Software Engineer (Full Stack)

Nector is a Shopify-native loyalty and rewards platform used by D2C brands to run points, tiers, referrals and rewards programs. Our software sits between live storefronts and real transactions, so correctness, performance and reliability are the product. We're a small team, so you'll own features end to end — schema, API, UI, deploy, and what happens after it ships. If you'd rather be handed a problem than a ticket, you'll do well here.

What you'll work on

Design and build features end to end: data model, REST APIs, background jobs, and the frontend on top of them Merchant-facing dashboards (React SPAs) and storefront widgets that load fast and behave on every theme they land on Our Shopify integration surface — webhooks, extensions, and the platform mechanics the product depends on Your code in production: instrument it, debug it when it misbehaves, fix the root cause Improving system reliability and performance, and refactoring for maintainability as the product grows. This is treated as core work, not something done on the side

What we're looking for

• Depth over familiarity — you should understand how your tools actually work, not just how to use them.
• Java Script & Node.js from first principles. Event loop, promises and microtasks, async behaviour under load, error and memory semantics. You can explain why something is slow or flaky.
• Databases. Schema design, indexing strategy, query plans, transactions, and judgement about which store fits which job.
• System and API design. Rough requirement to clean data model, well-designed REST APIs, and code the next person can extend.
• Frontend fundamentals. Structuring a growing codebase, component and state design, load and render performance, and real CSS fundamentals — box model, layout, specificity. You don't need to be a CSS artist.
