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.

What’s in store for you?

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

Tech stack

• Python 3.14 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

• Pytest for automated tests - 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

What do you bring to the table?

• 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)

• Experience with Git

• 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.

Nice to haves

• 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)

• Experience in an agile development environment (SCRUM)
