About The Position

We’re looking for a Software Engineer (AI Platform) to design and scale the systems powering Replika’s emotional AI. In this role, you'll work at the intersection of software engineering and AI, collaborating directly with the product team to ship new features to millions of users. We care about your impact, not your title.

Requirements

• Expertise in Python. You can think in terms of syscalls, memory allocation, and network protocols. You can dissect Python's asyncio event loop on a whiteboard, and can engineer around the GIL.
• A strong background in backend development. Experience with microservices and event-driven architectures.
• At ease with containerization technologies (Docker, Kubernetes), CI/CD and cloud platforms.
• Experience with SQL and NoSQL databases.
• Experience building systems that leverage LLMs.
• Mastery of system and software design patterns.
• You are a force multiplier for the team. You identify problems, propose robust solutions, and execute with velocity and a sense of ownership. You are hands-on, curious, and obsessed with building things that work, scale, and last.

Nice To Haves

• Prior experience in B2C organizations.
• Prior exposure to conversational AI, gaming, or social platforms.
• Scala or other JVM languages.

Responsibilities

• Design and build an app that delivers real-time emotional AI experiences at scale (sub-second latency for millions of requests).
• Integrate with LLMs providers, run open-weights models on our GPU clusters, help fine-tune our own LLMs.
• Participate in design reviews, set technical direction, and ensure scalability and reliability of applied AI services.
• Optimize for global growth: high-availability systems, replication, cost-effective API integrations, and scalable embeddings search.

Benefits

• Competitive salary.
• Flexible job schedule and generous vacation policy.
• Unlimited access to the latest AI coding assistants.
• No corporate bs.
• Direct impact: Your work on projects will directly impact millions of worldwide users within months.
