ABOUT: CATCHES is a SaaS start-up backed by some of the most influential names in luxury fashion globally. We blend advanced 3D rendering, Artificial Intelligence (AI) and Visual Effects (VFX) techniques to deliver unparalleled shopping experiences for luxury fashion and exclusive events. Robust cloud services and deep Unreal Engine integration power those real-time, immersive experiences.
ROLE: As our Senior Backend Engineer – Unreal Systems & Platform, you’ll split your time between:
- Backend Engineering – building high-throughput, low-latency API services and build pipelines on GCP that drive our real-time 3D platform.
- Unreal Systems Work – authoring plugins, SDKs and C++ modules to extend our rendering & content production features and performance.
You’ll partner with 3D artists, VFX specialists, frontend, backend and data engineers; own technical direction for cloud integration; and coach peers on scalable, secure architecture. If you love solving the full stack of problems—from a cloud API all the way to an Unreal Blueprint node—this is your playground.
RESPONSIBILITIES:
- Design, build and maintain backend APIs, micro-services and data pipelines (C#/.NET) on Google Cloud Platform.
- Develop and maintain Unreal Engine plugins, C++ modules and Blueprint nodes that interface with backend services.
- Implement infrastructure-as-code (Terraform) and fully automated CI/CD with GitHub Actions.
- Drive observability: metrics, tracing, log aggregation and actionable alerts.
- Champion security, performance and cost-efficiency across both cloud and renderer boundaries.
- Collaborate with creative and platform teams to ship end-to-end features, from concept to live operations.
- Mentor engineers, sharing best practices in clean code, SOLID principles and real-time platform patterns.
REQUIREMENTS:
- Extensive experience in backend or real-time 3D platform engineering.
- Production experience with Unreal Engine 4/5 (C++ modules, plugins, networking, RPC, Blueprint exposure).
- Proven track record building cloud-native systems on GCP or Azure (Cloud Run, GKE, Pub/Sub, Postgres).
- Strong C#/.NET and modern C++ skills, some Python experience; comfortable hopping between languages.
- Hands-on ownership of CI/CD pipelines and automated testing for both backend and Unreal client artefacts.
- Deep understanding of relational databases (PostgreSQL or MS SQL) plus caching layers (Redis/Memcached).
- Experience with message queues / event streams (Pub/Sub, RabbitMQ, Kafka).
- Excellent communication skills; thrive in a fully remote, high-autonomy environment.
NICE TO HAVE:
- SRE & Kubernetes expertise (GKE) and Datadog/Prometheus/Grafana observability stacks.
- Experience with large-scale 3D asset pipelines, real-time rendering or streaming media.
- Contributions to open-source Unreal or cloud-native tooling.
- Knowledge of WebGL or other browser-based 3D technologies.
WHAT WORKING WITH CATCHES LOOKS LIKE:
- Fully remote-first, async-friendly, with optional co-working allowances.
- High-trust, low-bureaucracy environment that values experimentation and shipping.
- Early influence on product, architecture and engineering culture.
- A small, experienced team that cares about sustainable pace—minimal meetings, maximal impact.
- Cutting-edge tech, luxury-fashion creativity, and complex real-time challenges combined.
TECH STACK:
- Languages: C#/.NET, C++ (Unreal), Go, Python
- Cloud: GCP (primary), Azure & AWS for specific workloads
- Databases: PostgreSQL, Redis, BigQuery
- Messaging: Pub/Sub, RabbitMQ
- Infra & Ops: Docker, Kubernetes, Terraform, GitHub Actions, Proxmox
- Observability: OpenTelemetry, Grafana, Elastic
