Front-end Software Engineer

San Francisco, California, United States of America


Clara Labs

Clara Labs is establishing a new class of virtual assistant that understands you like a person, but operates at the scale, speed, and persistence of a machine. To do this, we mix intelligent automation software with remote human contractors to form an efficient, distributed remote-knowledge-work service.

Our initial focus is on scheduling meetings via email. We believe that by reducing anxieties caused by cluttered inboxes, complex calendars, and juggling preferences and calendars, customers can have more time to focus on what matters.

We aim to make automated assistants a truly everyday productivity tool. Our approach differs from traditional machine assistants (think: Siri) in our deep focus on conversation quality and human-like product flexibility. We build technology to maximize user experience, without constraining ourselves to the latest technology bandwagon. As a result, we’ve been delivering a highly reliable and flexible natural language interface from day one.

Engineering at Clara

Shipping early and often leads to better products.

As an example, we scheduled thousands of meetings for our first customers manually before building any software. We’ve found that persistent iteration leads to tighter feedback loops between our customers, our contractors, and our product development team.

Ownership enables contributors to do their best work.

Critical thinking and invention are key virtues of each team member. Individuals identify problems and solutions, and are responsible for driving projects to completion.

We're taking on problems that are previously unsolved: building large-scale human-machine learning hybrid systems. Here are a few types of problems engineers at Clara work on:

  • Semantic interpretation of received messages; includes conversation modeling and natural language processing.
  • Modeling highly complex calendars and meeting preferences across many different usage patterns.
  • Formulating “bite-sized” tasks and distributing real-time work load across a network of international human contractors.
  • New user interfaces for combining machine learning and human expertise to process message-based tasks; we’ve built a “mail client” and “calendar client” like no other.
  • Engineering underlying services (such as messaging protocols, calendaring servers, real-time work dispatching) to come together reliably and support the items above.


You will help to conceive of, build, and maintain features of the Clara platform. Some example core feature areas we work on today are: prediction-driven scheduling UI, calendar and preference modeling, load-balanced contractor task distribution, and advanced payment allocation algorithms.

You will also play a key part in product design and development. At our size, engineers are often responsible for features end-to-end, collaborating closely with and balancing the needs of operations, design, and machine learning.

In this role, you will provide an active voice in the organization for standardizing front-end tooling, design patterns, and processes. We're looking for someone pragmatic but opinionated.

You should:

  • Have a knack for visual design and user experience; you will advocate for the customer to ensure great product interactions
  • Love details and the nitty-gritty of front-end development
  • Have experience working across the stack (our backend is in Python)
  • Enjoy staying up to date on the ever changing world of front end development patterns and tooling. We aim to build good products quickly in this landscape.

We're looking for engineers that are customer focused, collaborative, and excited to pursue difficult, often loosely defined problems.

Nice to have(s):

  • Experience with React and Flux.
  • Experience with Python, Flask, SQLAlchemy, and AWS. 

Optionally with your resume:

  • A cover letter explaining why you think you are a great match for Clara.
  • A link to a Github repo of yours.
  • Tell us about one of your interesting projects!
