Compensation: $150K–$200K + equity

Our client is an innovative quantamental investment platform that empowers investors to build, share, and collaboratively execute sophisticated trading playbooks. The platform covers the entire investment lifecycle, including financial modeling, data visualization, quantitative strategy development, event-driven backtesting, and real-time dashboard monitoring. Designed to seamlessly convert strategic ideas into live execution parameters without requiring code, the platform fosters collaborative intelligence to turn individual research into a powerful, shared edge.

On behalf of this client, we are seeking a top-tier Quant Engineer to build and scale the core, production-grade trading engine that powers the platform's execution layer. This is a pure systems and infrastructure engineering position, rather than a quantitative strategy or research role. The successful candidate will focus heavily on infrastructure, architectural correctness, and high-level reliability across the end-to-end framework: from research and event-driven simulation to paper trading, live order routing, and real-time execution.

Key Responsibilities

We are looking for a Lead FullStack Engineer with strong backend expertise to help us build reliable, scalable, and high-quality products.

You will lead a small engineering team consisting of 3 engineers and 2 QA specialists. This is a hands-on role requiring deep involvement in architecture, complex technical challenges, and production development.

We expect you to actively leverage AI tools to improve engineering quality and development velocity.

Responsibilities

• Design and develop scalable backend services and APIs.
• Drive architecture decisions and ensure high engineering standards.
• Write production-ready code and actively use AI tools to accelerate development.
• Solve complex technical challenges and improve system reliability.
• Lead code reviews and maintain code quality across the team.
• Mentor engineers and help increase team productivity.
• Collaborate closely with Product, Design, and QA teams.
• Continuously improve development processes and engineering practices.

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.

We are looking for a FullStack Engineer with a strong backend focus to help build and scale Enterprise products.

You will work closely with Product and Engineering teams to develop partner-facing experiences, widgets, and internal applications.

Responsibilities

• Build and maintain frontend applications, widgets, partner portals, and landing pages.
• Design and implement backend services and APIs.
• Prototype new partner integrations and B2B solutions.
• Work closely with Product Managers and Designers from requirements to production.
• Own features end-to-end, including deployment and support.
• Participate in code reviews and architecture discussions.
• Actively leverage AI tools to accelerate development and increase productivity.

Requirements

Backend

• Commercial experience with Node.js and TypeScript.
• Experience building and maintaining REST APIs.
• Good understanding of PostgreSQL and Redis.
• Understanding of asynchronous patterns and message queues.
• Familiarity with JWT and OAuth2.
