About Tesseract Investment

Tesseract is a leading digital asset yield generation platform, trusted by institutional and retail partners worldwide. We help exchanges, custodians, and fintechs offer best-in-class crypto yield products while maintaining the highest standards of security and transparency. Backed by a robust technology team and experienced leadership, Tesseract has scaled rapidly, becoming one of the most credible players in the yield-bearing ecosystem.

We are now entering our next growth phase—expanding our Earn API offering and improving product ownership to deliver a world-class experience to our partners.

The Role

• We are seeking a dynamic and hands-on Product Manager to take full ownership of our Earn API product, the integration that powers partner exchanges and platforms to offer yield products to their end customers.

• This is a critical role for Tesseract, directly impacting revenue growth and client satisfaction. The right candidate will manage the product end-to-end: from defining the roadmap and improving integrations to shaping the client journey and ensuring seamless delivery with engineering.

• For the right person, this role offers a path to Head of Product within 18 months.

What You’ll Do

• Own the Earn API product lifecycle end-to-end – from strategy to execution.

• Drive integrations with partner exchanges & custodians – ensuring frictionless implementation and ongoing performance.

• Work cross-functionally with engineering, commercial, and marketing teams to prioritize features and ship products against tight deadlines.

• Improve documentation, client journeys & onboarding experience for B2B partners.

• Identify and solve critical product challenges – proactively pushing initiatives forward despite resource constraints.

• Roll up your sleeves where needed – whether it’s product marketing, basic UX improvements, or technical documentation.

What Success Looks Like

• Increased API adoption and partner satisfaction.

• Faster, more reliable client integrations.

• Demonstrable improvements in product performance and delivery speed.

• Roadmap clarity and a structured product development process.

What We’re Looking For

• 2- 4 years of product management experience in a crypto native company.

• Proven track record of shipping products in crypto, ideally in yield, staking, custody, or B2B2C API-based products.

• Strong problem-solving track record – e.g., solving major implementation or adoption challenges.

• Comfortable working with engineering teams; understands API-based product design

• Dynamic, outcome-driven personality – someone who gets things done and can influence stakeholders to move fast.

• Hands-on attitude – willing to dive into product marketing, UX basics, and documentation when needed.

• Crypto-native mindset – strong understanding of crypto users, exchanges, and ecosystem players.

Why Join Tesseract?

• Be part of a fast-growing, institutional-grade crypto yield generation platform with global partners.

• Direct impact on business success; this is a critical, high-visibility hire, not a back-office role.

• Mentorship & rapid growth; work directly with the CEO and founder, with a clear path to Head of Product within 18 months.

• Proven resilience & ambition; Tesseract Investment is a profitable, regulated crypto firm (supervised by the Finnish FSA) that has thrived through both bull and bear markets.

• Shape the future of crypto yield products; join the core team driving Tesseract’s next growth phase, expanding its customer base and delivering innovative products to top-tier partners.
