About Aphex

We're the construction planning platform that's replacing outdated spreadsheets with multiplayer tools that delivery teams love. Major contractors like BAM, Balfour Beatty, SKANSKA, Kier, MACE, and Murphy use Aphex to deliver projects ranging from £50 million to multi-billion pound megaprojects.

We're tackling an industry that drives 10% of global GDP yet has seen productivity decline for 20 years. It's time for change.

The role

We're looking for Senior Full Stack Developers based in the Philippines to join our growing team of 20+ developers. You'll bring robust backend skills to help our team, which is mainly working on frontend development. You'll build the systems that help construction teams each day on large projects, such as highways, bridges and hospitals. Your efforts will create infrastructure that millions will rely on in the years to come.

This is a remote-first, hands-on engineering role where you'll tackle complex technical challenges while building products that construction teams genuinely enjoy using. You'll work across our entire stack, from creating delightful user interfaces to architecting robust backend systems that enable real-time collaboration at scale.

Interview Process

Our interview process includes a few stages to ensure a great fit on both sides. This starts with a brief one-way video screening on Willo (only a few minutes), followed by a coding challenge, and then two Google Meet conversations with the team. We value transparency and will guide you through each step.

What you'll do

Build and scale backend services that power real-time collaboration for teams on billion-pound projects
Architect solutions for complex data synchronisation challenges between multiple construction planning systems
Create elegant frontend experiences using React and TypeScript that make complex workflows feel simple
Design and implement WebSocket-based features for live updates across distributed construction teams
Optimise performance for applications handling massive project datasets
Contribute to our serverless infrastructure and event-driven architecture
Participate in code reviews and help elevate engineering standards across the team
Collaborate asynchronously with our global team while predominantly overlapping with PH timezone colleagues
