Senior Software Engineer — Platform & Distributed Systems (XTM Foundation)

About This Opportunity

We are representing a confidential cybersecurity technology organization seeking a Senior Software Engineer — Platform & Distributed Systems to join their cross-product engineering foundation team. This is a remote opportunity based in France.

Our client is building open-source solutions for cyber threat management, trusted by thousands of organizations globally. You'll join a technical foundation team responsible for architecture, quality, and shared tooling across multiple interconnected products in their security platform suite.

This is a high-impact, hands-on role where you'll be the technical owner of ambitious infrastructure challenges — designing architecture evolution to significantly increase data processing capacity. You'll define patterns and standards that govern how products communicate, scale, and evolve, working closely with product engineering teams to turn architectural vision into reality.

Responsibilities

• Lead the design and implementation of architecture evolution targeting significant improvement in data processing throughput and scalability
• Identify and resolve bottlenecks across the current data pipeline (ElasticSearch, PostgreSQL, RabbitMQ, Redis) through rigorous profiling, benchmarking, and architectural analysis
• Evaluate and recommend infrastructure and messaging technologies, alternative graph databases, CQRS/event sourcing patterns, and validate them through hands-on prototyping
• Define and enforce cross-product standards for inter-service communication, data consistency, and system observability
• Build performance testing infrastructure from the ground up, establishing continuous performance monitoring as a first-class engineering practice
• Collaborate with product engineering teams to roll out architectural changes progressively and safely, with zero-downtime migrations where possible
• Contribute to shared libraries, common patterns, and platform-level tooling that raise the bar for all product teams
• Stay current with the distributed systems and data engineering landscape, bringing well-evaluated proposals to the team

What We're Looking For

• 8–12 years of experience building and operating distributed, high-throughput systems in production environments
• Proven track record designing architectures for data-intensive platforms (data pipelines, event-driven systems, graph databases, or equivalent)
• Deep understanding of distributed systems fundamentals: consistency models, partitioning, replication, backpressure, fault tolerance, and observability
• Broad knowledge of backend languages and ecosystems — you've worked with multiple languages and paradigms, and you know how to pick the right tool for the job
• Deep familiarity with data storage and messaging technologies — hands-on experience with a range of databases (relational, search, graph, columnar) and message brokers, understanding trade-offs between them
• Ability to build performance benchmarks from scratch and translate results into clear architectural decisions
• Excellent system design and written communication skills — you can turn complex tradeoffs into actionable proposals
• Comfortable working in a remote-first, async culture with teams across multiple time zones; clear communicator in English
• Autonomy and ownership mindset: you drive problems to resolution without waiting for direction, and you enable others rather than becoming a bottleneck

How We Work With You

When you apply through Get A Job.ai, our talent team will review your background and schedule an initial screening call to discuss your experience with distributed systems and platform engineering. We'll assess fit for both the technical requirements and the remote-first, collaborative culture our client has built.

Once we align on the opportunity, we'll submit your profile directly to our client for consideration. You'll then enter their interview process, which typically includes technical discussions with staff engineers and leadership across their product teams.

Important: Please apply only through Get A Job.ai. Do not attempt to contact the client directly, as this is a confidential search and direct applications cannot be considered through our engagement.

Pay

Compensation details will be discussed during the screening process and are competitive for senior platform engineering roles in the European cybersecurity sector. Our client offers equity participation and a comprehensive remote-work benefits package.

Get A Job.ai is an equal opportunity employer. We welcome candidates of all backgrounds and experiences to apply.
