Product Engineer (Python) - Trading Systems

As part of the CandleKeeper Team at FTMO, you'll be responsible for the entire application lifecycle - analysis, implementation, maintenance and operation. You'd also take part in on-call and actively monitor and take care of issues.

The CandleKeeper team builds with AI coding agents: you write the spec, direct the agent, then review and test what it produces. Strict typing (Mypy), Ruff, multi-level tests and CI checks are the guardrails that keep generated code safe in production.

About ftmo

300+ amazing teammates. We’re a great team who learn from each other every day.🤜

Responsibilities

• The team is primarily building and maintaining systems for the integration of 3rd party Trading Platforms:

Monitoring of trading accounts

• System tracks the record of client accounts, their trading activity, and evaluates whether they are abiding by FTMO trading rules
• Data is ingested from the platforms and sent through multiple applications using Kafka as a messaging broker.
• Trading platform API bridge
• System that manages client accounts on the trading platform - Basic CRUD operations, and in the future will help with making changes to trading platform configuration - we have a lot of servers, and we need to keep the configuration unified across them
• Monitoring of historical symbol/security/instrument configuration
• Monitoring of trading activity
• System tracks activity (read counts of messages) generated by our clients, and when they get over thresholds, it sends messages to trigger actions - preventing hyperactive / runaway algos from overloading our systems

Custom integrations into platforms

• We have our own internal C++ plugins for some platforms. These plugins provide custom logic for our apps, for example, providing real-time data for our monitoring of trading accounts, or providing APIs for the trading platform bridge
• with a lot of asyncio and mandatory typing Kafka for near real-time event processing FastAPI with async endpoints and fully typed arguments for a clean OpenAPI schema TimescaleDB for storing trading data Google Cloud Storage with Apache IceBerg as a second-tier storage for trading data that is not needed in the main trading database SQLAlchemy Core for database modeling and querying data Django for database modeling for legacy reasons - the project started with Django Ruff for linting and formatting Mypy for type-checking
• We have tests covering multiple levels - unit-tests, system tests, and even integration tests Behave for end-to-end tests GitLab CI/CD for running automated tests, linting, security scans, and deployment Sentry for tracking errors Thanos/Prometheus for metrics storage and Grafana for dashboards over them ECS logging and Kibana for viewing logs Docker and Kubernetes for running our apps
• AI coding agents
• (e.g., Claude Code) for implementation, code review and writing tests

Requirements

• Python 3.14
• 3+ years in software engineering (e.g., SW Developer, SW Engineer, SDET, QA Automation Engineer or similar positions).

Experience with modern, typed, and concurrent Python

• Experience with web frameworks like FastAPI, Django, Flask, etc.
• Experience with messaging systems like Kafka, RabbitMQ, SQS, etc.
• Experience with relational databases like PostgreSQL, MySQL, etc.

Experience writing tests (Pytest)

• Hands-on experience with AI coding agents (e.g., Claude Code, Cursor, Codex) on real code: you can say where they helped, where they failed, and you stand behind what you ship
• Czech/Slovak + English proficiency at minimum B2 level.

Preferred

• Master's degree in Computer Science, IT, or a related field.
• Knowledge of Typescript, C++
• Experience with containers and Kubernetes
• Experience with Linux
• Experience building tooling for AI agents or their guardrails (custom agents, MCP servers, agent skills, or CI checks for AI-written changes)
