About the role

Hostaway is seeking a highly specialised

Senior Software Development Engineer in Test

with a background in performance testing to join our team and ensure our platform performs flawlessly at scale. As we continue our rapid growth, performance and reliability are critical to our success.

Your Mission

As a Senior SDET specialising in Performance Testing, you'll design, implement, and execute sophisticated load testing strategies that ensure Hostaway can handle massive scale while maintaining exceptional user experience.


You are a performance engineering expert who thinks beyond simple load generation. You craft realistic scenarios that mirror production traffic patterns, design complex load profiles that expose bottlenecks before they reach production, and build the tooling and infrastructure needed to test at scale. You understand that modern performance testing is about testing as code, production traffic replay, and continuous performance validation integrated into CI/CD pipelines.


Driven by data and metrics, you'll establish performance baselines, and create automated performance regression tests that catch degradations before they impact customers. You'll work closely with engineering teams to identify performance bottlenecks, optimise system behaviour, and ensure that every release meets our stringent performance standards, even when deploying on a Friday.

An Average Day for a Senior SDET (Performance Testing)

10:00-10:15

Quick team stand-up. The team is planning a major feature release, so you initiate a session to discuss performance requirements, load expectations, and potential bottlenecks.

10:30-14:00

Analysing production traffic patterns to design realistic load scenarios for an upcoming test. You craft a new script that mirrors actual user behaviour, including realistic think times and multi-step user journeys.

14:00-15:00

Joining a collaborative session with the engineering team to review performance test results from last night's CI run. You've identified a regression in API response times and work together to pinpoint the root cause.

15:00-16:00

The product manager and tech lead want to discuss a new integration with a third-party booking platform. Your input regarding the performance implications, load testing strategy, and test data requirements is invaluable.

16:00-18:00

Focus time to build test data provisioning scripts, refine your performance testing framework, and set up automated performance budgets in the CI/CD pipeline.
