Principal Distributed Systems Engineer

Company: Escrow-Tech

Location: Hybrid - minimum 50% on-site in Lagos

Job Type: Independent Retainer - Milestone-Based Deliverable Contract

Duration: July 2026 - December 2026

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 optimisation, Python backend engineering, PostgreSQL security, cryptography, Kubernetes/k3s and edge orchestration.

• Design and implement a multi-threaded Mixed-Integer Linear Programming (MILP) optimisation 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
• Develop the orchestration backend that aggregates distributed edge compute nodes, identifies available capacity and coordinates workload distribution, encryption, execution and result return
• During final execution phase, work with local team in Lagos to deploy production-ready systems, conduct load testing and lead architectural handover sessions

• 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 optimisation
• 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
