• Improve customer activation — optimise the journey from registration to first transaction and drive faster time-to-value.
• Drive customer expansion and retention — develop strategies to grow customers from Air → Hotels → Payments, increase transaction frequency and build long-term customer value.
• Own growth analytics — track key metrics such as CAC, LTV, activation, retention and contribution, and use data to identify what works and what to scale.
   

What success looks like
 

We are not measuring success by traffic, followers or the number of registered accounts. You’ll be focused on:

• Growth in active transactional customers
• Increased multi-product adoption
• Growth in customer contribution
• Improved 30 / 90 / 180 / 365-day retention
• Efficient CAC and payback by acquisition channel

The team is based in San Francisco, a 10-hour time difference. Because of that:

• Working hours shift into the evening - roughly until 9-10 PM Kyiv time

• Calls with the team two to three times per week at the start, one to two later on

• Everything else is async, you plan your own day

• Evening availability on agreed days is mandatory and not open for renegotiation after you start

If evening hours don’t work for you, it’s better not to spend time applying.

Requirements
 

Building processes from scratch

• Experience joining a project with no QA in place and building everything yourself

• Ability to set up a manual process from zero: critical flow map, test plan, regression suite, release checklist, bug workflow

• Experience with CI/CD and how tests live inside a pipeline

AI testing

• Hands-on experience testing products with an LLM or ML underneath

• Understanding of how to verify non-deterministic output, where there is no single correct answer to assert against

• Experience with evaluation sets, scoring response quality, and catching regressions after a model or prompt change

• Familiarity with common failure modes: hallucinations, unstable responses, false refusals
 

API and backend

• Confident API testing with Postman or equivalent

• Ability to read logs and localise an issue to the device, the app, or the backend

• Working understanding of cloud services

Communication

• English at Advanced (C1) level or above — fluent spoken and written, no pauses to find words

• Comfortable holding technical discussions directly with a CTO

• Self-driven: nobody will hand you tasks every morning
 

Strong pluses

• Experience testing products where an app works together with a physical device

• Understanding of BLE: pairing, reconnection, behaviour on connection loss, data sync

• Experience with OTA firmware updates delivered through an app

• Working with audio as test data

• Experience at early-stage startups where processes don’t exist yet and have to be created

• Crash and feedback triage during beta, with Sentry or Crashlytics

• Understanding of privacy requirements: verifying data deletion and recording indicators

What you’ll be doing

• Regression testing ahead of weekly releases

• Feature testing before go-live

• Exploratory testing across device → cloud → app

• Building the QA process from scratch and growing it over time

• Auditing existing automated tests and gradually extending them

• Bug and crash triage during beta
