Job Description & How to Apply Below

Yugabyte is the company behind YugabyteDB , the AI-ready, multi-modal, distributed PostgreSQL database for cloud-native apps. Trusted by industry leaders including Shopify, Paramount+, GM, Kroger, Fiserv, and NPCI, YugabyteDB has been deployed in over 100 countries and powers more than 5 million clusters worldwide. Together, our hard-working team of experts and our industry-leading technology are uniquely positioned to meet the demands of modern workloads: geo-distributed, ultra-resilient, and built to scale without limits.

Our Yugabeings (distributed, like our database) span 12+ countries and multiple time zones, sharing expertise from diverse backgrounds and industries.

Technical Support Engineer Remote, (UK time zone)

At Yugabyte , We are on a mission to become the default transactional database for enterprises building cloud-native applications. YugabyteDB is our PostgreSQL-compatible distributed SQL database - resilient, scalable, and built to run anywhere. We're not just building software; we're watching major enterprises throw out Oracle and build something better, and the people who help them get there are the ones sitting in this team.

About

This Role

We're looking for someone who gets genuinely excited when a customer's database is on fire, because they are eager to dive in and help.

This isn't a "ticket-monkey" role. You won't be copy-pasting canned responses into a queue. You'll be working live cases - distributed systems behaving unexpectedly, replication lag climbing, certificates expiring in production - alongside a global team that actually cares about getting to the root of things.

You'll learn YugabyteDB, cloud infrastructure, and distributed systems the way everyone learns them best: by necessity, with great people around you.

What You'll Do
  • Triage and own technical support tickets from enterprise customers, collaborating with a global team across time zones
  • Investigate incidents methodically - reading logs, running queries, tracing replication issues - and surface the root cause, not just the fix
  • Write clear internal notes and handover documentation so the next engineer can pick up exactly where you left off (this is not optional; notes are the job)
  • Attempt repros of customer issues and document the steps for others to replicate
  • Escalate to engineering when warranted, with enough evidence that they can act immediately
  • Contribute to the team's shared knowledge base and improve how we handle problems we've seen before
  • Be the calm, professional voice a customer hears when their weekend just got complicated
What We’re Looking For

You are the right person if:

  • You jump in. When something unfamiliar comes across the queue and no one's claimed it, your instinct is to click it and start reading, not to wait.
  • You embrace not knowing the answer yet, and you see that as the start of something, not a reason to hold back.
  • You're not afraid
  • You have a technical background in any discipline — software, systems, automotive, aerospace, networking, electronics, whatever.
  • If you have solved real problems under real pressure with tools and documentation, that counts.
  • You have familiarity with Linux tools -- you have used the tools find and grep to navigate a file system Note taking is how you gain context . You write down what you found, what you tried, and what you plan to do next, every time. It builds confidence for both you and the customer

You may also have:

  • Experience with any relational database — even if it's just writing queries
  • Experience on a support team for a large software product
Why This Team

Our support engineers don't just resolve tickets - we are incident commanders. We run incident channels, hold calls with customer teams and stakeholders, write CEs (customer escalations) that go directly to our database engineering team, and sometimes catch product bugs before engineering does.

  • Are curious, what others view as problems, we view as opportunities to learn something new
  • Work with highly technical issues that require precise mitigation
  • Dig into source code themselves when they need to understand why a validation is failing
  • Know that some issues need overnight support, so we prepare the offshore teams…
