Descrição da oferta de emprego

Senior Full-Stack Engineer (Ruby on Rails + React)

Remote | ⚙️ Full-Time (40+ hrs / week) | Fast-Growth Startup | Contract or Contract-to-Hire

We are a fast-growing, VC-backed retail audit & execution platform that helps brands diagnose planogram compliance and optimize merchandising and category management workflows. Our tools connect real-world retail execution with an intelligent analytics backend powered by data, video workflows, and CVAI.

We’re a small, highly collaborative, and fast-moving team. You’ll work directly with founders, technical leadership, and product teams — influencing architecture decisions, shaping internal tools, and contributing to high-impact product areas.

What You’ll Work On

Key Responsibilities

Core Product Development

Build and maintain data-driven dashboards using Ruby on Rails + React

Develop backend logic, algorithms, and data pipelines in Rails

Improve and expand internal Admin tooling for operations, analytics, and sales

Work on backend components powering the mobile app used by field shoppers; ensure consistency between mobile data flows and dashboard experiences.

Collaboration & Code Quality

Work closely with the CTO to ensure backend data is translated into clean, functional UX

Communicate timelines, tradeoffs, and constraints to non-technical founders

Provide thoughtful code reviews for junior developers; mentor junior developers on architecture and best practices (not people management)

Platform & Infrastructure

Build and integrate APIs between internal systems and external services

Work with third-party tools (marketing automation, payments, workflow systems)

Improve performance, maintainability, and reliability across the codebase

Identify and fix bugs across frontend, backend, web, and mobile

Write unit tests and elevate testing best practices over time

Maintain clean, well-structured, well-documented code

What We’re Looking For

Must Have 5–8+ years of full-stack engineering experience

Strong proficiency with Ruby on Rails (backend, APIs, logic, data flows)

Strong proficiency with React (frontend features, UI state, components)

Experience working across the stack: backend services, APIs, frontend, and internal tools

Ability to work with both new systems and existing / legacy code

Experience with data handling, scaling, and performance optimization

Startup mindset: adaptable, fast, independent, detail-oriented; strong communication skills, especially with non-technical stakeholders

Experience reviewing code and mentoring junior developers

• Bonus Skills: React Native, AWS, Background jobs (Sidekiq, queues, workers), Data modeling or data pipeline experience

Who Thrives Here

You’re a builder at heart.

You enjoy owning full features end-to-end — backend logic, data models, UI, APIs, integrations, dashboards, internal tools.

You like fast-moving environments where engineering decisions directly impact the roadmap. You're comfortable collaborating with both technical and non-technical founders.

If you want the chance to build core product DNA in an early-stage company, this role is for you.

• Opportunities to work on diverse and challenging projects;
• Flexible working conditions;
• 12 vacation days per year;
• 5 sick days per year;
• English classes;
• Access to psychologist support for mental well-being.
