About Projekt Network
Projekt Network is a professional networking and collaboration platform connecting tradespeople and businesses in the construction and skilled trades industry. It combines a profession social network, a job marketplace, and a project-portfolio showcase in one product, shipped across three coordinated surfaces: a Next.js web app, native iOS/Android apps, and a shared Django cloud API — all hosted cloud-native Google Cloud. We're currently growing quickly and and looking to expand our engineering team The Role
We're seeking a Senior Backend Engineer to join our growing team. You'll work on a sophisticated Django-based platform that handles complex networking features, real-time notifications, job matching, and project collaboration. This is an opportunity to work on a production system serving real users, with modern cloud infrastructure and interesting technical challenges.
Key Responsibilities
Platform Performance & Optimization Profile backend, database, and API performance; find bottlenecks before users feel them. Reduce p95 latency site-wide. Implement caching layers, smarter indexing, async offload, and rate limiting. Build and maintain monitoring dashboards (logs, traces, metrics) and add latency-regression gates to CI.
Scalability Architecture Evaluate and re-architect components to sustain 100× current peak load. Lead decisions on horizontal scaling, autoscaling tuning, and monolith-vs-service boundaries as the system matures. Own infrastructure-as-code and the deployment pipeline.
Reliability & Uptime Own SLAs/SLOs for latency, throughput, and availability, targeting a 99.9% uptime SLA. Design HA database + disaster recovery, set tight alerting thresholds, and keep on-call lightweight and predictable. Keep the platform stable through growth spikes, ad campaigns, and influencer pushes.
Database & Storage Optimization Tune PostgreSQL (Cloud SQL) for high concurrency — query plans, indexing, connection pooling, caching strategies. Future-proof data models for rapid feature expansion.
Security & Infrastructure Hygiene Harden our GCP footprint. Conduct periodic audits of access, IAM permissions, secrets, and backups, and keep secret management and CI security scanning healthy.
