Software Development Engineer 2

About the Role

LivSYT is building an AI-native engineering platform that automates complex infrastructure design - from engineering calculations and 3D/CAD models to drawings and downstream project workflows.

We are looking for a Senior Backend Engineer to build the platform layer connecting our CAD/geometry engine, AI systems and cloud infrastructure. This is not a conventional CRUD/API development role. You will work on large engineering models, distributed computation, real-time collaboration, versioning, multi-user concurrency and secure enterprise deployments. You will have significant ownership over architecture and technical decisions as the platform scales globally.

What You Will Own

• Design and build high-performance backend services using Python, FastAPI and asynchronous programming.
• Architect APIs and distributed services connecting CAD/geometry engines, AI agents and cloud services.
• Build systems for processing and managing large engineering/CAD models and binary files, including DWG, IFC and BREP workflows.
• Design real-time multi-user collaboration: concurrency, versioning, locking, conflict resolution and recovery.
• Build event-driven and asynchronous workflows using Kafka, RabbitMQ, SQS or equivalent systems.
• Design scalable data architectures using PostgreSQL, Redis and object storage such as S3.
• Own performance, observability, reliability and production troubleshooting for cloud-native services on AWS.
• Design secure multi-tenant architecture including RBAC/ABAC, auditability, encryption and enterprise data isolation.
• Build and improve CI/CD for backend services using Git, Docker and modern deployment pipelines.
• Work directly with CAD, AI, frontend and product engineers to take systems from architecture through production.

What We Are Looking For

Must have

• 5+ years building production backend or platform systems.
• Excellent Python fundamentals and production experience with FastAPI, Django, Flask or another modern Python backend framework.
• Strong understanding of asynchronous programming, concurrency, distributed systems and service-oriented architecture.
• Strong PostgreSQL fundamentals: schema design, transactions, indexing and query optimization.
• Experience with event/message systems such as Kafka, RabbitMQ or SQS.
• Production experience with AWS/GCP/Azure, Docker and CI/CD.
• Strong system-design ability and experience diagnosing performance, scalability and reliability problems in production.
• Evidence of owning systems end-to-end - not only implementing tickets.

Strong advantage

• Experience with large-file or binary-data processing.
• WebSockets, collaborative editing, distributed locking, version-control or other real-time systems.
• Kubernetes, ECS or EKS and production observability tooling.
• CAD, GIS, gaming engines, simulation, geometry or 3D systems.
• AI/LLM infrastructure, agent integration or model-serving workflows.
• Enterprise multi-tenant SaaS, permissions, security and audit systems.

The Kind of Engineer Who Will Thrive Here

• You enjoy hard systems problems and can move between architecture, code, debugging and production.
• You make pragmatic trade-offs between speed, scalability and engineering quality.
• You can challenge an architecture constructively and then take ownership of the solution.
• You are comfortable working closely with domain engineers, product leaders and other senior engineers.
• You want to build core technology rather than maintain a mature legacy platform.

Why LivSYT

• Work at the intersection of CAD, AI and distributed cloud systems.
• Build software that helps automate how major physical infrastructure is designed and delivered.
• Own meaningful parts of the core platform while the architecture is still being built.
• Work directly with senior engineering and product leadership with substantial technical autonomy.
• See your systems used on real-world transportation and data-center engineering workflows.
