Backend Engineer, Ai (Agent Systems)

There are over 5 billion users using basic applications today such email, notes, tasks, calendar and they’re not AI-native. Our client’s mission is to build proactive applications for anyone in the world, who are not used to complex prompting. They aim to bring intelligence to conversations, errands, organising and workflows, with minimal to no prompting.Their product focuses on achieving high reliability for long-running workflows, persistent context, and real-world task completion. They believe products will greatly reduce hallucinations.Their objective is to organise anyone’s life, allowing us all to spend time on valuable and meaningful things.Role
As a Backend Engineer, AI, you own the inference and orchestration layer that powers every AI interaction in the product. Your work sits between models and users, where latency, correctness, reliability, and cost directly impact real-world experience.You will build and operate production systems that turn model capability into fast, stable, observable APIs used across mobile and desktop clients.Focus
Build and operate backend systems that serve AI-powered features in production.Design inference pipelines, orchestration layers, and service boundaries around models.Own production concerns: monitoring, logging, alerting, and incident response.Optimize latency and throughput across inference, caching, batching, and streaming.Ideal Experiences
Experience running high-throughput, low-latency services.Familiarity with AI inference patterns (LLMs, embeddings, multimodal).Bias toward shipping and learning from production behavior.Outcomes
Backend systems run reliably at scale, handling production AI traffic with low latency and high throughput.APIs are stable, clear, and support seamless integration with frontend and ML systems.Production incidents are quickly detected, diagnosed, and resolved, minimizing user impact.Iterative improvements based on real usage continuously increase system performance and reliability.PythonNodeJsPytorchOpenAI / Anthropic / open-source LLMsSQL & noSQLDockerHow We Work
The best products today in the world were built by small, world class teams. We are a high talent density and hands-on team. We make decisions collectively, move at rapid speed, striking a balance between shipping high quality work and learning. Joining our team requires the ability to bring structure, exercise judgment, and execute independently. Our goal is to put in hands of our users a truly magical productIf there appears to be a fit, we’ll reach to schedule 3, but no more than 4 interviews.Applications are evaluated by our technical team members. Interviews will be conducted via virtual meetings and/or onsite.We value transparency and efficiency, so expect a prompt decision. If you’ve demonstrated the exceptional skills and mindset we’re looking for, we’ll extend an offer to join us. This isn’t just a job offer;
it’s an invitation to be part of a team that’s bringing AI to have practical benefits to billions globally.We appreciate every application we receive. Due to the volume of interest, only candidates selected for an interview will be contacted.
