Senior Software Engineer (Python) - Operations Automation

About the job

At Allegro, we operate at a massive scale where developer efficiency and seamless internal operations are paramount. Within our multi-product platform team, we design and maintain the critical infrastructure, low-code engines, and intelligent tools that centralize data access and power admin systems company-wide. This high-impact ecosystem ensures that our customer experience teams can work with ultimate efficiency, meaning our platform's stability directly safeguards daily business operations.

The Role

As a Senior Software Engineer, your primary focus will be designing, building, and scaling our next-generation AI solutions. You will play a pivotal role in constructing a smart, autonomous AI agent that serves as an intelligent interface for employees to access distributed data and perform complex tasks seamlessly. This is a highly autonomous role where you will bridge advanced backend engineering with cutting-edge LLM orchestration.

Key Focus Areas

• Building Next-Gen AI Agents: You will architect and develop autonomous AI agents and intelligent assistants using Python, LangGraph, and advanced RAG (Retrieval-Augmented Generation) architectures to automate workflows and optimize information retrieval.

• Modern AI Stack & Observability: Work with a production-ready cloud environment (Azure/GCP) utilizing PostgreSQL and foundational LLM models. You will ensure enterprise-grade reliability and deep tracing of LLM applications by leveraging LangSmith for observability.

• Evolving the Admin Ecosystem: Contribute to the architectural evolution of our internal low-code development platform. You will help eliminate repetitive developer bottlenecks (like security, auditing, and data access) to accelerate tool deployment across the company.

• Versatile Collaboration: Join a mature, cross-functional team of top-class specialists. While your core focus will be Python and AI, you will collaborate within a diverse ecosystem (JVM/Kotlin, React, TypeScript), making an open mindset toward different technologies highly valued.

• True Ownership & Stability: We live by a "you build it, you run it" philosophy. You will actively optimize systems, perform code reviews for other engineering teams, and participate in our casual on-call rotation.

• Have hands-on experience building AI solutions, specifically utilizing LangGraph anf building RAGs

• Want to build solid, clean code, actively participate in code reviews, and enjoy sharing knowledge with the team.

• Have a strong sense of ownership and mission, wanting to directly impact the safety of millions of Allegro users.

• Possess an analytical mindset and a problem-solving attitude.

• Use AI tools to boost daily productivity but maintain critical thinking and never blindly accept code suggestions.

• Are proficient in PostgreSQL and have experience with database migrations and designing integrations via APIs;

• Are excited to join a growing team where they can influence the technical vision and help shape new projects from the ground up within the ecosystem;

What's in it for you:

• Well-located offices (with e.g. fully equipped kitchens, bicycle parking, terraces full of greenery) and excellent work tools (e.g., raised desks, ergonomic chairs, interactive conference rooms).

• A 16" or 14" MacBook Pro or corresponding Dell with Windows (if you don't like Macs) and all the necessary accessories.

• A wide selection of fringe benefits in a cafeteria plan - you choose what you like (e.g., medical, sports or lunch packages, insurance, purchase vouchers).

• English classes that we pay for related to the specific nature of your job.

• A training budget, inter-team tourism (see more here), hackathons, and an internal learning platform where you will find multiple trainings.

• An additional day off for volunteering, which you can use alone, with a team, or with a larger group of people connected by a common goal.

• Social events for Allegro people - Spin Kilometers, Family Day, Fat Thursday, Advent of Code, and many other occasions we enjoy.

And that's just the beginning! You can read more about the benefits here.
