Job summary

Acclaim AI is expanding its Backend Lead role for an AI-powered product built on modern LLM technologies. You will own the platform services domain, partnering closely with product and engineering to turn ambitious ideas into scalable, production-ready systems.

You will lead a small backend team, shaping architecture, driving delivery, and ensuring observability and reliability in a fast-moving environment.

Qualifications

6+ years of experience building and shipping production software.
3+ years hands-on asynchronous Python in production environments.
2+ years of engineering leadership experience, leading teams through execution while remaining deeply technical.
Strong background designing and evolving complex distributed systems, platform-level infrastructure, or other high-scale backend architectures.
Thrive in high-autonomy environments: define technical direction, break down ambiguous problems, prioritize work, and deliver results without detailed specifications or constant guidance.
Product-minded engineering approach: end-to-end ownership of features from shaping solutions to identifying risks and driving delivery.
Strong technical leadership: providing thoughtful feedback, setting a high technical bar, and maximizing team effectiveness.
Practical experience building with LLMs and agentic AI frameworks with up-to-date AI ecosystem awareness.

Responsibilities

Lead a small backend team, owning execution – decomposition, estimation and prioritization.
Continuously assess team performance and growth and adjust team composition when needed – without disrupting delivery.
Build and maintain integrations with third-party services.
Develop our internal LLM agent framework, focusing on scalability, throughput, and parallel processing.
Extend and refine platform architecture to meet evolving needs.
Technically lead the backend/platform track: break down complex work into clear tasks and build processes around product goals.
Adapt quickly as priorities shift, in short feedback loops, keeping the team aligned and driving work to completion.
Work closely with other teams to align on architecture and ownership boundaries.
