructureRun security checks in CI/CD pipelines, maintain audit logs for sensitive operations, and set up rate limiting to protect against abuseMaintain a workflow, continuously identify risks, review access controls, patch vulnerabilities, and improve defenses as systems evolveIntegrate and secure crypto wallet flows in production — signing, transaction validation, and key managementCollaborate across product, data, and infrastructure to ship features end-to-endWrite clean, maintainable, well-tested, and well-documented codeRequirementsPrevious experience in fullstack, backend-focused software engineering, security engineering, or crypto/web3 developmentStrong experience building backend services and APIsSolid understanding of relational databases, query optimization, and schema design for performance at scaleExperience 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 designExperience securing API routes and endpoints — proper auth middleware, route guards, role-based access control, and scoped permissionsUnderstanding of how to handle sensitive data — PII, tokens, credentials — including encryption at rest, masking in logs, and secure storage practicesExperience running and debugging production systemsFamiliarity with modern frontend frameworksHands-on experience running and maintaining containerized workloads in cloud environmentsNice to HaveExperience hardening production systems, database access controls, audit logging, and vulnerability scanning in CI pipelinesFamiliarity with the crypto industry, including core blockchain concepts and onchain dataExperience with data-focused platforms (e.g. Dune Analytics, The Graph) and production-grade RPC node integration and monitoringSalary: $36,000 - $42,000 USDFully remote, with preference if based in Brazil.
