Hypersonix.ai is disrupting the e-commerce space with AI, ML, and advanced decision-making capabilities that drive real-time business insights. Built from the ground up with modern technology, our platform simplifies the consumption of data for customers across multiple industry verticals. Job Summary We are looking for a highly skilled Senior Software Engineer with deep expertise in Python backend development to join our engineering team. You will design, build, and operate the scalable, high-performance services that power our AI-driven platform — including the data and inference pipelines behind our real-time insights. You’ll partner closely with Product, Data Science / ML, and Frontend Engineering to ship reliable, secure, and observable software. This role suits someone who enjoys solving complex distributed-systems problems, writes clean and well-tested code, and wants to shape the architecture of a data- and AI-intensive platform. Roles & Responsibilities • Design, develop, and operate scalable backend services and microservices using modern Python (3.11+). • Build high-performance, well-documented RESTful and/or async APIs (FastAPI / Flask), with attention to latency, throughput, and reliability. • Write clean, typed, reusable, and testable code, backed by automated tests (pytest) and meaningful coverage. • Design systems for high availability, horizontal scalability, and low latency; reason about failure modes, backpressure, and graceful degradation. • Integrate and serve AI/ML capabilities — model/LLM API integration, retrieval pipelines (RAG), vector search, and inference endpoints — in collaboration with Data Science. • Integrate relational, NoSQL, caching, and vector databases, plus cloud data warehouses (Snowflake) and cloud-based storage. • Instrument services for observability (structured logging, metrics, tracing) and own production troubleshooting and performance optimization. • Implement security best practices: authentication, authorization, secrets management, and data protection. • Participate in architecture discussions, design reviews, and code reviews; help define and uphold engineering standards. • Mentor junior engineers and contribute to a strong engineering culture. • Work with DevOps / Platform teams on CI/CD pipelines, infrastructure-as-code, and deployment automation. Required Qualifications • Bachelor’s or Master’s degree in Computer Science, Engineering, or a related technical field (or equivalent practical experience). • 5–7 years of professional software development experience. • Strong proficiency in Python, including type hints and at least one modern web/API framework (FastAPI and/or Flask). • Solid experience designing and building RESTful APIs, web services, and microservices. • Strong grasp of object-oriented and/or functional design, data structures, and software design principles. • Hands-on experience with version control (Git) and CI/CD pipelines (e.g., GitHub Actions, GitLab CI, or similar). • Experience with both relational (e.g., PostgreSQL/MySQL) and NoSQL databases, plus caching (e.g., Redis). • Good understanding of distributed systems, concurrency, and scalable application architecture. • Strong debugging, problem-solving, and analytical skills. • Excellent communication and collaboration abilities; comfortable working in a remote, distributed team. Desired Qualifications • Experience with cloud platforms, ideally AWS (e.g., ECS/EKS, Lambda, S3, RDS). • Familiarity with containerization and orchestration (Docker, Kubernetes). • Experience with asynchronous programming in Python (asyncio) and event-driven architectures. • Experience integrating LLMs or ML models into production (e.g., model/inference APIs, RAG, vector databases such as pgvector, Pinecone, or Weaviate). • Experience with cloud data warehouses such as Snowflake (e.g., data modeling, performance tuning, and building data pipelines or analytics workloads). • Familiarity with infrastructure-as-code (Terraform, AWS CDK) and observability tooling (OpenTelemetry, Datadog, Prometheus/Grafana). • Understanding of authentication and authorization protocols (OAuth 2.0, JWT, SSO) and security best practices. • Basic knowledge of JavaScript, HTML5, and CSS3. • Experience in Agile/Scrum environments. • Exposure to data-intensive or AI/ML platforms.
