Joby Aviation | Bay Area Preferred or Remote (US) | Full Time | https://joby.aero

Located in Northern California, the team at Joby Aviation is driven by our goal of creating an affordable, all-electric air transportation system. Imagine a piloted air taxi that takes off vertically, then quietly carries you and your fellow passengers over the congested city streets below, enabling you to spend more time with the people and places that matter most. Since 2009, our team has worked steadily to make this dream a reality. We’ve designed and tested many generations of prototype aircraft capable of serving in a network of electric air taxis. We’re looking for talented, committed individuals to join our team as we push onwards toward certifying the Joby aircraft with the Federal Aviation Administration, scaling our manufacturing, and preparing to launch commercial service in 2025.

The Air Taxi team is growing and we need more engineers to help build our platform and apps to support day to day operations and rider engagement. Why we like working here:

- Software engineering team is hybrid between the Bay Area and remote. We have an onsite for a week every 3 months where we gather to plan and hang out.

- We're full of aviation enthusiasts so if you're a pilot or want to be this is the place to be.

- The problems we're solving are difficult and fun.

Notable Roles:

- Senior Full Stack Software Engineer: https://careers-jobyaviation.icims.com/jobs/2983/senior-full...

- Senior Backend Software Engineer: https://careers-jobyaviation.icims.com/jobs/2980/senior-back...

Automattic | Remote | Full-time | Senior Systems Engineer (Systems Wrangler) | $110-$210k+

We're looking for the world's best systems engineers to help build and maintain the infrastructure that supports over a billion people each month across our entire line of products and services such as WordPress.com, WooCommerce, WordPress VIP, Jetpack, Tumblr, Texts.com, Day One, Pocket Casts and many more.

Here are the goals of the team that you would join:

* Remove as much friction as possible between Automattic developers and their goal of shipping software. When there are questions, we can provide answers in a matter of minutes, sometimes seconds.

* Make Automattic services as fast as possible through optimization of server-side and client-side interactions.

* Maximize the availability and uptime of all services through proactive planning, sound architectural decisions, and rapid response to failures.

* Ensure our services are safe and secure for both our users and employees through a combination of proactive monitoring and enforcement, real-time response, and ensuring data integrity/backups to allow recovery from disasters.

* Share our code, experience, and knowledge, both internally and externally whenever possible. Internally, this is usually accomplished via Slack, IRC, internal blogs, and code reviews. Externally, we try to blog publicly, speak at conferences, contribute to open source software, and release our own software under an open source license.

* Control costs through careful selection of technology partners and prudent negotiations of pricing and contracts. We work with 3rd party services where it makes sense, but always look at the big picture and value control and performance over cost.
