🏔️ About Sierra Studio

Sierra Studio is an innovative product development firm dedicated to empowering founders and business leaders in their quest to create impactful, meaningful products.

🏢 About The Company

You will be embedded at a growing insurance compliance platform that helps businesses track and manage certificates of insurance — ensuring that vendors, subcontractors, and partners carry the right coverage. Clients span industries like construction, property management, and enterprise services.

The company is undergoing a major transformation: moving from a services-based model to a fully automated software platform, powered by AI and LLMs. This is a pivotal moment to join — the team is rebuilding the product from the ground up with a modern stack, and there is high ownership and real architectural influence available.

The engineering team is cross-functional, collaborative, and predominantly Brazilian. Daily standups happen during Brazilian midday. The culture values autonomy, pair programming, deep work, and strong interpersonal communication.

🖼️ About The Role

As Senior Full Stack Engineer, you will provide strategic technical leadership across a modern TypeScript + React + Python + FastAPI codebase. You will work closely with product managers and engineers to architect, plan, and develop robust full stack solutions.

This is a high-ownership role. You will help define how the product evolves, guide technology decisions, mentor a team, and ensure the team ships with quality and speed. You'll be embedded in the client's cross-functional product team (~10 engineers) while being part of Sierra Studio's talent network.

🔨 What You'll Do

• Lead end-to-end development – Oversee the full product lifecycle from initial idea to launch, ensuring cohesion across backend and frontend.

• Craft high-quality code – Produce clear, efficient code; actively participate in code reviews; champion technical excellence.

• Write tech specs – Translate business needs into technically robust, creative solutions.

• Engage with stakeholders – Collaborate closely with product owners and leadership, turning their vision into technical reality.

• Document thoroughly – Create comprehensive technical documentation to simplify onboarding and maintain institutional knowledge.

• Refine best practices – Proactively identify and implement improvements in engineering workflows and processes.

• Manage and mentor engineers – Provide technical guidance, coaching, and career development. Advocate for your team's needs.

• Drive engineering planning – Lead sprint planning, effort estimation, capacity planning, and release management.

• Architect and evolve the stack – Guide technology decisions and stack improvements; anticipate and address scaling challenges.

🔎 What We're Looking For

• 8+ years of software engineering experience, with at least 3 years in a senior or lead role

• Frontend: TypeScript, React

• Backend: Python, FastAPI, SQLAlchemy

• Cloud: Google Cloud Platform (GCP)

• CI/CD: GitHub Actions or equivalent tooling

• Strong written and verbal communication in English

• Growth mindset — comfortable picking up new frameworks and technologies quickly

Bonus skills:

• Experience with message queue systems (Kafka, Google Pub/Sub)

• Experience with AI-assisted development tools (e.g. Cursor, Claude Code)

• Experience building products using Generative AI / LLMs

🤝 Who We're Looking For

We're looking for a self-motivated engineer with a strong sense of ownership and autonomy. You're proactive, thrive in a high-trust, high-communication environment, and are comfortable leading technical discussions and driving decisions independently when needed.

You work well in pair programming sessions, communicate clearly and early, and bring the team along with you — not just the code.
