Note: The job is a remote job and is open to candidates in USA. Hypersonix Inc. is disrupting the e-commerce space with AI and machine learning capabilities that drive real-time business insights. They are seeking a highly skilled Senior Software Engineer to design, build, and operate scalable backend services that power their AI-driven platform, collaborating with various teams to ensure reliable and secure software delivery.
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
Skills
- 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
- 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
