• Optimize System Performance: Profile and troubleshoot performance issues, ensuring our products continue to deliver a seamless experience under increasing load.
• Maintain and Evolve Architecture: Contribute to architectural discussions, influence technical decisions, and help evolve our stack with new technologies and frameworks.
• Take Ownership: Participate in on-call rotations when needed, and assume operational responsibility for the services you develop.

What we look for in you

• 5+ Years of Software Engineering Experience: Demonstrated expertise in both backend and frontend development for modern, cloud-based applications.
• Fullstack proficiency: Strong skills in Java or Python. Hands-on experience with JavaScript/TypeScript and front-end frameworks (Vue.js or React). Enthusiasm to learn new technologies is a must.
• Cloud & Containerization: Experience with AWS or GCP, Kubernetes, and Docker for deploying and scaling applications.
• Quality Focus: Passionate about code quality, testing, and continuous refactoring to maintain high engineering standards.
• Excellent Communication: Ability to collaborate effectively in cross-functional teams; proficiency in English (speaking and writing).
• Mentorship & Leadership: Willingness to guide junior engineers and drive technical initiatives across the organization.

Bonus Points

• Exposure to AI/ML: Familiarity with AI, prompt engineering, or integration of LLMs.
• Product-Led Growth (PLG): Knowledge of PLG frameworks, continuous onboarding strategies, or experience with tools like Mixpanel, Pendo, and Hotjar.
• B2B/SaaS Experience: History of shipping software in a SaaS environment.
• Open Source Contributions: Active participation in open source communities or related technical forums.

Our Technology Stack

• Cloud Infrastructure as Code: We operate on AWS and GCP across multiple regions, managing our infrastructure with Spacelift and Terraform.
• Container Orchestration: Kubernetes (EKS and GKE) orchestrates our containerized services, configured with Helm and FluxCD.
• Backend Services: Predominantly built in Java (Quarkus) and Python, with a focus on high performance and scalability.
• Event-Driven Architecture: Apache Kafka and RabbitMQ power our messaging and event-driven flows.
• Databases: PostgreSQL, ClickHouse, MySQL, and Elasticsearch serve our diverse data storage needs.
• Monitoring & Logging: We rely on Prometheus, Grafana, and the ELK stack for observability and performance insights.
