About The Opportunity

We’re seeking a skilled and versatile Fullstack Software Engineer Contractor for a 6-month engagement to support our product engineering team via staff augmentation.

You’ll play a hands-on role in delivering high-impact features that align with our roadmap—especially those focused on Pricing & Packaging experimentation and billing platform enhancements.

This role is ideal for engineers who are self-directed, collaborative, and comfortable working across the stack, particularly in PHP and Vue environments.

You'll be contributing to a platform actively undergoing modernization, so familiarity with both legacy support and new feature development is essential.

Responsibilities

Collaborate with product managers, designers, and engineers to deliver full-stack features from concept to production.
Design, build, and optimize Pricing & Packaging experiments that drive user engagement, monetization, and conversion.
Integrate and extend Stripe for billing, subscription, and payment workflows.
Contribute to and modernize systems built in PHP (Laravel) and Vue (Vuetify/Nuxt).
Build and maintain new services and components using React and Go.
Deploy, scale, and monitor services using AWS infrastructure.
Participate in agile ceremonies and contribute to sprint planning, estimation, and retrospectives.
Take full ownership of deliverables with a focus on performance, usability, and maintainability.

Required Qualifications

Strong experience with PHP, ideally using Laravel, including legacy support and modernization.
Proficiency with Vue.js, especially frameworks like Vuetify and Nuxt.
Hands-on experience with AWS (Lambda, ECS, S3, etc.).
Demonstrated integration experience with Stripe for payment flows and subscription management.
Experience building frontend features using React.
Backend development experience in Go (Golang).
Experience implementing Pricing & Packaging experiments with feature flagging, A/B testing, and iterative development.
Hands-on experience with Optimizely, including experiment setup, analysis, and integration workflows.

Nice To Have Skills

Familiarity with other experimentation platforms (e.g., LaunchDarkly).
Exposure to observability tools such as Datadog or CloudWatch.
Prior experience modernizing monolithic or legacy systems into more modular or service-oriented architectures.
