Product Manager — Agentic Payments & Wallets

What we’re building

Nethermind is exploring the next generation of crypto payments and wallet infrastructure — where AI agents, humans, and APIs transact value seamlessly:

• x402 / Agentic Payments: Building “Stripe for x402” — the payments, billing, and analytics infrastructure for machine-to-machine and agent-to-agent commerce. Think: subscriptions, credits, refunds, and developer tooling on top of the x402 protocol.


• Agentic Wallet: A mobile-native, intent-based wallet combining traditional AA (ERC-4337) capabilities with agent-driven automation, adaptive security, and privacy-preserving payments. Users say what they want (“stake $50 in ETH”), and the wallet figures out how.

These are early-stage ventures — some with prototypes, some still in research. The products will evolve based on what we learn from the market.

What we need

A Product Manager who thrives in ambiguity and can take products from 0 → 1. This is not about optimizing existing funnels or shipping incremental features. It’s about:

• Discovering whether a product should exist at all


• Finding the first customers who desperately need it* Shaping the product based on real conversations, not assumptions* Moving fast with small teams to test hypotheses

You’ll work closely with:

• Potential customers: infra providers, agent developers, protocol teams, DeFi power users


• Small, scrappy engineering teams building prototypes


• BD/partnerships to source design partners and early pilots* Leadership to validate venture direction and resource allocation

Role & Responsibilities

1. Customer discovery & market research

• Talk to 50+ potential customers in the first 3 months: compute providers, API sellers, wallet users, agent builders, DeFi protocols


• Identify who has the burning pain: “Who will pay for this today, not in 2 years?”


• Map the competitive landscape and understand why existing solutions fail


• Synthesize insights into clear hypotheses about what to build and for whom

2. Shape the product from zero

• Translate messy customer feedback into a focused product vision


• Define the wedge: the smallest, most compelling version that unlocks the first paying customers


• Write lightweight specs and work directly with engineers to iterate fast


• Kill ideas that don’t validate — pivot without emotional attachment

3. Secure design partners & early pilots

• Source and close 2–5 design partners willing to co-develop and provide real feedback


• Negotiate early pilot terms (paid or strategic value exchange)


• Build relationships that turn into case studies and word-of-mouth

4. Plan go-to-market (GTM)

• Define the initial target segment and positioning (“Who is this for? Why us? Why now?”)


• Create lightweight sales collateral and demo materials


• Work with BD to identify outreach channels and partnership opportunities


• Plan pricing hypotheses and validate willingness to pay

5. Own the narrative & stakeholder alignment

• Communicate progress, learnings, and pivots clearly to leadership


• Build conviction internally for continued investment (or recommend sunsetting)


• Represent the product externally at conferences, calls, and in content

Success looks like (first 6–12 months)

This is not about MRR or DAUs yet. It’s about validation:

• Design partners secured: 2–5 committed partners actively testing with you


• Validated problem-solution fit: Clear evidence that the wedge solves a real pain


• Letters of intent or paid pilots: Early revenue signals, even if small


• Hypothesis log: Documented learnings — what worked, what didn’t, what pivoted


• GTM playbook draft: Initial positioning, ICP, and channel strategy ready to scale


• Team alignment: Engineering, BD, and leadership aligned on next phase

Requirements

• 3+ years in Product Management, with at least 1 year in a 0→1 or early-stage environment (startup, new product line, or venture studio)


• Demonstrated ability to find product-market fit through customer discovery, not just feature shipping


• Strong customer development skills: you’ve done hundreds of customer interviews and can synthesize patterns


• Comfortable with high ambiguity: no roadmap handed to you, limited data, fast pivots


• Excellent written and verbal communication — you can pitch, write specs, and run customer calls


• Familiarity with crypto/Web3: wallets, DeFi basics, on-chain payments, developer tooling


• Bias to action: you ship scrappy MVPs and learn, rather than waiting for perfect specs

Nice to have

• Experience with payments infrastructure (Stripe, payment rails, billing systems)


• Familiarity with AI/agent products and how agents interact with APIs and wallets


• Understanding of account abstraction (ERC-4337), intent-based architectures, or x402 protocol


• Background in B2B developer tools or platform/marketplace products


• Existing network in the crypto/Web3 ecosystem (infra providers, protocols, VCs)

Why this role is different

• You’re not inheriting an established product with existing users — you’re building from scratch


• You’ll have real ownership and influence on product direction


• You’ll work on the frontier of AI + crypto + payments — an emerging category with massive TAM


• Nethermind brings credibility, security expertise, and ecosystem relationships — but you bring the product instincts
