Position Overview

We are looking for a Lead / Principal Backend Engineer to help build the next generation of our smart building products. This is an opportunity to make difference by developing products that make offices, hospitals, factories and warehouse into energy efficient, interactive and efficient spaces in which to work. Come join our startup culture and participate firsthand in designing the future of workspaces.

Having successfully deployed the first generation of our products, we are putting together teams to build the next generation to address a range of IT, OT, and IoT use cases (including real-time location, wayfinding, people counting, room booking, access control, and visitor management); and are exploring ways to leverage machine learning across our product. Simultaneously, we are aggressively growing our user base, with some of our largest-ever deployments currently in flight.

We value clean architecture and modern approaches to software development and testing. Our products consist of cloud-based micro-services and modern web and mobile applications. You will work closely with a tight, agile team that ships features continuously, and you will be able to see the impact of your work on real customers.

As a Principal Engineer, you’ll be working across teams to solve challenges around building scalable, extensible applications on both web and mobile. This role will have many of the characteristics of a technical lead, working closely alongside our back-end and platform teams to shape our UI strategy. You'll be part of the brain-trust that our engineering and product leadership will rely on to advise us on what's possible, what's sensible, and what's simple. In order to do that, you'll need to have technical depth; systems thinking; and communication skills to evaluate trade-offs around performance, cost, reliability, and scale. This is the ideal role for someone who's ready to move their career to the next level in terms of technical influence and scope of impact. Join us in Transforming the Everyday!

What will you do?

  • First and foremost, you love building great software that make your customers happy. You love elegant, well-structured user interfaces that are wonderful to use. Your teams write code that is comprehensible, well-structured, highly performant, and you are equally comfortable in front of the computer cranking out code on your own or mentoring your team to develop great code.
  • You are curious and passionate about knowing “why”, whether it is why a use case is important for a customer, or why something strange happens one time in a hundred tries.
  • You love both learning and teaching. In this role, you will be interfacing with design, front-end, back-end, platforms, analytics, as well as our PM and QA teams; towards that end, you enjoy working across teams to solve hard problems.
  • Agile development is second nature. Not only will you be expected to participate in daily scrums, sprint planning, and retros; you'll be expected to help improve our ceremonies.
  • You strive for quality, and are obsessed with unit tests, automation, and squashing any bugs that sneak through. But it's more than that: you'll use our product, realize "hey! that's not what I expected!" and figure out how to make it better for everyone.

What will you need to succeed?

  • Deep knowledge of cloud technologies (especially native cloud with AWS)
  • Deep knowledge of modern web development with preferred Vue or React frameworks
  • Experience in delivering mobile applications on both Android and iOS
  • Good experience with multiple modern programming languages
  • You're obsessed with performance, and have experience with instrumentation and monitoring services to ensure the application is behaving as expected
  • You have a basic knowledge of computer science fundamentals, including data structures, algorithms, and object-oriented design
  • 10+ years of industry experience developing commercial user-facing applications
    • Experience in fully automated CI/CD concerns (IaC, quality, testing, etc)
    • Understanding of micro-service development
    • Understanding of web service development
    • Understanding of various API protocols (REST, GraphQL, gRPC, etc)
    • Understanding of serverless development
  • Proactive business skills and strong collaborative skills are required.
    • Self-Directed, High Energy
    • Demonstrated leadership skills; ability to work independently with minimal supervision as part of a globally distributed virtual team
    • Proven ability to collaborate effectively across disciplines, product lines, roles and geographical and time zone boundaries
    • Excellent oral/written communication & listening skills will be necessary to present information, analysis & recommendations to all levels of employees, including management, and customers.
    • High degree of organization to manage & maintain project plans, road maps & provide accurate updates as part of the review cycle.

  • Experience with Hybrid App development
  • Experience with Flutter/Dart
  • Experience mapping technologies (GIS, MapBox, Location Technologies, etc)
  • Experience working with event driven and/or event sourcing techniques

Technologies We Use: Java, Quarkus, Python, FastAPI/Flask/SQLAlchemy, NodeJS, Vue3JS, JavaScript, TypeScript, Flutter, GraphQL, All things AWS, Terraform
