Descrizione dell'offerta di lavoro
About Rendi
Rendi is a circular fashion platform for kids.
Families send us their used clothing, we evaluate and refurbish it, and resell it.
B2C sales, a Prime membership, and a B2B2C channel through schools and organizations.
The role
We're hiring a Senior Full?Stack Developer to build alongside our Tech Lead.
The operation runs on a mix of tools, manual processes, and good judgment from the team.
Your job is to build the software that lets it scale.
You work directly with the Tech Lead, starting from scratch.
Most of your time is backend: data model, services, integrations, infrastructure.
But when the fastest way to ship a feature is building the interface yourself, you do that too, especially on the Ops Hub, the internal web tool our operations team uses all day.
What this looks like
A central database as the system of record for inventory, customer profiles, credits, and logistics.
Shopify is the sales channel, not the source of truth.
Backend services with tests, versioning, actual deployment pipelines
Integrations with Shopify, payment providers, logistics carriers, notifications
Automation for cataloging, credits, fulfillment, post?sales support
End?to?end features on the Ops Hub: API, data layer, and the React interface operators work in
Architecture decisions, stack choices, trade?offs: you make them with us, not receive them from above.
Technical direction
Where we're leaning, not a final spec.
Some choices are still open.
Backend: TypeScript, Node.Js, PostgreSQL, AWS (Lambda, RDS, SQS, S3)
Frontend: React, TypeScript, Tailwind CSS
Integrations: Shopify Admin API (GraphQL), webhooks, REST
Tools: Docker, Git, GitHub Actions, Terraform
Likely: Python for AI pipelines
What you'll work on first




Map the current operational processes and turn them into a data model
Define and ship a first version of the core schema
Migrate the core workflows from existing tools to the new system
Build the first Ops Hub screens end?to?end: backend services and the React interface for operations
Backend support for the mobile storefront
Requirements
5+ years building backend systems professionally.
TypeScript and Node.Js as primary stack.
PostgreSQL: schema design, indexing, query optimization.
You've run database migrations in production, shipped schema changes without downtime, handled rollbacks, dealt with data backfills.
AWS in production: Lambda, RDS, S3, SQS or equivalent.
Infrastructure as code (Terraform or equivalent).
You've versioned APIs, managed deprecation cycles, introduced breaking changes without breaking consumers.
React: you can build a working interface, use a design system, close a feature without waiting on a frontend developer.
How you work:
Own problems, not tickets.
You understand the business context and decide accordingly.
Vague requirements don't stop you.
Make a call, write down the assumption, keep moving.
Startup pace is fine by you.
Priorities shift, context is thin, shipping matters more than polish.
Nice to have
Shopify API (metafields, headless commerce)
Logistics or inventory systems
OpenAI API, image pipelines, content generation
Python for data work
Internal tools or operations platforms
Anything public you've built
What we offer
You make the architectural decisions, not inherit them
Day?to?day collaboration with the Tech Lead, not a solo gig
A product that people actually use, not abstract infrastructure
€50,******,000 depending on experience with possibility of stock options
Hybrid in Milan, or fully remote if it works.
We'd want you in Milan 1–2 times a month
