Apply for Senior Technical Support Engineer

Affinity is seeking a Senior Technical Support Engineer on behalf of a leading technology company building next-generation distributed messaging and connectivity solutions.

This is a hands-on technical support role for someone who loves solving problems, thrives on working directly with customers, and enjoys diving deep into distributed systems, networking, and messaging technologies. You’ll join a global remote team that values curiosity, ownership, and technical precision.

Key Responsibilities

• Provide advanced technical support to enterprise customers, including design discussions, issue triage, and troubleshooting of distributed systems and messaging infrastructure.
• Diagnose and resolve complex issues across networking, software, and infrastructure layers — from misconfigurations and outages to architecture or upgrade challenges.
• Conduct root-cause analyses (RCA) and create clear technical documentation and knowledge-base articles.
• Collaborate with internal engineering and product teams to share insights and improve reliability and customer experience.
• Contribute to process and tooling improvements that enhance operational efficiency and customer success.
• Participate in an on-call rotation to support production environments.

Required Skills & Experience

• 5+ years of technical support experience (L2/L3) in production or enterprise environments.
• Deep Linux/Unix troubleshooting and command-line proficiency.
• Strong understanding of networking protocols and security (TCP/IP, UDP, TLS, HTTP, DNS, certificates, proxies).
• Proven ability to analyze and stabilize distributed systems.
• Strong written and verbal communication skills, including the ability to document and explain technical issues to customers and internal teams.

Preferred Qualifications

• Experience operating or supporting messaging technologies such as Kafka, RabbitMQ, MQTT, JMS, AMQP, or NATS.io.
• Familiarity with Go (Golang) for scripting or debugging.
• Exposure to IoT architectures and cloud vendor solutions (AWS, GCP, or Azure).
• Knowledge of security, virtualization, and RAFT consensus algorithms.
• Experience contributing to or engaging with open-source communities.

Why Join

• Be part of a global, remote-first team supporting cutting-edge distributed messaging systems used in critical, high-scale environments.
• Work on technically challenging issues that push the boundaries of connectivity, reliability, and scalability.
• Influence processes and tooling in a growing support organization that values technical excellence and customer impact.
• Competitive compensation and opportunities for long-term growth.
