About us
We intend to defy the cliches while living them. Change the world working for a scrappy, data-driven, and customer-focused startup that's revolutionizing financial workflows using AI. You will be instrumental in shaping this cutting edge AI product owning features from design to launch.
Change the world working for a scrappy, data-driven, and customer-focused startup that's revolutionizing financial operations with AI-driven workflow automation. We're looking for software engineers with solid foundations in building production systems and a strong applied AI focus. You will be responsible for building functionalities into the product directly and writing production-grade code that brings advanced AI workflows into real-world use.
As an engineer at Genios, you'll focus on making minimum loveable products powered by AI-building scalable, reliable, and user-friendly systems. You'll work across model pipelines, infrastructure, and product layers, but with a clear emphasis on applied AI delivered in production. This role requires ownership, hands-on coding, and the ability to move fast while balancing robustness and innovation.
We have full-time roles available with remote work flexibility, hybrid, or on-site based on your preferences and seniority.
Note: This remote position requires monthly travel to the Bay area or Seattle for in person team meetings.
Key Responsibilities

• Build and scale AI/ML and GenAI pipelines from experimental workflows to production-ready systems.
• Integrate model training, evaluation, deployment, and monitoring into product workflows
• Deploy and manage GenAI solutions such as chatbots, RAG applications, and predictive analytics tools.
• Operationalize LLMs and AI agents, including prompt orchestration, chaining, and fine-tuning.
• Benchmark models, develop evaluation frameworks, and improve reliability and auditability.
• Implement observability, monitoring, and rollback mechanisms to ensure secure, scalable deployments.
• Work across the stack-from backend systems to product SDKs-to deliver AI features directly into user-facing applications.
• Prototype rapidly, gather feedback, and iterate while keeping scale and maintainability in mind.
• Own critical product components and take responsibility for delivering robust, production-grade features.
• Collaborate cross-functionally with data scientists, product managers, and engineers to scope specifications and solve real customer problems.
• Debug complex issues and perform root cause analysis across model pipelines, infrastructure, and product layers to ensure reliability and continuous improvement.

Qualifications

• BS or MS in Computer Science, Statistics, or Mathematics, or equivalent experience.
• Strong software engineering background with proven experience shipping production systems.
• 3+ years of experience in ML/DL pipelines, deployment, and applied AI solutions.
• Proficiency in Python or Go with frameworks like TensorFlow, PyTorch, Scikit-Learn, FastAPI, or gRPC.
• Experience with LLM and AI frameworks such as Langchain, LlamaIndex, Hugging Face Transformers, and OpenAI API.
• Knowledge of RAG architectures, embeddings, reranking models, and LLM-based dialogue systems.
• Experience building and scaling backend platforms, APIs, and microservices.
• Comfortable working full-stack, from model APIs down to user-facing integrations.
• Have shipped AI features that users actually use; production experience over theoretical knowledge.
• Track record of building reliable products with strong attention to detail and usability.
• Autonomous and excited about taking ownership over major initiatives.
• Frequent user of AI products (Cursor, Claude Code, Copilot, etc.) during the development lifecycle.

Bonus Points

• Production experience with LLMs (APIs or custom implementations) at meaningful scale.
• Experience building agentic systems or LLM-enabled products.
• Familiarity with prompt tuning methodologies and frameworks like self-prompting, DSPy, or Banks.
• Experience with performance optimization and high-scale document indexing systems.
• Prior startup experience, grit, and ability to thrive in fast-moving environments.
• Familiarity with databases and comfortable writing SQL queries.
