Mason is the fastest way to take smart devices from idea to end user. Whether building a single-use device from scratch or scaling a line of smart products, with Mason it’s 20x faster and 10x less costly to build, deploy and scale. Digital transformation is a modern requirement but operating a hardware-dependent initiative is hard – thousands of hours and millions of dollars are at stake.

The Mason Smart Device Platform is the only fully managed infrastructure for developing and delivering dedicated devices. It offers flexible usage-based pricing for fleets of devices and manages the underlying complexity of all associated backend services, making software delivery on a smart product line—whether it’s a tablet, wearable or new form factor—as simple as delivering software in the cloud. This frees innovators to focus on what matters: application development, feature specification and UX. Granular access to add, remove or lock down capabilities makes it possible for highly customized products to be built as envisioned.

Mason offloads hardware investment risks and logistics, including inventory procurement, warehousing and supply chain management. With options like zero-touch provisioning, devices can work perfectly out of the box without end user intervention. Remote fleet management, troubleshooting and automated software updates by Mason ensure security and positive end user experiences. Organizations of all sizes rely on Mason to bring innovations and hundreds of use cases to market without reinventing the wheel. Smarter from start to finish with Mason.™

Engineering at Mason

Engineering team and processes

Engineering process: We use a lightweight Kanban-style process and release frequently (OS updates, front end, and services). Independent components rev out of band as needed, and we're working towards the dream of continuous deployment.

Standards: We use standards where they make sense. We write one-pagers for significant features or changes, have them peer-reviewed, and own testing, implementation, peer code review, and deployment.

Teamwork and fun: Engineers are encouraged to learn and experiment with new technologies, and teach others. We demo our work regularly at the all-company meeting Show and tell. We hold quarterly hackathons and encourage everyone to get their hands dirty — at least a couple of our current roadmap items are straight from one such event!

Technical Challenges

Our product is mobile infrastructure-as-a-service. Consequently, from services to storage infrastructure to logistics to Android-compatible devices to firmware engineering our projects involve a variety of interesting and challenging work. A lot of our focus is around automation. Below is a selection of some of the fun challenges we work on (many are yet to be built!).

Mason OS and Core Apps: * Management and unification of multiple OS source trees and integrating our core feature set across all of them * Integration of a build pipeline in our production workflow * On device apps/services for remote control, log retrieval, push notifications, secure data storage, certificates, etc.

Developer (customer) productivity: * Command line interface to a variety of platform functionality * Automated generation of documentation of hundreds of feature points within a large, evolving source tree * Zero touch provisioning — automation of the registration and customer-specific setup of devices at scale (e.g. turn on a device and watch it automatically transform into a custom bar code scanner device)

Backend, Devops and Scaling: * Firmware and app update services to handle a projected half a million devices over the next 2-3 years * Services to handle metrics, analytics, license management, audit events, etc. * Migration to containerization of all of our backend services

Frontend: * ReactJS dashboard to list and map large numbers of devices * Searching, tagging, drag and drop deployment support of devices * Device fulfilment dynamic charting * Tracking and visualizing live devices in the field

Come build, influence, innovate and grow with us!

Projects you might work on
  • Controller: This is one of our core product offerings. We build OS services, apps, back end services, web dashboards, command line tools and scale infrastructure to support firmware and application updates over the air for a projected half million devices over the next couple of years. It is also about enabling customers to have complete control and visibility into their device fleets out in the field via a full-featured API and features such as remote control, optional device geo-tracking, device log extraction, audit logs, and a variety of others!

  • Creator: This is a future-looking product that is all about speeding up the process of designing a custom device and accessories without dealing with manual/inefficient processes.

  • Commerce: This is a future-looking product which is around speeding up and automating the whole device ordering, fulfillment and logistics part of our business. Imagine clicking a few buttons and ordering scores of devices to add to your fleet and managing their lifecycle from ordering, shipment tracking, and delivery all the way through RMA, support and device upgrades.

Working at Mason

Masons are a diverse, inclusive group brought together by our shared values that guide us in how we work together and show up for each other. Check out our values and see if they resonate:

Diversity and Inclusion

Belonging, psychological safety, and inclusivity unlock a Mason’s full potential. We don’t want Masons to quietly assimilate into a dominant culture and sacrifice a piece of themselves. We want our team members to be seen, validated, and welcomed. Although we still have a long way to go, when we engage with our team members and listen to their unique stories, we benefit.

To keep our values aligned with our behavior and organizational structure we aim to eliminate barriers, then strategically create and reinforce positive practices to produce equitable opportunities and empower every Mason, especially those from underrepresented communities. We cannot possibly build smart and sustainable products without diverse and inclusive teams.

Connect with our team during your hiring process

As part of our commitment to an inclusive workplace, we are happy to offer prospective engineers the chance to connect with our engineering employees who come from underrepresented backgrounds. It’s a way to get a better sense of our team and what it might be like to work with us.
