Overview

The AppLogic Team builds core software for the Graykey platform, which Law Enforcement and Government Agencies use to extract data from mobile devices. The AppLogic UI is where examiners do that work.

We're a small, senior, hands-on team, and this role leads frontend for it. You'll work alongside our UX Design Team, turn their work into an interface that's fast, reliable, and easy to build on, and set the structure and conventions the rest of the team follows.

The UI is a mature, server-rendered application built with plain JavaScript and Jinja templates, with CI/CD and unit tests in place. Examiners use it every day, so the job is steady improvement in place: better structure, better performance, and better data, one change at a time. If you're looking to start fresh on a new framework, this probably isn't the right fit.

NOTE: Candidate must reside in Canada.

What You'll Do

• Own the architecture of the AppLogic web UI and evolve it incrementally while it stays in daily use.
• Set frontend conventions for the team (structure, naming, testing, review) and raise the bar through code review and pairing.
• Keep the UI fast and responsive as the product grows.
• Own product analytics instrumentation so the data is consistent and useful to product management.
• Work with UX design to turn designs into production UI, and with product and engineering teams across the company.
• Treat frontend security as part of the job.

What We're Looking For

Frontend depth.

This is the core of the role:

• Strong JavaScript, HTML, and CSS, and comfortable building without a framework. That means a real understanding of the browser itself: the DOM, the event loop, rendering, and the network
• Experience improving a mature production frontend incrementally, without stopping to rewrite it
• Frontend architecture: state management, component design, and module boundaries
• Performance work: profiling load time and runtime behavior, and fixing what you find
• Frontend testing at the unit, integration, and end-to-end levels, with good judgment about which tests are worth writing
• Real-time UI patterns such as WebSockets or server-sent events
• Web security fundamentals, including XSS prevention and safe handling of untrusted input

Python.

The templates live in our Python application, so you'll be in Python code regularly. You should be comfortable reading, changing, and testing production Python, including Jinja (or similar) templates and the endpoints the UI depends on.

Instrumentation.

You've designed product analytics event schemas that product managers could use, and you understand what the frontend has to get right for that data to be trustworthy.

Constrained environments.

Our software runs on custom hardware installed on-premises at customer sites, often on locked-down networks. The UI can't count on a fast or open internet connection, so you should be comfortable building for that: keeping pages light, not depending on outside resources to load or work, and handling slow or missing connections gracefully.

General

• 6+ years of professional engineering experience, most of it on production web frontends.
• A track record of setting frontend direction for a team: choosing patterns, writing them down, and getting others to adopt them.
• Experience working directly with product managers on scope, priorities, and trade-offs.
• Str
