51 Rockstar Product Engineer Jobs Hiring Near You

Rockstar is recruiting for a pioneering, AI-native fintech startup. Our client is building a next-generation banking platform from the ground up, designed for a world where human intent and AI execution converge. The team operates with a unique, async-first workflow that blends deep human expertise with AI agents to ship real banking software at extraordinary speed.

The Role

You have built fintech or banking products as an engineer. You have stepped into product thinking. Now you want to do both-at AI speed.

This is not traditional product management; this is a Product Builder role. The candidate will define what to build, describe it with extreme precision, and work alongside AI agents that turn specifications into production code. The primary output is not meetings or Jira tickets; it is clear, rigorous documentation and use of the latest AI tools that becomes the product at 5x the speed of other startups.

What You'll Do

Own product roadmap for banking and financial integrations

Design and prototype banking features (payments, compliance, flows) using AI tools

Write high-fidelity specifications that humans and AI agents execute

Make real-time architectural decisions and validate AI-generated code

Partner with legal, compliance, and operations teams on regulatory requirements

Communicate primarily through memos and documentation, not meetings

Why Writing Is the Core Skill:

In this workflow, language is leverage.

Clear specifications and AI prompts unlock exponential speed and build quality. Ambiguity kills it.

You'll Thrive here If you:

Rewrite sentences until they perfectly capture nuance

Enjoy describing user experience, edge cases, and systems in painful detail

Believe documentation should be the source of truth

What We're Looking For:

Required

5+ years engineering experience in banking or fintech (non-negotiable)

3+ years in product, business, operations, or hybrid roles

Strong understanding of distributed systems and APIs

Ability to prototype and review AI-generated code

Preferred

Founder or side-project experience

Shipped developer-facing products or APIs

Long-form writing experience (10,000+ word documents, specifications, essays)

Obsession with precision in language

Actively experimenting with AI tools to build software

Experience at least one fast-growing Fintech or LegalTech startup

How We Build (AI-Native Workflow)

1. Write a detailed specification

2. AI agents generate code, designs, and documentation

3. Review a short demo video

4. Approve Pull requests and deploys are created automatically

You'll Thrive Here

Async-first thinkers who prefer writing over talking

Low-ego builders who ship early and iterate fast

Self-directed operators who do not need hand-holding

Contrarians who believe meetings are usually a bug

This Role Is NOT for You If You...

Prefer calls over writing

Need heavy external structure or daily check-ins

Want rigid role boundaries ("just PM" or "just engineer")

Are skeptical of AI-driven development

Do your best work only in offices

What We Offer

Competitive salary + meaningful equity

Profit sharing tied to AI workflows that save resources

Fully remote, async-first environment

Time flexibility (including fractional work options)

Culture of low ego, high trust, fast shipping

Interview Process (Async-Friendly)

1. Application + written questions

2. Spec-writing exercise (used to generate real AI output)

3. Technical and product deep dive

4. Language & AI assessment

5. Culture and team conversations

Before You Apply Ask yourself:

Does AI-driven product building excite me?

Do I enjoy writing more than meetings?

Am I comfortable being "ruined for the ordinary"?

If yes, we'd love to meet you.
