Resin.io provides a software platform that helps developers build, deploy and manage code on connected devices. We brought Docker to embedded GNU/Linux devices in 2013 and have been building our IoT toolkit ever since. We also maintain a variety of successful open source projects including Etcher, Balena, and resinOS, and made contributions to high-exposure projects such as Docker, Electron, and AppImage.
Our technology is open, standards-based, and proven in production across a wide range of scenarios from drones, 3D printers, point-of-sale devices, tidal turbines, skyscrapers and more. Our investors include DFJ, Aspect Ventures, GE, and Ericsson.
Resin is a highly distributed, remote-friendly company with a pretty much flat hierarchy. Our organization is adaptive, getting feedback signals from our users and systems. Right now we organize ourselves by projects, which allow us to build complex features and solve big problems, while staying mutable. As a distributed group, we rely on clear communication and the rule of "assume positive intent" to help us work together across time zones, cultures and first languages. Our base of operations is nominally London, though really we are living all over the world: from Barcelona to Bulgaria, Argentina to Vietnam, and many more.
We maintain a service infrastructure for IoT devices, and this is where we have quite a bit of our engineering talent. You will be actively working on one or more of these core components, fixing bugs, solving complex technical problems, and implementing user-facing features across the resin.io stack. While resin.io focuses on IoT, the majority of our engineers don't require embedded programming expertise.
People who are successful engineers are well-rounded generalists and great communicators. They are eager to take responsibility for a project, and are able to make good decisions about the project because they have the context of what's important.
We don't require engineers to be already familiar with the technologies we use. We are happy to invest in people that showcase a strong understanding of the challenges of building secure distributed systems.

On the Nomad team, we develop tools for service deployment and batch job scheduling. Our customers place a high level of trust in us, relying on our tools to operate their own infrastructure and software effectively, and so we care deeply about reliability and performance.
This particular position is unique in that in addition to general Nomad backend engineering duties, this person will be the sole internal owner of the Nomad integration for Spark. We anticipate that work taking approximately 15-20% of this person’s time, and the rest of the time will be spent working on the overall Nomad roadmap along with the rest of the Nomad team. While we strive to hire at a variety of experience levels, this particular opening is not well-suited for recent graduates due to the level of independent ownership we expect for the integration for Spark. You will have the support of a Product and Engineering Manager in prioritizing and delivering work for the integration, but minimal fine-grained oversight from other Nomad Engineers. You will, however, benefit from direct interactions with users of the tool! This is an excellent technical leadership opportunity for someone with the capacity to operate well at this level of independence.
At HashiCorp, we value top-notch collaboration and communication skills, both among internal teams and in how we interact with our users. We take care to balance and be responsive to the needs of our open source community as well as our enterprise level customers.
Engineering at HashiCorp is largely a remote team. While prior experience working remotely isn't required, we are looking for team members who perform well given a high level of independence and autonomy.
In your cover letter, please describe why you're interested in working at HashiCorp, and what draws you to this role in particular! Since this is a unique role on the team, we require a cover letter for your application to be considered complete.
At HashiCorp, we are committed to hiring and cultivating a diverse team. If you are on the fence about whether you meet our requirements, please apply anyway!
