About Faire

Faire is a technology wholesale platform built on the belief that the future is local. Independent retailers around the globe collectively represent a multi-hundred-billion-dollar wholesale market that has historically been fragmented and offline. At Faire, we're using the power of tech, data, and machine learning to connect this thriving community of entrepreneurs across the globe. Picture your favorite boutique in town — we help them discover the best products from around the world to sell in their stores. With the right tools and insights, we believe that we can level the playing field so businesses can grow and local communities can thrive.

We’re looking for smart, resourceful and passionate people to join us as we power the shop local movement. If you believe in community, come join ours.

About this Role:

Independent retailers compete with big-box chains on price every day, and losing on landed cost is how they lose a customer for good. Faire's Insider pod owns the membership program that keeps that from happening — free shipping, exclusive discounts, and benefits that make Faire the obvious place for our best retailers to keep buying.

As a Senior Engineer, you'll own the systems that make that promise real: free-shipping coverage, discount targeting, enrollment and activation, and the lifecycle logic that keeps reminding retailers why they joined. When a retailer sees a discount at checkout or gets nudged to renew, that's your code deciding what they see and when.

You're excited about this role because…

You want to see your code show up directly in what a retailer pays and how they shop, not buried three systems deep
You're energized by experimentation — you'd rather ship a test and read the data than debate in a room
You like owning a domain end to end: backend services, the metrics that measure them, and the roadmap that improves them
You want your work to matter to small business owners, not just to a dashboard

What You'll Do:

Own core services in our Kotlin backend that power free-shipping coverage, discount delivery, and the Insider lifecycle
Partner with Data Science, Product, and Design to prototype and ship improvements to the membership experience
Run experiments that move active Insiders, GMV per Insider, and enrollment rate — and use the results to decide what to build next
Make sure Insider value shows up everywhere it should: cart, checkout, discovery, and after the order ships
Mentor engineers and raise the bar on design reviews, performance, and architecture

We’re Excited About You Because You Have:

Experience: 5+ years in backend systems, with marketplace a nice to have
Technical Depth: Proficiency in Kotlin, Java, or similar object-oriented languages; comfort with distributed systems, service design, and performance optimization.
Data Fluency: Experience integrating with ML-driven decision systems, experimentation frameworks, or real-time data pipelines
Collaboration: Strong communication skills and a track record of partnering with cross-functional stakeholders, from DS to PM, to deliver complex systems.
Mindset: Curiosity and a drive to understand complex market dynamics; passion for applying data and algorithms to real-world business problems.
Education: Bachelor’s degree in Computer Science/Engineering or equivalent industry experience.

Technologies We Use and Teach:

Kotlin, Java, Python
JUnit, Hibernate, Guice, Jersey
HTTP, JSON, Protocol Buffers
MySQL, CockroachDB, Elasticsearch
AWS
