Backend Engineer (Node.js / Python / Go)

About the Role

Rubiscape’s backend is a distributed microservices mesh that ingests billions of events, orchestrates ML pipelines, and serves real-time analytics to enterprise dashboards — all while guaranteeing the security and compliance posture that regulated Fortune 500 customers demand. As a Backend Engineer, you will design and own services that power one or more of the six studios, working with Kafka, PostgreSQL, Redis, Apache Spark, and Kubernetes as everyday tools — not aspirational technologies. You will apply deep knowledge of distributed systems, API design, and data engineering to achieve platform metrics that matter: 3× faster pipelines, 5× lower TCO, and production deployment in under 90 days.

Key Responsibilities

· Design, build, and own microservices in Node.js (Fastify/NestJS), Python (FastAPI), or Go that serve core platform capabilities — data ingestion, transformation orchestration, model serving, and real-time event processing.

· Architect Kafka-based event streaming solutions for high-throughput data ingestion pipelines (RubiFlow) and real-time alerting (RubiSight), with at-least-once delivery guarantees and consumer group management.

· Design PostgreSQL schemas for multi-tenant SaaS deployments, including row-level security, partitioning strategies, and query plan optimisation for analytical workloads.

· Build and maintain REST and gRPC API contracts used by frontend studios and third-party integrations, with OpenAPI documentation and contract testing (Pact).

· Implement caching strategies with Redis (cache-aside, write-through, pub/sub) to meet sub-100ms response SLOs for interactive platform features.

· Contribute to the platform’s observability stack — defining structured log schemas, custom OpenTelemetry spans, and Grafana dashboard panels for your service area.

· Participate in on-call rotation for backend services, conducting blameless post-mortems and driving reliability improvements to reduce MTTR.

Nice to Have

· Experience with Apache Spark or Flink for large-scale batch and streaming data processing pipelines — directly applicable to RubiFlow’s data foundation studio.

· Prior work integrating LLM APIs (OpenAI, Azure OpenAI, Anthropic) or building retrieval-augmented generation (RAG) pipelines for enterprise AI features (RubiAI).

· Background in IoT protocol handling (MQTT, OPC-UA, CoAP) or time-series databases (TimescaleDB, InfluxDB) relevant to the RubiThings studio.

· Contribution to internal developer platforms, API gateway configuration (Kong, Traefik), or service mesh implementations (Istio).

Requirements

Requirements

· 4+ years of backend engineering experience building distributed, production-grade services in one or more of: Node.js, Python, Go.

· Strong command of relational database internals — query optimisation, index design, transaction isolation levels, and schema migration strategies in PostgreSQL.

· Hands-on experience with Kafka or a comparable message-streaming platform (Pulsar, RabbitMQ) in a high-throughput production environment.

· Solid understanding of microservice design patterns: circuit breaker, saga, CQRS, outbox pattern — and the trade-offs between them in an enterprise context.

· Experience deploying and debugging containerised services on Kubernetes, including resource limits, liveness/readiness probes, and horizontal pod autoscaling.

· Strong security engineering instincts: OAuth 2.0/OIDC flows, secrets management (Vault/Kubernetes secrets), and input validation/sanitisation practices.
