Join Rockstar, a groundbreaking AI-native fintech startup reshaping the financial landscape. Our client is developing a state-of-the-art banking platform designed to merge human intent with AI execution seamlessly. The team embraces an innovative async-first workflow that combines profound human expertise with advanced AI agents, allowing for the rapid deployment of real banking software.
The Role
As a Technical Product Engineer, you will utilize your background in fintech or banking product development to enhance your product-thinking skills and deliver at the speed of AI. This position transcends traditional product management; it is a Product Builder role where you will define product features, articulate them with exceptional clarity, and collaborate with AI agents to translate specifications into production-ready code. Your primary deliverables will be precise documentation and effective use of cutting-edge AI tools, achieving product development at five times the speed of conventional startups.
What You’ll Do
• Lead the product roadmap for banking and financial integrations.
• Design and prototype banking features such as payments, compliance, and user flows utilizing AI tools.
• Create high-fidelity specifications that can be executed by both humans and AI agents.
• Make real-time architectural decisions and review AI-generated code for accuracy.
• Collaborate with legal, compliance, and operations teams to meet regulatory standards.
• Favor written communication, utilizing memos and documentation over meetings.
Why Writing Is Essential:
In our workflow, language is a powerful tool. Clear specifications and AI prompts drive exponential speed and enhance product quality. Ambiguity can derail progress.

• Excel at refining language to capture every nuance.
• Take pleasure in detailing user experiences, edge cases, and systems meticulously.
• Advocate for documentation as the ultimate source of truth.

• Proficiency in prototyping and evaluating AI-generated code.
Preferred Qualifications:
• Experience as a founder or involvement in side projects.
• Proven track record of delivering developer-facing products or APIs.
• Extensive long-form writing experience (10,000+ words, specifications, essays).
• A passion for precision in language.
• Active experimentation with AI tools to develop software.
• Experience in a fast-growing Fintech or LegalTech startup.
How We Build (AI-Native Workflow):
1. Draft a detailed specification.
2. AI agents generate code, designs, and documentation.
3. Review a short demo video.
4. Approve → Automated pull requests and deployments are created.
You’ll Thrive Here If You:
• Prefer asynchronous communication and value writing over verbal discussions.
• Are a low-ego builder who prioritizes early shipping and rapid iteration.
