About Frontier

Frontier is a subsidiary of Fresh Prints. Fresh Prints is a New York based, fast-growing, fully-remote, 150-person company that has most of our team in India and Philippines. A few years ago Fresh Prints started helping other fast-growing companies build their teams. We got so good at it that we decided to spin out a new company to focus exclusively on that and call it Frontier.

Here at Frontier, we help companies grow full-time, cross-functional teams abroad. We hire the smartest people, and we place them into the best companies. If you like one of the Frontier roles, and you apply, and you're accepted, we'll screen you with a couple of internal interviews, and will work on getting you an interview for a full-time job within the month. Think of us as your personal talent agent, and good luck with the application :)

About the client

Balto's mission is to power a new era of knowledge work in the contact center, and we're creating awesome technology to do just that. If you're excited by the opportunity to join a dynamic team initiating a technological revolution in Real-Time Guidance, Balto is for you.
More than just a company, Balto is a community. A community committed to empowering each of our members. This mission is at the heart of our organization. As a member of our Technical Success team, you'll act as the voice of the user, drive efficient implementation & product engagement from onboarding to continued adoption, and investigate solutions for complex technical issues.

Role Overview

We're looking for a Software Development Engineer in Test (SDET) who will own the reliability, coverage, and automation of Balto's testing ecosystem. This role is hands-on, bridging QA and engineering: you'll write automated tests, improve coverage, and help us continuously deliver high-quality code with confidence.

You'll work closely with product engineers to design testable systems, automate repetitive checks, and find ways to make our testing pipelines faster and more reliable — especially for our Electron desktop app and AI-powered features. Because of the close collaboration, you'll need to align your working hours with the US schedule.

What You'll Do

• Serve as first-line support for the engineering team, helping to triage and reproduce reported issues.
• Own bi-weekly regression testing, ensuring stable releases and reliable feature coverage.
• Identify gaps in our current test plans and write automation tests for missing smoke tests across features.
• Contribute to, and improve, our unit and integration test coverage, guided by tools like SonarQube.
• Design and implement test automation for our Electron app integrated with GitHub Actions.
• Collaborate with developers to ensure high-quality pull requests and resilient builds.
Work with AI-powered features to design test cases and prompts that validate intelligent behavior and performance.

What You Need to Know

• Strong programming skills in Python and JavaScript.
• Experience with Playwright for automated browser and UI testing.
• Solid understanding of Git and standard version control workflows.
• Familiarity with GitHub Actions for CI/CD automation.

Nice to Have

• Experience testing Electron applications.
• Understanding of AI models, especially around creating effective prompts and validating model behavior.

Who You Are

• A detail-oriented tester who loves building automation that prevents bugs
• Comfortable debugging across the stack and writing clean, maintainable code.
• Curious about AI and excited to work on products that integrate it.
• Pragmatic, organized, and collaborative. You are the person who makes shipping safe and predictable.
