This role sits at the intersection of product functionality, platform reliability, and enterprise security. Min Qualification: Degree Experience Level: Mid level Experience Length: 5 years Language Requirement: English Working Hours: Full Time - 8 to 5 Applicant Location: Ghana Job descriptions & requirements Job responsibilities: Technical leadership: Define and own the assigned area & platform’s architecture and standards, make trade-offed design decisions, drive high- impact backend improvements across the pipeline, and communicate a clear technical roadmap. Hands-on backend engineering: Build and evolve ingestion, processing, and retrieval services/APIs, strengthen async pipelines (RabbitMQ, retries, backpressure), enhance parsers, and optimize indexing on Qdrant/Elasticsearch for quality and latency. Platform ownership: Run production delivery via Helm/Kubernetes and ArgoCD GitOps, enhance observability with OpenTelemetry/Prometheus/logging/alerts, and enforce multi-tenant data isolation, security, and auditability end to end. A general role is possible, however, depending on specialization other responsibilities may be discussed. These include: RAG and Knowledge Ingestion Experience improving retrieval quality in production using embeddings, vector search, or RAG-style retrieval systems Build and evolve ingestion, processing, and retrieval services/APIs, strengthen async pipelines (RabbitMQ, retries, backpressure), enhance parsers, and optimize indexing on Qdrant/Elasticsearch for quality and latency. Strong experience building ingestion or unstructured data pipelines, ideally involving document parsing across formats such as PDF, Office documents, HTML, or email Retrieval and document intelligence: Partner with AI engineers to advance chunking, embeddings, metadata, and RAG patterns; integrate Python services for agentic workflows; improve retrieval via better indexing/enrichment/evaluation and adopt OCR/layout/table extraction when it moves the needle. Authorization and User Management: Strong domain experience in authorization, identity, or user management systems in production SaaS environments Excellent system design skills: you can model roles, permissions, policy propagation, and service boundaries in a way that stays understandable as the platform grows Experience with enterprise identity concepts such as SSO, RBAC, provisioning, deprovisioning, webhooks, SCIM, or IdP integrations Identity and provisioning integrations: Own external identity integrations (e.g., Zitadel), improve sync for user/role lifecycle and deprovisioning, and implement enterprise features like external groups, SCIM-style provisioning, and metadata sync. Chat and AI Platform AI platform capabilities: Enhance the LLM orchestration layer (streaming, tool calling, multi-model routing), integrate Python/MCP tools, and drive lower latency, higher reliability, and better cost efficiency. Job requirements: 10+ years of backend engineering experience with strong expertise in TypeScript and Node.js and structured backend frameworks like Nest.js Experience as a technical lead for a backend or platform domain, with ownership of architecture, technical direction, and mentoring Hands-on backend engineering: Strong database, indexing, and retrieval experience across PostgreSQL, Elasticsearch, Qdrant, or similar systems System design maturity: you can design for scale, failure handling, service boundaries, and pragmatic trade-offs under real constraints Event-driven backend architecture: Design resilient async workflows (AMQP, background processing) to validate and propagate role/membership updates, with reliable retries and correct behavior under failures and partial reprocessing. Multi-tenant SaaS experience: you understand data isolation, tenant-scoped processing, and enterprise security requirements Platform ownership: Model GraphQL/Prisma/PostgreSQL APIs with strict tenancy, enhance observability (logs/metrics/traces/alerts) for auth/identity flows, and own production delivery via Docker/Kubernetes/Helm and GitOps. Event-driven systems experience: comfortable with asynchronous workflows, retries, idempotency, and eventual consistency in backend services Testing discipline: you write tests for critical business and security logic, not just happy paths Engineering culture: Write robust tests for security-sensitive logic, engage in design/code reviews on auth/identity boundaries, and mentor peers to raise quality, maintainability, and operational discipline.
