Who we are:
Adaptiq is a technology hub specializing in building, scaling, and supporting R&D teams for high-end, fast-growing product companies in a wide range of industries.
About the Product:
Our client operates a global B2B distribution platform connecting supply partners and third-party resellers through real-time APIs and microservices.
The system delivers end-to-end search, pricing, booking, and update notifications across multiple continents, handling billions of daily requests.
It integrates diverse external feeds for availability, rates, taxes, and policies, processes data in asynchronous pipelines, and exposes flexible interfaces to accommodate various consumer needs.
Deployed across cloud regions, the platform uses persistent databases, in-memory caches, and queuing layers to ensure low-latency responses under heavy load.
Engineers face challenges in distributed system design, performance tuning at scale, resilient error handling, and continuous delivery of critical revenue-driving services.
About the Role:
This senior position sits in the core infrastructure team responsible for the mission-critical search and transaction services at the heart of the platform.
You will take full lifecycle ownership of key microservices, from initial design and implementation through deployment, monitoring, and ongoing optimization.
Working in bi-weekly sprints, you will collaborate with product managers, architects, and DevOps to deliver new features, troubleshoot production incidents, and drive system performance improvements.
In this role you will shape service contracts, maintain event-driven workflows, integrate external APIs, enforce coding standards, and expand automated test coverage.
You will mentor peers, influence technical direction, and directly impact the reliability and scalability of a high-volume platform.
Key Responsibilities:
β’ Design, implement, and maintain scalable APIs and microservices that support high-volume search and booking workflows.
β’ Integrate, normalize, and process data from multiple external services into flexible downstream interfaces.
β’ Optimize service performance and maintain low-latency responses under heavy concurrency and global traffic.
β’ Build and maintain automated unit and integration tests, ensuring code quality and preventing regressions.
β’ Troubleshoot production issues, collaborating with DevOps on deployments, monitoring, and incident response.
β’ Participate in architecture and design reviews to drive resilience, scalability, and service decomposition.
β’ Own one or more services as the designated system owner, ensuring uptime, observability, and comprehensive documentation.
β’ Collaborate with stakeholders to translate complex business requirements into robust technical solutions.
Required Competence and Skills:
β’ At least 5 years of professional backend development experience.
β’ Proven track record designing and implementing RESTful APIs and microservices.
β’ Strong proficiency in JavaScript and Node.js (e.g., Express or equivalent frameworks).
β’ Deep understanding of asynchronous programming, event-driven patterns, and related pitfalls.
β’ Solid grasp of fundamental design principles for distributed, high-scale applications.
β’ Experience with data stores such as Redis, MongoDB, MySQL, or similar technologies.
β’ Familiarity with queuing solutions like RabbitMQ, SQS, Gearman, or equivalents.
β’ Skilled in writing automated tests and maintaining CI/CD pipelines.
β’ Proficient with Git for version control.
β’ Practical experience with cloud platforms (AWS, GCP) and Linux environments.
β’ Understanding of containerization and deployment workflows in a DevOps context.
