Solutions Architect

Our company QArea is looking for a Principal Java Solution Architect to take charge of architectural decisions and play an active role in developing complex platform components. This is a hands-on position where you’ll be responsible for designing, implementing, and evolving core parts of the system. You’ll work closely with distributed teams across the US, the EU, and other regions.

Responsibilities:

• design and enhance the architecture for Java-based platform components;
• actively participate in the development of complex features and system-level solutions;
• build and improve integrations with CI/CD systems such as Jenkins, GitLab, and Azure DevOps;
• design and optimize functionality that is data-intensive and database-driven;
• work on secure code execution and protection mechanisms, including anti-tampering and obfuscation concepts;
• ensure the system’s performance, scalability, and reliability;
• collaborate with distributed engineering teams across multiple products;
• review code and provide guidance to engineering teams on architecture and best practices;
• participate in planning and estimating short-term project scopes (2-6 weeks).

What to expect during the project:

• work with a variety of products and technologies;
• engage in short, dynamic projects lasting 2 to 6 weeks, with frequent shifts in context;
• collaborate closely with client-side teams located in the US and EU;
• participate in a mix of architectural planning and hands-on engineering tasks, more like a Principal Engineer | Architect hybrid;
• strong focus on Java + systems + tools + data + security;
• tackle complex technical challenges related to performance, security, and integrations.

Requirements:

must have:

• 15+ years of software engineering experience as Solution Architecture, Principal, or Lead roles;
• strong expertise in Java (core, multithreading, and performance tuning);
• hands-on development experience with complex systems (not solely architecture);
• understanding of code protection, obfuscation, or reverse engineering concepts;
• familiarity with microservices and distributed systems
• strong understanding of:

1. Object-Oriented Programming (OOP) and system design;
2. concurrency and performance optimization;
3. API design and integrations;

• solid experience with SQL and relational databases (MSSQL, PostgreSQL, DB2, or similar);
• experience working with data-intensive applications;
• experience with:

1. CI/CD systems (Jenkins, GitLab CI, Azure DevOps);
2. cross-platform environments (Windows, Linux);

nice to have:

• experience with developer tools, IDE plugins, or testing platforms;
• experience with cloud platforms (AWS, Azure);
• experience with Big Data technologies (e.g., Spark, Hadoop ecosystem);
• background in desktop applications (e.g., Swing or similar) or modern front-end frameworks (e.g., React);

Soft Skills:

• a strong sense of ownership and a problem-solving mindset;
• ability to work in a distributed, multicultural environment;
• comfortable switching between multiple contexts and products;
• strong communication skills with both technical and non-technical stakeholders.
