Qualifications

• 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; experience with multiple languages and paradigms.
• Hands‑on experience with databases (relational, search, graph, columnar) and message brokers; understand trade‑offs.
• Ability to build performance benchmarks from scratch and translate results into architectural decisions.
• Excellent system design and written communication skills; able to propose actionable plans.
• Comfortable in a remote‑first, async culture with teams across time zones; fluent in English.
• Autonomy and ownership mindset; drive problems to resolution and enable others.

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 through profiling, benchmarking, and architectural analysis.
• Evaluate and validate infrastructure and messaging technologies via hands‑on prototyping.
• Define and enforce cross‑product standards for inter‑service communication, data consistency, and observability.
• Build performance testing infrastructure and establish continuous performance monitoring across the XTM Suite.
• Collaborate with product engineering teams to roll out architectural changes with zero‑downtime migrations where possible.
• Contribute to shared libraries, patterns, and platform‑level tooling for all product teams.
• Stay current with distributed systems and data engineering landscape, bringing proposals to the team.
