About the role
Performanze
is a digital solution for validating, scaling and optimizing online businesses. We help Companies, Startups and Scaleups increase their performance, boost their profitability and achieve 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 a technical feature will bring 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 meetings with clients to capture requirements, manage expectations on timelines and explain technical solutions in a simple way (without unnecessary jargon).
Product Thinking: You don't just execute a ticket ; you question the "why" and propose improvements in UX or in the 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.
What we're looking for
Experience: 3-5 years working in agile environments.
Frontend: Advanced proficiency in 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).
Nice to have
Translational Communication: Ability to articulate technical concepts to non-technical stakeholders with empathy and clarity.
Proactivity: You don't 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 for the code "working".
What you'll get
Cutting-Edge Environment: Work in the ecosystem of Subdiagonal , with access to disruptive projects and emerging technologies.
Growth: Personalized training plan and mentoring to evolve toward Tech Lead roles.
Performanze Flexibility: Hybrid work, flexible hours (intensive on Fridays) and a culture of impact.
Salary: Commensurate with merit
How you'll work

Hiring process
Assessment: Brief behavioral and logic test (online).
Culture & Client Fit: Interview with People to evaluate your communication and management skills.
Technical & Final Interview: Technical chat with the development team and the CTO to validate your programming "muscle".
