Senior Software Engineer

About Perry Weather

Thousands of organizations trust our fast growing weather safety platform across school districts, cities, universities, golf courses, construction, and other industries. Our software and connected hardware enable rapid decision-making for organizations facing the threat of weather disruption: How long can I wait to pull players off the field for the nearby storm? How should I modify activities to prevent heat stress injuries? When can operations safely resume on the tarmac? How can I be sure my staff adheres to a weather policy?

The Role

As a senior software engineer, you will join our small but growing team of software engineers. You’ll work across the board, from our React web dashboard and React Native mobile app to the .NET services and real-time weather processing and alerting infrastructure behind them. You’ll learn how our software interacts with our proprietary hardware, and you’ll drive improvements to reliability and efficiency with every deployment. We’re looking for someone who is hungry, scrappy, and humble and who is energized by the fact that our weather safety solution protects thousands of lives every day across North America.

This is a full-stack role in the widest sense. We want an engineer who can own a feature from the interface a customer touches down to the device in the field, and who is comfortable moving into an unfamiliar part of the system, building an accurate picture of how it works, and changing it safely. Nobody here is an expert in all of it.

We also expect you to build with AI coding agents as part of your daily work.

We aren’t constrained by a certain set of technologies, languages, or frameworks. We pick the right technologies for each job, and as a software engineer on our team, you will have tremendous influence in determining those technologies and how we build our systems as we continue to scale. That said, we care as much about your hunger and ability to learn quickly as about what you already know.

What you’ll be doing

• Work across our React web dashboard, React Native mobile app, and the .NET services behind them

• Work with weather APIs and real-time weather and lightning data (we process hundreds of thousands of lightning strikes every day across North America)

• Build and maintain back-end services in .NET for Linux environments

• Work with Docker containers in a Kubernetes environment on Azure

• Work in a primarily Unix (macOS) environment targeting Linux

• Learn how our software interacts with our proprietary hardware, including the firmware running on our connected devices

• Coordinate deployments for large projects that touch many different systems

• Improve and innovate on existing infrastructure

• Use AI coding agents daily, and help set how the team works with them

REQUIREMENTS

• 7+ years shipping production software, with ownership on both sides of the same product: the interface customers touch and the data model underneath it

• A substantial React and TypeScript application you were responsible for: state management that held up as the app grew, a performance problem you diagnosed and fixed, and a component interface other engineers built against

• Backend depth in a statically typed language, including data modeling, transaction boundaries, and API design that survives a growing set of clients. We use C# and .NET; comparable depth in Java, Go, or Kotlin transfers well

• A service you’ve operated in production. You deployed it, monitored it, debugged it under load, and redesigned part of it after a failure

• Real-time or event-driven systems experience, including backpressure, duplicate and out-of-order delivery, and upstream feeds that go quiet or start returning bad values

• Tests you would defend in review. You can explain why a particular test exists, which ones you removed, and how you’d verify a change in a codebase whose tests you don’t trust yet

• Fluency with AI-native engineering tools and agentic workflows (e.g., terminal-native coding agents, LLM-assisted code refactoring and generation) to multiply technical output and speed up development cycles

• The ability to review generated code for correctness. Agent output is usually idiomatic and well-formed even when the logic is wrong, so we need someone who checks it against the requirement. You should be able to explain any line you ship

A strong plus is experience with React Native, embedded or IoT work in C/C++ or on field-deployed hardware; geospatial and mapping work; weather or meteorological data; load and performance testing; and multi-tenant auth design.

You may be a fit for this role if:

• You have solid experience across a wide breadth of technologies, and you want to work across all of them rather than settle into one specialty

• You’ve been a part of a small, quickly growing software company

• You have a proven record of driving reliability and redundancy when working with large data sets and real-time notifications

• You don’t need much direction to complete high-quality projects from start to finish

• You hold a high bar for reliability. Our customers get alerts during severe weather, and a dropped notification can put someone at risk

BENEFITS & PERKS

• Casual work environment. We’re located in the vibrant Dallas Oak Lawn neighborhood. As a note, our team is in the office M–F!

• Comprehensive benefits. We offer competitive health insurance plans, 401(k) with employer matching, and a suite of voluntary benefits.

• Engaging culture. Monthly All-Hands, fun events like Office Olympics, lunch-and-learns, happy hours, and more.

• Grow with us. 80%+ annual growth for five straight years, and we still have a massive amount of work and opportunity ahead. Firmware, mobile, web, real-time pipelines, and infrastructure are all owned by one engineering team, so a single engineer can follow a problem from a sensor in a field to a customer’s screen.
