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

Filigran, founded in October 2022, stands out in the cybertech ecosystem for its commitment to revolutionizing cyber threat management with a proactive approach. We're looking for a Senior Software Engineer with deep expertise in distributed systems and platform engineering to join the XTM Foundation team. You will be the technical owner of our most ambitious infrastructure challenge: designing the architecture evolution to increase data processing capacity. This is a high-impact, hands-on role. You won't just design on paper — you'll prototype, benchmark, validate, and help teams implement.

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 across the XTM Suite; Collaborate with product engineering teams (~60 engineers) to roll out architectural changes progressively and safely, with zero-downtime migrations where possible; Contribute to the XTM Foundation team's broader mission: 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

Requirements

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; Deep familiarity with data storage and messaging technologies; Ability to build performance benchmarks from scratch and translate results into clear architectural decisions; Excellent system design and written communication skills; Comfortable working in a remote-first, async culture with teams across multiple time zones; clear communicator in English; Autonomy and ownership mindset

Benefits

Competitive pay + equity; Remote-first, flexible, and balanced; Your setup, your choice - pick the gear that works for you; Twice-a-year gatherings - we meet in person for regional and global offsites to connect, collaborate, and strengthen our culture beyond the screen
