Software Engineer at Mixmax

San Francisco, CA, United States of America

Posted on Feb 26 2018 (about 3 years ago)


  1. You're working with us full-time (40hrs/week)
  2. You can overlap with San Francisco 10am - 7pm time by at least 4 hours, 4 days a week.
  3. You've worked with another company full-time remote before
  4. We also strongly prefer that you've made open source contributions before

Mixmax is the future of email and external communications. Just like you use Slack to talk within your team, you use Mixmax to talk to people outside of your team. We primarily help sales and recruiting teams achieve more by automating their most common work ows and integrating with their existing toolchain - Gmail, Inbox, Salesforce, Slack, text messaging and more. At Mixmax, our mission is to do the impossible with email: to make it as rich, interactive, and developer-friendly as the web.

What will I be working on?

As a full-stack engineer, you’ll be working with us in all aspects of the product, from its core infrastructure to its custom front-end. This includes architecting systems to integrate with external services, building a full-featured web editor, and choreographing email systems and protocols. We’ll leave it largely up to you to evolve the stack as you see fit. We eagerly participate in open source development and will encourage you to do the same.


  • Experience in Javascript (Node.js, front-end frameworks), ElasticSearch and Mongo
  • Significant experience building web applications that have shipped
  • You enjoy writing well-tested, well-organized code

What you might work on:

  • Scale our backend service to send many millions of messages a day
  • Architect the next generation of the Mixmax API: supporting rich communications apps that work on a broad spectrum of clients.
  • Maintain an elastic distributed infrastructure built on top of AWS
  • Build large scale data processing pipelines for indexing content
  • Continuously find opportunities to improve performance, and increase reliability & quality

Current stack: NodeJS, Go, React, Mongo, ElasticSearch, Redis, Electron, AWS.

Check out our engineering blog and our commitment to open source (Github, Open Collective).

What are you looking for in a team member?

Your specialization is less important than your ability to learn fast and adapt to shifting technologies. We’re especially fond of people who:

  • Focus on project goals, not just writing code.
  • Iterate until customers love what you’ve built, and pay for it.
  • Have a hacker mindset and master the fine art of balancing time, features, and quality of code. You know when to unit test and when to “just ship it”.
  • Strive to grow personally and professionally, beyond just expanding technical abilities.
  • Love to experiment with new technology and share knowledge with the team.
  • Represent the team and product at conferences.

If you are a member of an under-represented group in technology, we strongly encourage you to apply.

What’s it like to work at Mixmax?

We’re a driven, passionate, responsible group who values personal and professional growth equally. We take care of ourselves, our families, our customers and one another. We believe in sustainable and diverse approaches to work and life, because optimizing for the long-term is the best path to success. As a team, we built multi-million dollar products with this balance in mind.

As a founding team member, you’ll wear multiple hats, embrace ambiguity, and take charge leading complex projects. You’ll have the support of an experienced team who’ve built multi-million dollar products and services. This is exceptionally challenging work, but will be the most meaningful and rewarding of your career.
