Requirements

What we're looking for

  • Experience: 3-5 years working in agile environments.

  • Frontend: Advanced mastery of React and TypeScript. Ability to translate Figma designs into pixel-perfect and fluid interfaces.

  • Backend: Solid experience in Node.js (preferred) or Python/PHP, with a focus on security and performance.

  • Databases: Expert management of SQL (PostgreSQL/MySQL) and NoSQL (MongoDB/Redis).

  • Basic DevOps: Knowledge of CI/CD, Docker, and deployment in Cloud environments (AWS, Google Cloud, or Supabase).

  • Translative Communication: Ability to articulate technical concepts to non-technical stakeholders with empathy and clarity.

  • Proactivity: You do not wait for the problem to arrive; you identify bottlenecks and propose the solution before it affects the client.

  • Ownership: You take responsibility for the success of the final product, not just making sure the code "works."

Pay & benefits

What you'll get

  • Cutting-edge Environment: Work in the Subdiagonal ecosystem, with access to disruptive projects and emerging technologies.

  • Growth: Personalized training plan and mentorship to evolve toward Tech Lead roles.

  • Performanze Flexibility: Hybrid work, flexible schedule (intensive on Fridays), and an impact-driven culture.

  • Salary: Commensurate with value

The role

Performanze  is a digital solution to validate, scale, and optimize online businesses. We help Companies, Startups, and Scaleups increase their performance, drive profitability, and achieve their goals. Performanze is part of Subdiagonal, a global group of companies at the forefront of innovation, technology, and entrepreneurship, integrating an ecosystem of companies specialized in transforming complex challenges into disruptive solutions through the use of advanced methodologies, emerging technologies, and scalable business strategies.

We are looking for an engineer who feels comfortable both optimizing a SQL query and explaining to a client why one technical feature will provide more value than another. You will be the bridge between technology and the client's vision.

What you'll do

  • End-to-End Development: Lead the full cycle (architecture, implementation, and deployment) of robust applications in Node.js and React.

  • Client Management & Consulting: Participate in client meetings to capture requirements, manage time expectations, and explain technical solutions in a simple way (without unnecessary technical jargon).

  • Product Thinking: You do not limit yourself to executing a ticket ; you question the "why" and propose improvements in UX or in business logic to maximize the client's ROI.

  • Architecture and APIs: Design scalable APIs (REST/GraphQL) and efficient data models that support business growth.

  • IA-Assisted Ops: Use AI tools (Copilot, code agents) to accelerate development and focus on complex logic and architecture challenges.

Hiring process

  1. Assessment: Brief behavioral and logic test (online).

  2. Culture & Client Fit: Interview with People to evaluate your communication and management skills.

  3. Technical & Final Interview: Technical chat with the development team and the CTO to validate your programming "muscle."
