The client has made it clear that they value engineers based on their performance in a real working environment, not on artificial interview exercises or theoretical problem-solving detached from production realities. Requirements: Strong experience as a Senior Full Stack Engineer, with clear ownership of both backend and frontend production systems. Solid experience in backend engineering with Node.js in real-world production environments. Expertise in frontend engineering with React or similar modern JavaScript frontend frameworks. Understanding of design, build, and maintain complex web applications and APIs that support meaningful business workflows. Strong experience working with relational databases, application data models, and production data access patterns. Knowledge of PostgreSQL or similar relational database technologies in production systems. In-depth understanding of REST APIs, asynchronous workflows, distributed integration patterns, and service-based application design. Experience integrating with third-party APIs and external systems in production environments. Ability to work effectively in evolving codebases and make good engineering decisions without requiring excessive structure or hand-holding. Expertise in debugging and troubleshooting across application logic, integrations, and production issues. Ability to balance delivery speed with long-term maintainability in a startup or high-growth environment. Nice to have: Experience working in startup or hypergrowth environments where engineers are expected to take ownership and move quickly. Familiarity with Redis, caching strategies, job processing, or event-driven application behavior. Exposure to Python and collaboration with AI or data-oriented systems. Experience building or supporting systems with high throughput, near-real-time workflows, or operationally sensitive business logic. Background in AdTech, MarTech, call tracking, attribution platforms, lead generation systems, or analytics-heavy products. Experience building internal operational tooling and admin workflows for technical or business users. Exposure to cloud-native environments and scalable distributed systems. Experience collaborating closely with technical founders, product leadership, or senior engineering stakeholders. Responsibilities: Design, build, and maintain production-grade application features across both backend and frontend systems, with strong attention to scalability, performance, reliability, and maintainability. Develop backend services and APIs using Node.js to support platform capabilities such as workflow orchestration, system integrations, feature logic, internal tooling, and real-time operational processing. Build and enhance frontend applications using React or similar modern frontend technologies to support dashboards, management interfaces, internal tools, and user-facing platform capabilities. Take ownership of significant technical areas and deliver solutions with minimal day-to-day oversight, while collaborating closely with founders and other senior engineers. Work on systems that support high-volume workflows, external integrations, and operationally important product capabilities where responsiveness and reliability matter. Implement and maintain integrations with external partner platforms, APIs, and data-driven systems, including CRM platforms, call-tracking systems, and other third-party services that are central to the product ecosystem. Contribute to architectural discussions and technical decisions related to application structure, data flow, performance optimization, maintainability, and production stability. Investigate and resolve production bottlenecks, system issues, and integration challenges in a practical, efficient manner. Collaborate with AI and data engineering team members where needed to connect backend and frontend product capabilities with intelligent workflows such as transcription, data extraction, scoring, or analytics-driven features. Help establish sound engineering patterns and raise the quality bar as the team scales, including code quality, implementation discipline, and pragmatic technical decision-making. Participate in a fast-moving engineering culture where new features, experiments, and improvements are shipped continuously. We offer: US and EU projects based on advanced technologies.
