Principal Distributed Systems Engineer

Principal Distributed Systems Engineer

The successful candidate will help architect and own the systems behind a sovereign cloud and distributed edge compute network, including a compute workload exchange designed to manage concurrent resource bids, infrastructure constraints, billing records, and distributed compute capacity. You will work across algorithmic optimization, Python backend engineering, PostgreSQL security, cryptography, Kubernetes/k3s, and edge orchestration.

Responsibilities

• Design and implement a multi-threaded Mixed-Integer Linear Programming (MILP) optimization engine capable of evaluating compute resource bids against constraints such as power, thermal limits, SLA priorities, processor states, and cooling capacity.
• Build an append-only, tamper-evident transaction ledger using SHA-256 hash chaining to track resource allocation, billing events, and energy-curtailment credits, with integrity verification and tamper-detection mechanisms.
• Design and deploy advanced PostgreSQL Row-Level Security (RLS) policies to enforce strict multi-tenant data isolation at the database layer, supported by access-validation middleware and security testing.
• Develop the orchestration backend that aggregates distributed edge compute nodes, identifies available capacity, and coordinates workload distribution, encryption, execution, and result return across the network.
• During the final execution phase, work with the local development team in Lagos to deploy production-ready systems, conduct load testing, and lead structured architectural handover sessions.

Requirements

• Strong experience in distributed systems and high-throughput backend architecture.
• Python backend engineering and performance-critical data pipelines experience.
• Advanced PostgreSQL and multi-tenant database architecture experience.
• Experience with Kubernetes, k3s, Docker, and cloud infrastructure.
• Experience with MILP and mathematical optimization.
• Experience in quantitative engineering, operational research, or resource allocation.
• Experience with cryptographic and tamper-evident data structures.
• Knowledge of SHA-256 and data-integrity verification.
• Experience with distributed edge/IoT orchestration.
• Experience with MQTT and IoT data pipelines.
• Technical documentation and architecture handover experience.
• Experience in quantitative trading infrastructure, operational research platforms, high-throughput fintech systems, or large-scale SaaS multi-tenancy is particularly relevant to the role.
