Role Summary:
Build and integrate the blockchain infrastructure layer that underpins digital asset custody and tokenization platforms. The posting describes this as a hands-on engineering role focused on Layer-1 blockchain integration, core blockchain infrastructure, wallet engineering, and custody-related blockchain workflows.
Key Responsibilities:
- Integrate enterprise systems with existing Layer-1 blockchains and evaluate or extend Layer-1 capabilities to meet custody, scalability, and resiliency needs.
- Engineer for chain-level mechanics such as transaction lifecycle, finality, forks, reorgs, and event propagation, while ensuring blockchain integrations remain reliable under stress conditions and production loads.
- Design and build core blockchain infrastructure services including indexers, event processors, block explorers, observability tooling, chain data services and APIs, and interoperability or cross-chain integration components.
- Build and support wallet architecture, transaction creation and signing workflows, submission pipelines, and integration with custody key management systems such as MPC, HSMs, and signing services.
- Support custody-related blockchain workflows covering on-chain transaction execution, event monitoring and reconciliation, and chain-specific failure handling and recovery patterns.
- Help define safe patterns for interacting with smart contracts and token standards from custody platforms, aligned to custody approvals and risk controls.
- Apply modern engineering practices and AI-augmented development approaches for protocol analysis, code development and testing, documentation, and knowledge sharing. Source-Supported Qualification Themes
- 7+ years of professional software engineering experience.
- Hands-on experience building or integrating blockchain or distributed ledger systems.
- Strong understanding of Layer-1 blockchain protocols and transaction lifecycles.
- Experience building backend services, APIs, and infrastructure components.
- Proficiency in one or more languages such as Go, Java, Rust, Python, or similar.
- Ability to work effectively across custody, security, and platform teams.
- Strongly preferred: experience with blockchain indexers, explorers, or chain analytics systems; familiarity with wallet architecture and blockchain signing workflows; exposure to crypto custody platforms or security-sensitive financial systems; and experience using AI tooling to support complex software development.
Before you apply
Applying takes about a minute. These four things decide how fast it moves after that.
Your profile is current
It's what we read first. Occupations, seniority and locations matter more than a long history.
Two examples you can talk through
Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.
A number in mind
What you're on now and what would make you move. We negotiate better when we know both.
Your notice period
Employers plan around it, and it's the question that stalls offers most often.
Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
