- 4–6 years of hands-on machine learning experience.
- At least 2 of those years spent on search result ranking, recommendations, or personalisation — for a live product with real users. Academic projects, competitions, and internal prototypes do not count towards this.
- Strong programming in Python and strong SQL.
- Experience handling very large datasets using tools such as Spark, PySpark, or Hive.
- Practical experience with the machine learning techniques used for ranking and recommendations.
- Experience designing and running A/B tests, and the ability to say clearly what your change did to a business number.
- Experience working with text data — matching what a user is looking for against what a job description says. Experience with Indian-language or transliterated text is a solid plus.
- The ability to explain a technical trade-off in simple language to a product manager or business stakeholder

- Improve the quality of search results, so that the most relevant jobs appear at the top.
- Work out what a user actually means when they type a search — the role, the locality, the experience level,



the pay they expect — even when the query is a few words typed in Hindi, Hinglish or a regional language, with spelling that follows how the word sounds.
- Make distance a first-class part of ranking. For most of our roles, a job close to home is a fundamentally better result than a well-matched one across the city.
- Keep results genuine and current — filled or low-quality listings ranked highly are a bad user experience, so quality and freshness are part of the model, not an afterthought.
- Build and improve recommendation models that suggest relevant jobs to jobseekers and relevant candidates to recruiters.
- Decide how "good" is measured, and prove your changes helped by running experiments on live traffic.
- Work with very large volumes of user activity data to build the inputs your models need.
- Partner with product managers and engineers to take models live, and present results clearly to both technical and non-technical audiences.
