Senior Quality Engineer

About LawnStarter

LawnStarter is the nation's leading on-demand marketplace for lawn care and outdoor services, with over $100M in annual bookings. We're expanding beyond lawn care to become the one-stop shop for all home services, operating across three brands (LawnStarter, Lawn Love, Home Gnome) on a single shared platform.

About Engineering at LawnStarter

We've spent the last two years rebuilding the platform from the ground up: new customer app, new Pro onboarding, job distribution engine, and data infrastructure. The foundation is solid. Now we're moving into expanded service verticals, dynamic pricing, and AI-powered features at scale. Quality needs to keep up.

Our stack is PHP (Laravel) and React/React Native, with Cypress as our primary test framework. We actively use Claude Code as part of our engineering workflow, not as an experiment, but as a core part of how we work.

The Role

As we scale into new service verticals and grow the engineering team, quality can't be reactive. This role exists to make quality proactive: owning the automation coverage, shaping the bug process, and partnering closely with Product, Design, and the Data team to catch problems before they reach customers.

About the Role

Zyte is looking for a Quality Engineer to join our unified Quality Engineering function. This is an automation-first, AI-native role embedded directly within our engineering squads.

You will be responsible for designing risk-based test strategies, rapidly converting them into automated checks using AI-assisted development workflows, and continuously improving the quality, speed, and reliability of software delivery. Quality at Zyte is not a gatekeeping function. It is an engineering discipline focused on preventing defects, accelerating delivery, and increasing confidence in every release.

AI coding agents are a core part of how we work. You will be expected to use Claude Code or equivalent AI-assisted development environments as your primary development partner for generating, reviewing, debugging, refactoring, and maintaining automation code.

Senior Frontend Engineer - High-Performance Financial Platform

Location: New York, San Francisco (Office)

Compensation: $185K - $300K

We are hiring on behalf of our client who are building a revolutionary Multi-Asset Margin solution for one of the fastest-growing ecosystems in decentralized finance. Currently, the crypto derivatives sector generates $20B–$30B in annual revenue, and multi-asset margin accounts for over 86% of all trading activity. Their mission is to bridge the gap between diverse collateral types and high-performance trading.

Their platform allows users to post variable forms of collateral without needing to sell their assets for stablecoins. By building sophisticated blockchain-integrated systems "under the hood," they extend liquidity to the venues of their users' choice, bringing the market to them rather than forcing them to navigate multiple fragmented platforms.

As a member of their Product & Platform team, you will build and maintain the applications that power these services. You will collaborate closely with designers, backend engineers, and product managers to deliver responsive, high-performance user interfaces that define the future of DeFi trading.

The Frontend Engineer will be responsible for the full lifecycle of application development, focusing on performance, user experience, and real-time data visualization.
