Job description

About Pillexa

Pillexa is a healthcare commerce platform that helps direct-to-consumer brands launch and scale across Canada and the US. We connect brands to a network of board-certified prescribers and licensed pharmacies through a single platform, handling intake, prescription validation, fulfillment, and shipping end-to-end. Our team builds and operates the infrastructure behind a fast-growing category, supporting HIPAA/PIPEDA-compliant systems used by patients and providers every day.

The Role

We are hiring a Senior Software Engineer to take ownership of significant parts of our platform and help shape how we build. You will partner with the leadership team on architecture and technical direction, mentor mid-level engineers through code review and pairing, and set the bar for engineering quality as we scale.

This is a senior role with mentorship responsibilities. It is full-time and on-site in Surrey, BC and we are looking for only local candidates.

Our Technology Stack:

• Frontend:Next.js, TypeScript, Tailwind CSS

• Backend:Node.js (Express), MedusaJS

• Database & Caching:PostgreSQL, Redis

• Payment Processing:Stripe

• Monitoring & Analytics:Datadog, PostHog

Key Responsibilities:

• Lead the design and delivery of major features across the stack

• Drive architectural decisions and document the trade-offs behind them

• Own complex areas of our commerce platform

• Design PostgreSQL schemas and caching strategies for systems that need to scale

• Set up and tune monitoring, alerting, and dashboards in Datadog

• Mentor mid-level/junior engineers through code review, pairing, and technical guidance

• Help define engineering practices, including testing standards, release processes, and on-call

• Partner with leadership on technical roadmap and hiring

Who You Are

• Self-driven. You identify what needs to be done before being asked, scope the work, and drive it to completion. You operate effectively without close oversight.

• A force multiplier. You make the engineers around you better through code review, pairing, and clear technical writing. You see mentorship as part of the job, not an extra.

• Pragmatic. You make sound trade-offs between speed, quality, and complexity, and you can defend the calls you make. You know when to ship and when to invest in foundations.

• Coachable. You hold strong opinions loosely. You take feedback well, change your mind when the evidence warrants it, and admit what you don't know.

• Reliable. You follow through on commitments, communicate early when timelines shift, and own outcomes end-to-end, including what happens after release.

• Quality-minded. You write code that's clear, tested, and maintainable. You raise the bar for the codebase without slowing the team down.

• Collaborative. You communicate clearly in writing and in meetings, partner well with product and operations, and bring people along on technical decisions.

Required Skills:

• 5+ years of professional software engineering experience, with at least 2 in a senior or lead capacity

• Deep proficiency in TypeScript and Next.js

• Strong backend experience with Node.js and Express

• Demonstrated ownership of system design and architecture decisions in production

• Strong PostgreSQL skills, including performance tuning and schema evolution

• Production experience deploying and operating services on AWS

• Experience with Redis or comparable caching in production

• Track record of mentoring other engineers

• Experience working in a startup or as a sole/lead engineer on meaningful systems

Nice to Have

• Experience with MedusaJS, Shopify, or other e-commerce platform experience

• Stripe API integration at scale

• Production experience with Datadog and PostHog

• Healthcare, fintech, or other regulated-industry background (HIPAA, PIPEDA, SOC 2)
