You will lead discovery, design architectures, build proof-of-concepts, and clearly explain how LayerZero fits into a customer's existing stack (on-chain, off-chain, and AI/data systems).

This is a hands-on, customer-facing role - not a pure slideware or support function. You'll be expected to whiteboard, write code for demos and POCs, and speak fluently about both Web3 primitives and modern software & architecture.

LayerZero's Solutions Architecture team is the technical front line for our go-to-market motion. We partner closely with Business Development, Forward Deployed Engineering, and core Product/Protocol teams to help customers design and adopt cross-chain architectures built on LayerZero.

We engage with a wide range of organizations - from DeFi protocols and Web3 infrastructure teams, to global banks, asset managers, and enterprises exploring blockchain and AI-driven use cases - and act as trusted advisors on interoperability, security, and system design.

Responsibilities:

Partner with BD and Sales to qualify opportunities, run technical discovery, and map customer requirements to concrete interoperability designs.

Design reference and bespoke architectures that integrate LayerZero with customer systems - including smart contracts, wallets/custody, trading or settlement systems, data platforms, and banking/payments rails.

Lead technical presentations, workshops, and demos, tailoring the depth to audiences ranging from protocol engineers to C-level executives.

Build and validate POCs and pilot integrations, often writing or reviewing code (e.g., smart contracts, backend services, or sample apps) to prove out patterns.

Document architectures, integration plans, and best practices, including sequence diagrams, threat models, and rollout strategies.

Collaborate with Integrations/Forward Deployed Engineering on hand-offs from POC to production, ensuring continuity and a clean path to scale.

Advise on security and reliability for cross-chain flows: failure modes, monitoring, incident response, and operational runbooks.

Stay current on Web3 trends (L1/L2 roadmaps, bridging standards, custody, regulation) and use that knowledge to shape customer strategy.

Gather structured field feedback and feed it back into Product and Protocol teams, influencing our roadmap and SDKs.

Contribute to external-facing content - sample apps, blog posts, talks, and reference architectures that help the ecosystem build better cross-chain systems.

Requirements:

Have 5–10+ years in customer facing technical roles such as Solutions Architect, Sales Engineer, Forward Deployed Engineer, Platform/Infra Engineer, or Protocol Engineer.

Have a strong grasp of blockchain fundamentals and Web3 architecture: consensus basics, L1/L2 and rollups, bridging models, wallets and signing, vaults, custody, and common DeFi patterns.

Are comfortable reading and writing code - ideally in TypeScript, Rust, Go, and/or Solidity - and can quickly understand someone else’s stack.

Have deep experience with integration architecture patterns and APIs (REST/gRPC/WebSockets, webhooks, event streams, OAuth/identity, etc.).

Can explain complex technical concepts simply, adapting your language for engineers, product managers, and business stakeholders.

Enjoy whiteboarding, system design, and storytelling, and can guide a customer from vague ideas to concrete architecture and rollout plans.

Are comfortable in a fast-moving, ambiguous environment, juggling multiple high-stakes accounts at once.

Bonus: have worked with financial services, trading, or other highly regulated industries and understand their risk, compliance, and integration constraints.

You'll work across the stack,from ingesting crypto-asset data from exchanges and block explorers, to building performant APIs, to designing intuitive dashboards that help portfolio managers monitor holdings, vesting schedules, and counterparty risk.

Key Responsibilities

Backend API Development

• Design, implement, and secure REST/GraphQL endpoints for both on-chain and off-chain data.
• Automate data ingestion from exchanges, DeFi protocols, custodians, and OTC counterparties.
• Optimise data pipelines for reliability, low latency, and secure transmission.

Data Normalisation and Storage

• Normalise diverse crypto data types (trades, transfers, vesting events, price feeds).
• Manage both relational and NoSQL databases; fine-tune indexing and partitioning strategies.
• Write performant queries to power real-time dashboards and analytics.

Frontend & UX

• Build and maintain accounting dashboards using React and TypeScript (or similar frameworks).
• Translate complex datasets into intuitive visualisations,tables, charts, KPIs.
• Follow best practices in state management, testing, and accessibility.

Systems Integration

• Integrate internal microservices, third-party APIs, and on-chain data sources.
• Extend or maintain low-code tooling (e.g., Retool) when it accelerates delivery.

Cross-Functional Collaboration

• Work closely with teams across Asset Operations, Finance, and Investments to gather requirements and iterate on solutions.
• Document APIs, data models, and UI components to support easy handoffs and team scaling.

Compliance & Security

• Uphold data privacy principles and enforce crypto-specific security best practices.
• Participate in code reviews and contribute to threat modelling and secure architecture.

Requirements

• Bachelor's or Master's degree in Computer Science, Data Science, or related field.
• 3–5 years of professional full-stack engineering experience.
• Backend proficiency with Go, Node.js, or Python.
• Frontend expertise with React and TypeScript (or equivalent).
• Proven experience designing, building, and consuming APIs at scale, ideally involving crypto or fintech data.
• Advanced SQL skills and comfort working with Postgres, BigQuery, or similar.
• Experience visualising data using tools like D3, Recharts, or Plotly.
• Solid understanding of blockchain fundamentals: on-chain transactions, smart contract events, and DeFi protocols.
• Strong communication skills and ability to collaborate across technical and non-technical teams.
• Comfortable working in ambiguity and iterating quickly in a fast-paced environment.
