Full-Stack Developer
About Zeliot
At Zeliot, we are redefining the future of real-time data streaming, empowering enterprises and developers to unlock the full potential of their data with speed, simplicity, and scale. We envision a world where data moves seamlessly, insights are delivered instantly, and innovation happens at the speed of thought.
To bring this vision to life, we created Condense, a next-generation all-in-one data streaming platform that radically simplifies how real-time applications are built, deployed, and scaled. Condense eliminates the complexities traditionally associated with infrastructure management through fully managed Kafka, intelligent autoscaling, and a Bring Your Own Cloud (BYOC) deployment model, freeing developers from operational overhead and enabling them to focus entirely on creating new real-time experiences.
With an AI-driven development framework and a Custom Transformation Framework, Condense allows developers to write, test, and deploy stream processing logic in their preferred programming languages, accelerating innovation and shortening development cycles. This approach enables enterprises to bring new applications to market faster and operate at true cloud-native speed, supported by optimized infrastructure utilization and up to 40–60% reduction in total cost of ownership (TCO), all while maintaining data sovereignty, performance, and scalability across cloud environments.
Driven by deep domain expertise across connected mobility, IoT, and large-scale data ecosystems, Zeliot extends beyond platform innovation to deliver the complete ecosystem enterprises need to realize their real-time data ambitions. By combining advanced streaming technology with contextual intelligence and industry focus, Zeliot enables organizations to build, scale, and manage real-time applications with exceptional efficiency and measurable business impact.
At Zeliot, streaming becomes effortless, development becomes frictionless, and innovation becomes continuous, transforming how enterprises turn data into decisions and vision into value.

- Architect, create, and maintain database schemas, relationships, and efficient data models in PostgreSQL or MySQL.
- Optimize queries, indexes, and data access patterns for performance and scalability.
- Implement and maintain observability and monitoring using tools such as Prometheus and Grafana.
- Troubleshoot and debug API issues, backend bottlenecks, and production incidents effectively.
- Write automated unit, integration, and end-to-end tests to ensure high code quality.
- Collaborate with cross-functional teams (Product, QA, DevOps, Design, Data) to ship high-impact features.
- Deploy and manage applications on AWS, Azure, or GCP using CI/CD pipelines and container technologies such as Docker and Kubernetes.
- Contribute to code reviews, maintain best practices in software design, and ensure adherence to coding standards.
- Continuously explore and learn emerging technologies to improve efficiency and scalability.
- Demonstrate problem-solving skills through debugging, performance tuning, and design optimization.
Qualifications/Skills:
- 2-3 years of hands-on experience in full stack development.
- Strong proficiency in:
- Backend: Node.js (Express.js, NestJS)
- Frontend: React.js, Next.js, Redux/Context API
- Database: PostgreSQL / MySQL (schema design, indexing, joins, and data type optimization)
- API: REST and GraphQL design, implementation, and security.
- Proficient in JavaScript (ES6+), TypeScript, and asynchronous programming.
- Experience with Git, Yarn/NPM, and Visual Studio Code or equivalent tools.
- Familiarity with observability, logging, and tracing concepts — using tools such as Grafana & Prometheus.
- Knowledge of cloud services (AWS, GCP, Azure) including compute, storage, and managed databases.
- Understanding of CI/CD pipelines, Docker, and Kubernetes for modern deployments.
- Strong grasp of software design patterns, system architecture, and scalability principles.
- Excellent problem-solving, debugging, and analytical abilities.
- Bachelor’s or master's degree in Computer Science, Information Systems, or a related technical field.
- Demonstrated experience working in an Agile or Scrum environment.
- Strong communication and collaboration skills.
- Self-motivated, quick learner, and capable of working autonomously.
- Passionate about writing clean, maintainable, and efficient code.
- Curious about new technologies and approaches to problem-solving.
Good to have skills:
- Experience with microservices architecture or event-driven systems.
- Exposure to Kafka, Redis, or message queues.
- Familiarity with automated testing frameworks (Jest, Cypress, Mocha).
- Understanding of security best practices (JWT, OAuth, HTTPS, CORS).
What We Offer
- Competitive compensation and comprehensive benefits.
- Opportunity to work on a cutting-edge real-time data platform.
- High ownership, autonomy, and impact.
- Collaborative, fast-paced, deep-tech environment.
- Strong focus on learning, growth, and long-term career development.
