Python Developer

Sparkland is one of the leading players in high-frequency trading. It's an industry that's evolving so fast, we're creating it in real time. And that's why we've made it our mission to set our own standards — using innovative strategies and state-of-the-art tech to make markets more liquid and efficient for everyone.

We are looking for a Mid-level Python Developer who thrives in fast-paced environments and enjoys building scalable backend systems. You’ll work on developing new microservices and improving existing ones that power key parts of our trading infrastructure. If you’ve built resilient, observable, and performant services — and enjoy writing asynchronous code and integrating with external systems — you might be a great fit.

Responsibilities

• Design, build, and maintain Python-based microservices supporting trading operations.
• Develop new features for internal systems (e.g., funding rates prediction, exchange automation).
• Extend our exchange connectivity by adding new markets.
• Route/handle data from trading across our internal systems.
• Troubleshoot and resolve production issues using observability tools (logs, metrics, alerts).
• Deploy and monitor services in a Kubernetes environment using Docker, CI/CD, and Helm.
• Collaborate closely with traders, C++ engineers, QA, and data teams to align on business needs.

Required skills and experience

• Minimum 4-5 years of backend development experience with Python.
• Strong experience with asynchronous programming and parallelism in Python.
• Proficiency in at least one modern Python web framework (FastAPI, Django, or Flask).
• Experience working with relational databases (PostgreSQL preferred).
• Comfortable with Docker and CI/CD tools (GitHub Actions, GitLab CI, Jenkins, etc.).
• Solid understanding of service monitoring using Sentry, Prometheus, or Grafana.
• Ability to diagnose and fix incidents in remote production environments.

Bonus points

• Experience with Kubernetes and Helm for scalable deployments.
• Familiarity with Kafka, RabbitMQ, or Redis PubSub for event-driven architectures.
• Experience with NoSQL databases (Redis, DynamoDB, etc.).
• Understanding of trading systems, high-volume data environments, or HFT workflows.

What we offer

• Flexible working hours and a healthy work-life balance.
• Remote-first team.
• The opportunity to work in a thriving, multicultural, fun environment in one of the world’s fastest-growing industries.
• Corporate workations: we regularly go on corporate trips to unique locations all over the world to work, explore the local culture, and get to know each other better.
