Senior Backend Engineer

At Density, we build one of the most advanced people sensing systems in the world. The product and infrastructure is nuanced and one-of-a-kind. Building this product for scale has been an exercise in patience, creativity, remarkable engineering, laser physics, global logistics, and grit. The team is thoughtful, driven, and world-class. 

Importance of Engineering 

We build systems that are real-time, accurate, and anonymous by design. Our systems help today’s largest companies understand how their buildings get used. We have counted hundreds of millions of people. 

Counting people in “real-time” is unique and particularly hard to achieve. It allows a user to walk into a room, beneath our sensor, and see the room’s occupancy increment 700ms later.  

Today alone, Density will ingest over 1m events. In the coming year, our sensor network is on track to grow ten-fold. The overall system load is exploding. Maintaining our low latency standards requires an increasingly thoughtful system. 

We’re architecting infrastructure where annual, unscheduled downtime is measured in minutes. We’re building intelligent redundancies so missed events are an oddity. We’re constructing an exceptional engineering team to support always-on, intelligible analytics generated on the fly.  

Real-time can solve one of the world’s most fundamental problems -- how do humans use all this space? Last week we launched Safe by Density to help organizations safely return to the workplace. This product, a singular example, would not have been possible without real time data.  

This is a large, nuanced, deeply technical problem. We need your help solving it.

Full Stack Engineer
Density  
react-js api python full stack javascript html Apr 04

When someone installs Density in a location, they get access to real time, accurate people count. The experience is magical to a customer, but the process involved in accomplishing it is complex. Density has counted 13 million humans, and that number is growing exponentially. We are seeking a talented backend engineer to help architect a suite of web-based products to transform that data into insight.

The software systems that support Density are foundational: our customer facing APIs and applications, our data ingestion pipeline, the systems that manage and orchestrate our fleet of devices, and the internal tools that keep our organization running smoothly. We put a high value on the infrastructure that supports our systems, and love approaching problems through research, prototyping, and experimentation. We are not afraid to embrace new technologies, but are mindful in what we choose.  

As an organization, we understand the importance of design, focusing on fundamental problems, and decentralizing decision making. As an engineering team, we design, build, and test with simplicity and scalability in mind. As individuals, we take ownership in our work and decisions. We’re looking for someone with a deep understanding of the web who shares these ideals.

The successful full-stack engineer will be applied to a wide variety of systems that constitute the Density platform. The Density platform is large, and your breadth of engineering knowledge will be put to the test.

A few key pieces of our system include:

  • APIs and data-pipelines that process millions of events
  • Mobile applications that help customers get their sensors online
  • Engaging web applications that help visualize people-count analytics
  • Notification systems that act on a set of triggers
  • Internal tooling that we use for our deep-learning models

This position reports to Density's Director of Software Engineering.

What you'll work on

  • Lead development on internal and customer facing projects utilizing Javascript, React, Python, Django, Postgres, Redis, Kafka, AWS and other technologies
  • Build APIs and data delivery mechanisms for applications such as web dashboards, alerting & health systems, mobile applications, and third party integrations
  • React to customer needs and feedback through tight-looped, iterative development
  • Contribute to open source initiatives
  • Document and teach best practices across our stack

What we're looking for

  • 2+ years industry experience building backend and front-end applications
  • Experience with relational and non-relational datastores
  • Experience with building applications using ES6, React, and Redux
  • Strong background in HTML and CSS
  • Experience with data-centric applications, including analytics pipelines, report generation systems, and alerting & health systems
  • Experience testing full stack web applications using frameworks and tools
  • Strong writing skills, with experience crafting clear and concise documentation
  • A motivation for constant learning

Icing on the cake

  • Experience with statistical analysis and trend data modeling
  • Experience with container orchestration technology kubernetes or ideally Nomad
  • A deep appreciation for design
  • A strange obsession with counting people (or what you can do with the resultant data)

While we have offices in Syracuse (NY), San Francisco, and NYC, we embrace and have built a culture around remote work.

Data Engineer

To our future Data Engineer

At Density, we build one of the most advanced people sensing systems in the world. The product and infrastructure is nuanced and one-of-a-kind. Building this product for scale has been an exercise in patience, creativity, remarkable engineering, laser physics, global logistics, and grit. The team is thoughtful, driven, and world-class.

Why this is an important role

Last week our deployed DPUs detected a million humans walking through doors. A number that increases every week.

As engineers, we think it's pretty cool to be capturing events at this volume. Especially when it's done anonymously, accurately, and in real-time. Our customers, however, are interested in what happens after these events enter our system.

Density is deployed globally, servicing a variety of use cases, by some of the largest companies in the world. Here are just a few examples. A leading cloud storage company is using Density to strengthen their physical security by detecting unauthorized access. A marquee hotel brand is using Density to measure lounge occupancy and dynamically deliver world-class service. An international telecom is using Density to better design and optimize their real estate portfolio.

These use cases may seem disparate, but a common thread holds them together. They all share the need for real-time and ongoing data analysis. And that's where you come in.

Our systems must efficiently and reliably:

- Update current counts and analytics whenever a relevant event occurs, for every impacted space,
- Publish the information to low-latency receivers via webhooks and websockets,
- Alert and notify as appropriate through SMS, email, and push notifications, and
- Aggregate events into analytics used for dashboards, forecasts, and fleet management.

Turning millions of events into actionable insight is a nuanced dance. Are you up for the job?

What you'll work on

  • Scale event ingestion pipelines requiring high availability and real-time data processing/delivery.
  • Store, optimize, and deliver analytical data via a RESTful API.
  • Backend development on internal and customer facing projects, utilizing Python, Django, and NodeJS.
  • Refine APIs and data delivery mechanisms for applications such as web dashboards, alerting & health systems, mobile applications, and third party integrations
  • Work closely with DevOps to monitor inefficiencies and improve infrastructure
  • React to customer needs and feedback through tight-looped, iterative development
  • Contribute to open source initiatives
  • Document and teach best practices across our stack

What we're looking for

  • 5+ years industry experience building and scaling web applications and APIs
  • Deep experience with stream processing systems (i.e. Kafka)
  • Experience writing ETL pipelines on a cloud infrastructure (AWS)
  • Deep experience with Python, Django / DRF, and Postgres
  • Experience building data-centric applications, including analytics pipelines, report generation systems, and alerting & health systems
  • An understanding and appreciation for application performance monitoring and profiling tools
  • A desire to define, document, and teach web engineering standards
  • Strong writing skills, especially with crafting clear and concise documentation
  • A motivation for constant learning
