• Be comfortable working with agentic development workflows where appropriate.
• Know how to provide appropriate context and instructions to AI tools to produce reliable results.
• Critically review, test, and validate AI-generated code rather than accepting output without verification.
• Understand the security, privacy, and confidentiality considerations involved when using AI tools with company or client code and data.
• Remain accountable for the quality and correctness of all AI-assisted work.

• Confident communicating directly with international clients.
• Strong presentation and interpersonal skills.
• Comfortable participating in and leading technical interviews.
• Ability to understand business requirements and translate them into technical solutions.
• Ability to ask the right questions during discovery instead of simply following provided requirements.
• Capable of explaining technical decisions, estimates, risks, and trade-offs to non-technical stakeholders.

Ideal Candidate

We are looking for someone who is more than just a strong developer.

The ideal candidate can understand the client's problem, communicate confidently, propose the right technical solution, help us win the opportunity, and then take ownership of delivering it successfully.
