About The Position

Nu is seeking an experienced engineer to address "meta-problems" by improving the tools and processes used by other teams. This role involves designing and implementing high-leverage automation, managing enterprise tool rollouts (like Postman and n8n), and establishing technical governance for next-generation AI workflows. The engineer will be responsible for enterprise automation and platform engineering, including the implementation and maintenance of automation platforms for workflow orchestration and the design/optimization of critical communication infrastructure for internal and transactional messaging. Additionally, the role will drive the technical strategy for AI adoption in engineering workflows, develop governance frameworks for AI coding assistants and agents, and build "Minimum Control Platforms" to balance developer freedom with security and risk requirements. The position also involves defining and enforcing internal tooling standards, conducting "Discovery Design" for new internal products, and acting as a technical reference for the domain, influencing architectural decisions, mentoring senior engineers, and partnering with stakeholders like ITSec and Privacy.

Requirements

Solid Software Engineering Background: Proficiency in modern programming languages (Clojure, Java, or Python preferred) and distributed systems.
Infrastructure & Cloud: Strong hands-on experience with AWS (specifically services like SES, Lambda, IAM) and Infrastructure-as-Code (Terraform/CloudFormation).
Automation Mindset: Experience with workflow automation tools (n8n, Zapier, or custom orchestration engines) and API integration.
AI/LLM Familiarity: Interest or experience in integrating LLMs/AI agents into developer workflows (e.g., Cursor, Copilot, internal AI agents).
Advanced English

Nice To Haves

Governance-Aware: You understand that "efficiency" must be balanced with "security." You can design systems that are safe by default without destroying developer velocity.
Problem Solver: You are comfortable debugging opaque infrastructure issues (like email deliverability drops) one day and writing a strategic policy document the next.
Multiplier: You enjoy documenting your work, creating "Golden Paths" for other engineers, and teaching others how to use the tools you build.

Responsibilities

Lead the implementation and maintenance of automation platforms (e.g., n8n) to orchestrate workflows across business units.
Design and optimize critical communication infrastructure (e.g., AWS SES, email delivery resilience) to ensure high availability for internal and transactional messaging.
Drive the technical strategy for AI adoption within engineering workflows.
Develop governance frameworks to ensure safe, compliant, and effective use of AI coding assistants and agents.
Build "Minimum Control Platforms" that balance developer freedom with security and operational risk requirements.
Define and enforce usage standards for developer tools (e.g., Postman for API lifecycle), ensuring consistency across squads.
Conduct "Discovery Design" for new internal products, ensuring they are inclusive and scalable across different technical frameworks.
Act as a technical reference for the domain, influencing architectural decisions beyond the immediate team.
Mentor senior engineers and partner with stakeholders (ITSec, Privacy) to align technical solutions with company policies.
