Delta6Labs - Senior Software Architect

The role :

We are hiring a Senior Software Architect to own the technical design of the systems Delta6Labs builds across exchanges, wallets and custody, trading infrastructure, and the white-label core that underpins our client deployments. You will report to the CTO / VP Engineering & Product Development and work across every squad without owning any of them.

What you will own :

- System and platform architecture : Design end-to-end architectures for new platforms and major subsystems from context and constraints through service decomposition, data models, integration contracts and deployment topology.

- High-throughput systems : Design high-throughput, low-latency paths order matching, order-book and market-data distribution, risk checks, liquidity routing.

- Wallet and custody architecture : hot, warm and cold segregation, MPC and multi-signature schemes, key lifecycle and rotation, withdrawal approval and limit flows.

- Data architecture : relational modelling, event schemas and their evolution, caching strategy, analytical and time-series stores.

- Non-functional architecture : Define availability and latency targets, failure domains, degradation behaviour, capacity headroom, and disaster-recovery design.

- Reuse and technical strategy : Own the architectural line between the reusable platform core and client-specific extension. Maintain reference architectures for CEX, derivatives, wallet, and launchpad.

- Security and compliance : Threat-model high-value flows, architect integration with compliance vendors (KYC/AML, blockchain analytics), and set standards for smart-contract work.

- Client solutioning : Lead technical discovery, support pre-sales with architecture walkthroughs, and represent Delta6Labs in front of client CTOs and auditors.

- Technical leadership : Write design docs, RFCs and architecture decision records. Run the architecture review practice and mentor senior engineers.

What you must bring :

- 12+ years building production software, including 5+ years as an architect, principal engineer or equivalent senior technical authority.

- Deep distributed-systems expertise : service decomposition, event-driven architecture, streaming and messaging (Kafka, RabbitMQ), consistency and consensus trade-offs.

- Hands-on depth in at least one of C++, Node.js/TypeScript or Python.

- Demonstrated architectural ownership of a high-throughput, low-latency or high-transaction-volume platform in fintech, payments, or trading.

- Strong cloud and infrastructure architecture competence : AWS or GCP, containers and Kubernetes, infrastructure as code, CI/CD, observability.

- Exceptional written communication skills for design documentation.
