Are you passionate about building scalable, high-impact applications and solving complex algorithmic challenges? At First Factory, we’re looking for an exceptional Full Stack Engineer to join our team and partner with a premium commercial and luxury real estate client on cutting-edge solutions.

If you thrive in highly technical environments, love deep-dive system design, and pride yourself on writing flawless code under pressure, this is the challenge you’ve been looking for.

We are a software development company with over two decades of experience, boasting a dynamic team of 175+ professionals actively engaged in diverse projects across various industries. We invite you to join us on this journey as we continue to thrive and embrace fresh challenges.

About You

You love algorithmic challenges: You genuinely enjoy solving complex, multi-layered logical puzzles and optimizing code for both time and space complexity.
You are an articulate problem solver: You excel at "thinking out loud," collaborating through complex architecture design under tight timelines, and defending your technical decisions with data.
You thrive under scrutiny: You view rigorous technical evaluations and deep-dive code reviews not as a hurdle, but as an opportunity to showcase your engineering excellence.
You seek deep ownership: You are looking for a singular, high-impact project where you can immerse yourself completely and take full accountability for the end-to-end lifecycle.

Core Requirements

Java Mastery: Strong, production-level experience with Java (8+) and the Spring Framework ecosystem.
Frontend Expertise: Hands-on experience building robust, highly responsive UIs with React and modern JavaScript (ES6+).
Architecture & Microservices: Strong knowledge and practical experience designing and implementing modern Microservices architectures and RESTful APIs.
Advanced Computer Science Fundamentals: Mastery of data structures, algorithmic complexity (Big-O notation), runtime optimization, and high-level system design patterns.
Agile Mindset: Experience collaborating in high-performing, fast-paced Agile teams.
Strong Technical Communication: Advanced English fluency with the ability to articulate complex technical ideas, rationale, and architectural trade-offs clearly to both technical and non-technical stakeholders.

Nice to Have

Experience with CI/CD pipelines and cloud infrastructure (AWS, Azure, or GCP).
A strong portfolio of competitive programming, HackerRank/LeetCode success, or complex open-source contributions.
