Remote flexibility
Undisclosed
The listing is advertised as remote but does not state which countries or regions candidates may work from.
Why this role is Undisclosed
We only label a role Work from anywhere, Region restricted or Work from home when the employer's own wording says so. We checked this advert under our current rules and found no country or region eligibility requirement in it. We don't guess, so it stays Undisclosed until the employer publishes enough location information. Here is exactly what the advert left out.
- Countries you can work from: Not stated. The advert only gives "Remote", which names no country you must live in.
- Whether the work is remote: Never mentioned. The role reached us through a remote job board, but the advert itself doesn't say the work is remote.
- Working hours: Not stated. No timezone overlap or set hours are mentioned, so assume nothing either way.
Worth a look all the same. Missing wording is usually a rushed job posting rather than a closed door, so ask where you can be based in your first message, before you write a tailored application.
What the employer says
- Source listing states candidate location: "Remote"
What Nomaders makes of it
- No residency or region requirement found in the job description
- Check with the employer before assuming you can work from abroad
The quotes above are the employer's own words; the reading is ours. Always check the original listing and employment terms before working from another country.

Our Ethos
We believe in an open and flat structure. You will be able to grow into the role that most aligns with your goals. Our team members at all levels have the freedom to explore ideas and impact the roadmap and vision of our company.
About the Team
We’re building the next generation of wallet infrastructure at Rain, supporting both custodial and non-custodial architectures. Our team is tackling foundational problems across cryptography, key management, secure computing, and blockchain wallet infrastructure—not simply integrating existing wallet SDKs. We’re looking for exceptional engineering leaders and senior individual contributors who can architect these systems from the ground up, bring deep expertise in one or more areas of wallet security and infrastructure, and have the technical breadth to work across multiple wallet architectures. Most importantly, we want engineers who are excited to push the technical frontier and define what modern wallet infrastructure should look like, rather than reproduce the standard stack that exists today.
What You'll Do
Own the architecture of Rain’s wallet infrastructure, designing secure, scalable systems for custody, key management, transaction signing, authorization, and recovery.
Design flexible signing infrastructure that can support MPC, HSMs, secure enclaves, TEEs, and emerging cryptographic approaches without creating fragmented systems.
Build and evolve wallet systems across multiple account models, including EOAs, smart contract wallets, account abstraction, ERC-4337, embedded wallets, and multichain infrastructure.
Define the boundaries between cryptography and wallet orchestration, including how keys, signing authority, transaction policies, permissions, and authorization interact across the platform.
Architect security-critical key management systems covering key generation, distributed key generation, storage, rotation, backup, recovery, and hardware-backed isolation.
Build highly available signing and transaction infrastructure capable of securely controlling high-value customer assets while maintaining reliable, developer-friendly APIs.
Set the technical direction for wallet security, including threat modeling, policy engines, secrets management, account recovery, authentication, and programmable authorization.
Make foundational build-vs.-buy decisions across cryptography, custody, wallet, and security infrastructure while ensuring the architecture can evolve alongside new blockchain standards and cryptographic techniques.
What We're Looking For
Deep expertise in one or more areas of wallet, custody, cryptography, or security infrastructure, combined with strong distributed systems and architecture fundamentals.
Experience designing or building production wallet, custody, signing, or key management systems, particularly infrastructure responsible for securing high-value assets.
Strong knowledge of applied cryptography, such as MPC, threshold cryptography, threshold signatures, distributed key generation, ECDSA, EdDSA, or secure multiparty computation.
Experience with HSMs, secure enclaves, TEEs, confidential computing, hardware-backed key isolation, or other security-critical infrastructure.
Strong understanding of modern wallet and blockchain account architecture, including EOAs, smart contract wallets, account abstraction, ERC-4337, transaction orchestration, and multichain systems.
Experience designing authentication, authorization, policy, permissions, recovery, or secrets-management systems where security and correctness are critical.
A track record of making high-leverage architectural decisions in complex distributed systems, including evaluating tradeoffs across security, reliability, developer experience, and extensibility.
