About Phaselab
Phaselab is rebuilding the legacy eDiscovery industry from the ground up, empowering in-house legal teams with tools for document production that bypass the existing services-heavy approach. We're Seed stage but are already working with Fortune 500 companies and are scaling rapidly.
The Role
We’re looking for a Product Engineer to help us build and scale our core product. You’ll work closely with the CTO, AI Engineer, and Head of Product to ship impactful features and improve performance across the stack. This is a high-ownership, high-impact role where you’ll directly shape the future of Phaselab’s technology.

Get onboarded, set up your dev environment, and dive into our systems.
Ship a small update or bug fix to get familiar with the codebase.
Use the product to understand how it works and identify areas for improvement.
First Month
Ship two major features
Create a framework for measuring web vitals and draft a plan to improve frontend performance.
By 90 Days
Execute plan to improve frontend performance.
Co-own the frontend architecture roadmap alongside the CTO.
Ship product updates daily/weekly with a strong focus on quality.
Ensure dependencies are consistently up to date.
Devise a strategy for automated frontend testing to ensure reliability.
Collaborate closely with the Head of Product, CTO, and AI Engineer to shape the future of the product.
What We’re Looking For
3+ years of experience in full-stack development, ideally with startups or fast-moving teams.
Strong expertise in Next.js, React, and Tailwind for frontend development.
Proficiency in Python for backend/API development.
Familiarity with Terraform, Kubernetes (K8s), and Postgres for infrastructure and data management.
Experience optimizing web performance and improving frontend UX.
A bias for action: You ship fast and iterate based on feedback.
Strong product sense: You think beyond the code and care about delivering an exceptional user experience.
Why Join Us?
Impact: Your work will directly shape the product and the future of the company.
Growth: High ownership, deep collaboration with company and technical leadership.
Speed: We move fast, ship often, and value autonomy.
Culture: Our team is kind, collaborative, inquisitive, and inclusive – and we want to keep it that way. We have high standards for quality and ethics, and help each other learn in order to reach our objectives. We think technology is best built by teams with a diversity of background, thought, and experience.
👒 Every team member is a human first, and we strive to create a culture and environment that supports your career goals and respects all of the hats you wear in life, not just the ones that earn you a paycheck.
Our Team
We were founded in 2023 by SaaS and data experts: Josh (CEO) lead Chartbeat as CTO to $70M+ ARR and exit; David (COO and Head of Product) lead Cortico (MIT spinoff) from 0->1 as COO; Paul (CTO) ran search infrastructure at Reddit and was engineer #7 at Moat (acquired by Oracle for $850M).
Let’s build something great together! 🚀
