Software Development Engineer 2

About the RoleLivSYT 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 OwnDesign 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 ForMust have5+ 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 advantageExperience 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 HereYou 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 LivSYTWork 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.

This is a hands-on product engineering role with close collaboration across the CAD, AI, backend, frontend and product teams. About LivSYTLivSYT builds AI-powered software for the engineering and construction ecosystem. Our platform connects engineering design, digital workflows, project controls and automation to help infrastructure and data-center teams move from fragmented, memory-dependent processes toward software-driven engineering and execution. LivSYT is an equal opportunity employer.
