At Bright Inventions, we value people who take ownership, show initiative, and care about what they build. We work as partners to our clients, so we look for team members who actively suggest improvements, solve problems, and take responsibility for their work and growth.

Being flexible is important to us. We use technology as a tool to bring value, and we appreciate people who are open to learning and using new tools when needed.

We expect effective communication skills, including the ability to both give and receive constructive feedback with empathy. We focus on solutions, not blame. We support each other, share knowledge, and approach challenges with a positive mindset.

About the project

We are working on an innovative Agentic AI platform designed for AppSec teams, effectively integrating with modern software development processes. By using intelligent agents, deep contextual knowledge, and orchestration through MCP, the application transforms security from a blocker into an innovation accelerator.

Requirements include at least 4 years of commercial programming experience as a full-stack developer or similar role, deep working experience with Python, experience with React, AWS, AI tools for coding, testing, and documentation, and solid knowledge of databases (both SQL and NoSQL). Additionally, a strong understanding of HTTP protocol, REST APIs, web communication patterns, proficiency with HTML and CSS, knowledge of testing strategies, and good command of English and Polish are required.
