Senior Software Engineer – Platform, Distributed Systems

This is a fully remote position, open to applicants in France.

📋 Description

• Oversee the design and execution of architecture advancements aimed at significantly enhancing data processing efficiency and scalability.

• Detect and address bottlenecks within the existing data pipeline (ElasticSearch, PostgreSQL, RabbitMQ, Redis) through thorough profiling, benchmarking, and architectural evaluation.

• Assess and suggest infrastructure and messaging technologies, explore alternative graph databases, and implement CQRS/event sourcing patterns, validating them through practical prototyping.

• Establish and uphold cross-product standards for inter-service communication, data consistency, and system observability.

• Develop a performance testing infrastructure from scratch, establishing continuous performance monitoring as an essential engineering practice throughout the XTM Suite.

• Partner with product engineering teams (approximately 60 engineers) to incrementally and safely implement architectural modifications, ensuring zero-downtime migrations when feasible.

• Contribute to the broader mission of the XTM Foundation team: creating shared libraries, common patterns, and platform-level tools that enhance the quality for all product teams.

• Remain updated on the landscape of distributed systems and data engineering, presenting well-considered proposals to the team.

⛳️ Requirements

• 8–12 years of experience in constructing and managing distributed, high-throughput systems within production settings.

• Demonstrated success in designing architectures for data-driven platforms (data pipelines, event-driven systems, graph databases, or similar).

• Profound understanding of distributed systems principles: consistency models, partitioning, replication, backpressure, fault tolerance, and observability.

• Extensive knowledge of backend programming languages and ecosystems — you have experience with various languages and paradigms, and you know how to select the appropriate tool for the task.

• Strong familiarity with data storage and messaging technologies — you possess hands-on experience with a variety of databases (relational, search, graph, columnar) and message brokers, along with a comprehension of their trade-offs.

• Capability to create performance benchmarks from the ground up and interpret results into clear architectural choices.

• Exceptional system design and written communication skills — you can distill complex trade-offs into actionable proposals for engineers and leadership.

• Comfortable in a remote-first, asynchronous culture with teams across different time zones; proficient communicator in English.

• A mindset of autonomy and ownership: you tackle problems proactively without waiting for guidance, and you empower others rather than becoming a bottleneck.
