AI-Native Full Stack Product Engineer

Description

Lighthouse Software Group is an operating group of Valsoft Corporation, a global acquirer and operator of vertical market software businesses. Valsoft acquires and builds mission-critical software companies serving highly specialized industries and holds them for the long term.

With 150+ companies and 4,000+ employees across 20+ countries, Valsoft’s decentralized model empowers businesses to operate independently while benefiting from operational best practices and long-term capital.

Lighthouse is responsible for sourcing, acquiring, and operating vertical market software companies globally. As we continue to grow, we are seeking driven individuals who want to join the team!

About the Role

We are looking for an AI-native full stack engineer to join one of the leading software companies within our portfolio.

Our platform powers mission-critical workflows for organizations that depend on it every day, and we are actively expanding it through AI capabilities and entirely new software products.

This role is designed for engineers early in their careers who want to build a lot, learn quickly, and take real ownership. You will work across both an established production platform and new AI-driven products.

We are especially interested in people who see themselves as builders. The best candidates are curious, ambitious, and constantly experimenting with new tools. They build side projects, explore AI models, and look for opportunities to improve systems rather than waiting for instructions.

You will work closely with a senior engineer who has built and scaled production systems and will provide direct mentorship as you grow. As the engineering team expands, there is also a clear leadership runway for someone who wants to take increasing ownership and eventually help lead the team.

This is a profitable, stable company with real customers and real infrastructure. The company operates within Lighthouse Software Group, part of Valsoft, a global group of vertical market software businesses with more than 130 companies and 4,000 employees across 20+ countries.

Roles & Responsibilities

You will work across three main areas of the product.

• Core Platform Development (Approximately 25%)
• Work within our existing production platform built primarily with PHP, Zend Framework, and JavaScript.
• Responsibilities include:
• Building and enhancing features within the existing platform
• Debugging and resolving production issues
• Refactoring legacy code to improve maintainability
• Improving reliability, performance, and system quality

• AI Feature Integration (Approximately 25%)
• Help bring AI capabilities directly into the platform.
• Responsibilities include:
• Integrating LLM and AI APIs into product workflows
• Building AI-powered tools and automation inside the platform
• Identifying opportunities where AI can improve user workflows
• Ensuring AI features are reliable and production-ready
• Using AI development tools as part of your workflow is expected.

• New Product Development (Approximately 50%)
• Build new software products that expand the platform.
• Responsibilities include:
• Designing and developing new applications and product modules
• Building production-ready systems rather than simple prototypes
• Working across the product lifecycle from concept to deployment
• Contributing ideas that shape future product direction
• Much of this work will involve modern frontend development using React and related technologies.

Required Experience

• 2 to 4 years of professional software development experience
• Experience building or contributing to production applications
• Comfort working across frontend and backend development
• Experience using or experimenting with AI APIs, LLMs, or AI development tools
• Familiarity with modern development workflows and cloud-based tooling
• We are particularly interested in candidates who demonstrate a builder mindset. Examples include side projects, experimentation with AI tools, open source work, or personal technical projects.
