Sobre

• About Sierra Studio
• When you apply to Sierra, you join an ecosystem. We connect highly vetted Brazilian talent with growing US companies and work closely with our partners to ensure strong alignment on expectations, culture, and technical bar.
• About our hiring partner
• Our hiring partner started in early 2022 to solve a critical operational problem in the returns processing space.
• While most innovation focused on making returns easier for consumers, this created more returns without fixing the challenges inside warehouses. Operators were relying on pen and paper, whiteboards, and spreadsheets to process returned items — a clear opportunity for a more reliable, scalable system.
• Today, the company supports dozens of logistics providers across multiple facilities, serves hundreds of brands, and has achieved exceptionally low churn and strong user satisfaction. They are preparing for a Series A round later this year.
• The Role
• We are hiring a Senior Backend Engineer to help unblock feature development and scale a production system that already handles real volume.
• This is a hands-on role focused on backend development — not an architect-only position. You’ll work across different backend areas, contributing directly to feature delivery, performance improvements, and integrations.
• Responsibilities
• Develop and maintain backend services primarily written in Go
• Build and evolve REST APIs consumed by web and mobile applications
• Work with Postgres, including query performance and data modeling
• Contribute to feature development across different backend domains (core services and backend-for-frontend)
• Improve system performance and reliability, especially ahead of peak usage periods
• Build and maintain automated tests
• Collaborate closely with product and engineering in a two-week sprint cadence
• Pick up tickets independently and move work forward with minimal oversight
• Requirements
• Senior-level backend experience (typically 5+ years; more is welcome)
• Strong experience with server-side development
• Go experience preferred, but not mandatory for exceptional engineers coming from other backend languages (Java, Python, etc.)
• Solid understanding of REST APIs and relational databases (Postgres)
• Comfortable working in a startup environment with evolving requirements
• Ability to work autonomously, communicate clearly, and ask for help when needed
• Bias toward action and ownership
• Previous experience in startup or fast-paced product teams is highly valued
• Nice to Have (Not Required)
• Prior experience working with Go in production
• Familiarity with cloud environments (GCP or similar)
• Experience improving performance in existing systems
• What We Offer
• Competitive senior-level salary (flexible for exceptional candidates)
• Equity
• Healthcare allowance
• Work-from-home setup stipend
• Unlimited vacation (minimum 2 weeks encouraged)
• Company off-sites twice a year
• 100% remote work environment
• A highly collaborative, low-ego engineering culture
• The opportunity to work on systems that impact real-world operations
• Why Join
• Work on a backend that already matters — not a greenfield experiment
• Join a technically strong, emotionally intelligent team
• Build systems that must perform under real operational constraints
• Be part of a company with strong growth, low churn, and high user trust
• Enjoy a remote culture that values focus, trust, and sustainability
