About the Role:

The Search and Discovery team at TaskRabbit strives to unlock growth by delivering a next generation search experience for Clients and Taskers. As part of our product engineering team, you will get to work on our search technology, pricing solutions and marketplace dynamics to shape one of the most critical drivers of our business.

As a backend Senior Software Engineer, you'll be one of the leaders of our team helping to set our technical Search strategy by proposing creative and scalable solutions, de-tangling the complex into the simple and building the future of search. 

Our engineering team uses Ruby on Rails on the backend, React.js on the web frontend and React Native for our mobile applications. Our current search technology utilizes ElasticSearch, AWS and connects to internal machine learning APIs. We’re looking for people who are comfortable and interested in working with a little bit of everything with a growth mindset for bringing in new solutions and changing the paradigm. Our ideal candidate is a technical leader with experience building robust and scalable Search solutions. 

What you’ll be working on

You will be:

  • Designing, building, and maintaining marketplace product solutions 
  • Optimizing the results of Search to provide best in class search experience for Taskrabbit clients 
  • Improving search latency and relevancy using large scale data systems 
  • Taking part in the modernization of our codebase
  • Implementing semantic search and other advanced search capabilities
  • Integrating AI & Machine Learning capabilities 
  • Analyzing product or system gaps & issues to debug, resolve and suggest long term solutions 
  • Contributing to the growth and success of team members through code review, clear documentation, and mentorship
  • Collaborating with engineering, data, design, and product management to conceptualize new features and improvements for our client-facing applications 
  • Contribute to our technical roadmap of ongoing improvements, enhancements and updates

You should have:

  • Experience designing and developing search solutions 
  • 5-10 years of software development experience, comfortable working independently
  • 2+ years professional experience developing with Ruby on Rails or similar 
  • Experience with search and data storage technologies (ElasticSearch, OpenSearch, MongoDB, PostGresSQL or other) 
  • Experience building API-driven applications or endpoints
  • A working knowledge of advanced technologies related to Search & Machine Learning 
  • Experience integrating third party tools into existing systems
  • Familiarity with automated testing, JS build and packaging systems 
  • Understanding how to organize code across the stack
  • Exceptional written and verbal communication skills, especially for asynchronous collaboration 

It would be a plus if you have: 

  • Built a search solution from scratch (ex: early stage company or re-platforming, new feature build)  
  • Worked with ElasticSearch before
  • Integrated Machine Learning APIs 
  • A working understanding of AWS or cloud 
  • Experience with a/b testing frameworks such as Optimizely
  • Integrated data sources into a search platform 
  • A deep understanding of indexing
