Ebay Software Engineer Jobs (NOW HIRING)

Opine is a fast-growing AI sales tech startup trusted by leading companies like Docker, Socket Security, BigID, and MaintainX. Opine transforms scattered conversations, notes, and documents into dynamic, living account plans. The platform proactively surfaces risks, aligns every stakeholder, and automates repetitive work from discovery to delivery. The result is faster sales cycles, cleaner handoffs, and consistent execution across sales, presales, and customer success. The founding team were all early employees at cybersecurity unicorn, JupiterOne, and led key engineering and sales teams that led to its rapid growth and 8 figure ARR in 2 years.

As a software engineer at Opine focused on AI agents, you'll help shape how our AI systems think, plan, and take action in the real world. You'll be building the core agent architecture, including multi-step planning, memory, and tool integration, so our agents can reliably handle complex workflows. You'll be working at the cutting edge, building agents that interact with massive volumes of sales data from some of the most forward-thinking companies.

We are looking for someone who is able to navigate across the full cycle of development. From idea/customer conversation, design of the backend system, design of the frontend experience, and management of the infrastructure. You thrive in a bit of chaos and deeply value the ability to own a difficult problem in its entirety.

• Care about speed, want to work with extremely high performers, and are able to navigate across the full cycle of development.
• You have significant experience building and maintaining production AI agents powered by modern language models, handling complex, real-world use cases.
• You've built and shipped evaluation pipelines and datasets to benchmark and improve agent performance in production
• Significant experience working with relational databases like PostgreSQL, and vector databases like pgvector, Pinecone, or Weaviate.
• You've worked with data infrastructure, including technologies like Delta Lake or analytics systems like ClickHouse.
• Strong background building with Node.js or Python
• Bonus: experience managing cloud infrastructure on AWS, Azure, or GCP, and using tools like Terraform
• Bonus: You have an affinity for writing

• Significant equity - Our early team should feel like true owners.
• Competitive base salary - We'll give you a few compensation options that have a salary/equity tradeoff. We care that our employees have the option to optimize for what they care most about.
• Relocating to Raleigh/Durham, NC - We'll pay to relocate you to be with the team.
• Collaborative & high-velocity venture - Be a core part of a collaborative and high-velocity venture with deep entrepreneurial roots where you will be deeply embedded in the early product and business decisions.
• An environment that encourages lightheartedness and humor - We take the business seriously, but that doesn't mean that we need to take ourselves seriously.

We know that joining a startup can be daunting, and getting to know the team is one of the most important aspects of making a decision. Let's get some of that out of the way…
