We are seeking a highly skilled Senior Software Engineer to join our foundational engineering team. This is a hands-on individual contributor role where you will work directly with the leadership team to architect, design, and build a next-generation AI-powered enterprise platform from the ground up. This opportunity is ideal for engineers who thrive in zero-to-one environments and enjoy solving complex technical challenges across backend systems, cloud infrastructure, large-scale data processing, and AI-driven applications. You will play a key role in building scalable, secure, and production-grade systems while owning critical architecture and engineering decisions.
Responsibilities:
Architect and build scalable backend systems using Java and Python.
Design and develop high-performance APIs, microservices, and distributed applications.
Build secure and reliable cloud-native infrastructure on AWS.
Design scalable data processing and analytics pipelines.
Develop enterprise-grade applications with a focus on performance, security, and reliability.
Drive system architecture, technical design, and engineering best practices.
Collaborate closely with product and business stakeholders to translate requirements into scalable solutions.
Optimize application performance, availability, and operational efficiency.
Participate in code reviews, design discussions, and technical decision-making.
Infrastructure: Architect and deploy our cloud-native system design entirely on AWS, establishing the core infrastructure for high-scale LLM orchestration and model deployment.
Backend Services: Build high-performance language analytics and RAG (Retrieval-Augmented Generation) pipelines, delivering clean, lightning-fast data APIs to our custom React frontend.
Enterprise SaaS Functionality: Design and implement robust enterprise-grade controls, including Role-Based Access Control (RBAC), advanced data security, real-time collaboration features, and automated subscription billing systems.
Data and Partner Integrations: Build resilient integration layers to ingest and normalize external data feeds from global patent offices, intellectual property registries, research databases, and strategic partners.
Frontend Guidance: Act as the technical anchor for our product ecosystem, guiding front-end development to ensure seamless end-to-end integration and exceptional UI performance.
Growth Optimization: Partner with the business track to design technical instrumentation for product experimentation, user analytics tracking, and conversion marketing funnels.
Requirements:
5+ years of hands-on software engineering experience.
Strong experience in Java for building robust backend services.
Strong experience in Python for API development, automation, and data processing.
Proven expertise in architecting and building applications on AWS (EKS, EC2 RDS, IAM, S3).
Strong understanding of distributed systems, system design, and cloud architecture.
Experience building scalable applications or platforms from scratch (0-to-1 development).
Ability to work independently and take end-to-end ownership of technical initiatives.
Comfortable working in fast-paced startup environments and wearing multiple hats.
