Product Led Growth Engineer

About Kira

At Kira, we’re on a mission to leverage blockchain to bank the 1 billion underbanked.

We’ve built the first all-in-one infrastructure for launching embedded fintech products — supercharged by vertical AI agents and stablecoins.

We empower neobanks, traditional banks, retailers, and exporters to embed powerful financial tools directly into their apps, helping individuals and businesses move money faster, safer, and cheaper.

The Role

We’re seeking a Product Engineer to collaborate in founder mode; building our embedded Wallet product with the same urgency, ownership, and vision as our team is bringing to other products. You’ll co‑pilot the creation and nurturing of this product, turning it into a foundational fintech primitive driving growth and engagement.

What You’ll Do

You’ll act like a founding engineer, partnership-driven and execution‑obsessed:

• Architect & build the embedded Wallet stack end-to-end, from backend core logic to SDKs that integrate into client apps.

• Design for scalability: ensure the Wallet handles high throughput while maintaining low latency, reliability, and security.

• Collaborate tightly with the Product Designer: bake UX insights directly into the foundation of the product, not just surface UI.

• Iterate quickly: ship early, incorporate feedback, and refine in tight cycles.

• Measure & optimize: track adoption, activation, retention metrics—understand conversion funnels and ship experiments to improve them.

• Ensure reliability: write tests, setup observability, monitor health, and drive testing culture across client integrations.

• Be relentless about performance: profile, optimize, and advocate for better SLAs.

• Engage with customers–build prototypes, demo the Wallet early to clients, gather feedback, and incorporate learnings fast.

• Be paranoid about quality: catch edge cases before they break production; push for robustness and resilience.

What We’re Looking For

• Proven experience building core fintech primitives like wallets, payments, or embeddable components.

• Deep understanding of end-to-end product engineering; backend, SDKs, integrations, performance, testing.

• Strong bias toward founder‑mode ownership; you move fast, own the stack, and deliver outcomes.

• Passion for metrics-driven product velocity; you think in funnels and conversion at every layer.

• Mastery of scalability, reliability, and APIs; you care about what’s beneath the UI.

• Experience launching B2B2C infrastructure, preferably in fintech, payments, or related domains.

• Bonus points if you’ve built SDKs, embeddable APIs, or fintech primitives like wallets, payments, tokens, or agentic onboarding flows.

Why Join Us?

• Massive impact – You’ll shape features that touch thousands of businesses and millions of end-users.

• Cutting-edge tech – AI + blockchain + embedded finance.

• High autonomy – We hire experts and trust them to execute.

• Backed by top fintech founders, ex-YC Partners, and world-class investors.

• Competitive salary + meaningful equity.
