About the Role:
As a Full Stack Software Engineer in the Core Platform Engineering team, you'll be responsible for building and scaling the services and data systems that power our cybersecurity products. You will own APIs, data pipelines, and storage layers end to end, working on high-impact engineering problems with a focus on performance, scalability, and reliability. This role is best suited for engineers who love shipping production services, writing clean code, and want to grow their skills in distributed system design, data modelling, and platform infrastructure.
What You’ll Do :
- Design, build, and operate backend services and RESTful APIs in NodeJS + TypeScript and frontend in React, HTML, CSS, JavaScript.
- Design data models and manage databases (PostgreSQL, MongoDB, Elasticsearch) for performance and reliability, including indexing, query tuning, and schema evolution.
- Drive performance optimization across the backend - API latency, query plans, caching strategy, connection pooling, and throughput under load.
- Design for scale and failure: idempotency, retries, backpressure, rate limiting, and graceful degradation.
- Work with asynchronous and event-driven patterns using queues and streams (Kafka, RabbitMQ, SQS, or similar).
- Implement observability practices - structured logging, metrics, tracing and alerting.
- Work with containerized environments (Docker, Kubernetes) and contribute to CI/CD pipelines and infrastructure automation.
- Collaborate with cross-functional teams (Product, Frontend, Infra) to deliver features end to end.
- Participate in code reviews, design reviews, technical discussions, and mentoring when applicable.
What We're Looking For:
- 3+ years of backend development experience building and running production services.
- Strong in Node.js/TypeScript (or Golang/Python), with hands-on coding and debugging skills.
- Solid knowledge of SQL/NoSQL data modeling and performance tuning - explain plans, indexing strategy, and handling large tables and collections.
- Experience with performance optimization - profiling, load testing, identifying bottlenecks, and reducing latency and resource usage.
- Hands-on experience with caching (Redis or similar) and concurrent systems, along with message brokers and stream processing (Kafka, RabbitMQ, NATS).
- Good understanding of data structures, algorithms, and problem solving.
- Working knowledge of system design fundamentals and a willingness to improve architectural thinking.
- Comfortable with Linux, Git, and debugging issues in production environments.
- Willingness to learn, take feedback, and grow with structured mentorship.
Nice to Have
- Experience with Elasticsearch or OpenSearch at scale - mappings, sharding, and aggregations.
- Familiarity with Kubernetes, Docker, CI/CD, Linux, and RESTful API standards.
- Exposure to cloud-native development on AWS, GCP, or Azure.
- Experience in cybersecurity product development or interest in the space.
- Bonus: experience building LLM or agent-based features in production (tool calling, prompt engineering, evals).
