Technical Architect (Ruby On Rails, AWS)

Description

Summary: Technical Architect to define architectural direction, establish patterns, and guide engineering teams for Sage HR, focusing on scaling a high-growth platform into an enterprise-grade solution. Highlights: 1. Shape technical direction for Sage HR, a strategic growth product. 2. Act as architectural authority, coach, and consultant to engineering teams. 3. Lead architectural thinking around integrations and platform connectivity. **Nombre de vacante** Technical Architect (Ruby On Rails, AWS) **Descripción** We’re looking for a hands‑on Technical Architect to join our Sage HR organisation in Barcelona and play a key role in shaping the technical direction of one of Sage’s most strategic growth products. Sage HR sits at the centre of our HR and payroll ecosystem, already supporting over 4 million employees globally and continuing to scale rapidly as we invest in its future. This role is deeply embedded with our engineering teams — working alongside product managers, engineers, and technical leaders to define architectural direction, establish patterns, and guide teams. You’ll act as a technical authority, coach, and consultant: setting direction where needed, rolling up your sleeves to solve complex problems, and helping teams navigate scale, technical debt, and an increasingly service‑ and event‑driven architecture. This is a hybrid role requiring 3 days per week in our Barcelona office. **Responsabilidades principales** In this role you’ll: - Act as the architectural authority for Sage HR, defining and evolving the technical architecture as the product continues to scale from a high‑growth platform into an enterprise‑grade solution. - Work closely with engineering teams, product managers, and engineering leaders to translate product strategy and commercial priorities into clear architectural direction, patterns, and technical approaches. - Provide hands‑on architectural leadership, staying close to delivery by guiding teams through complex technical decisions, problem‑solving alongside engineers, and shaping solutions as work progresses. - Establish and embed architectural standards, patterns, and best practices (including service‑based and event‑driven architectures) to address scale, integration, and long‑term maintainability. - Coach and mentor engineers, helping raise technical maturity and architectural capability across teams — particularly in a context with varying seniority and a high proportion of contingent labour. - Lead architectural thinking around integrations and platform connectivity, working across HR and payroll products and supporting an increasingly API‑ and event‑driven ecosystem. - Tackle technical debt and legacy challenges, guiding the evolution of existing systems towards more modern, scalable architectures. - Partner closely with other architects and senior technical leaders across Sage to ensure local decisions align with wider organisational standards while remaining pragmatic and delivery‑focused. - Champion modern engineering practices and AI‑assisted development approaches, helping teams adopt and use tools such as GitHub Copilot and similar technologies where appropriate Skills, Knowledge \& Experience (Requirements) Must Have: - Significant experience working as a Technical Architect or Senior Engineering Leader within product‑led software teams, with a strong focus on architecture that supports real delivery. - Deep hands‑on technical expertise with Ruby on Rails and strong experience designing and operating systems on AWS (experience with Azure transferable). - Proven experience designing and evolving service‑based and/or event‑driven architectures, including APIs and integrations between complex systems. - Strong background in scaling software products, including refactoring existing codebases, evolving monolithic systems, and supporting vertical or horizontal growth. - Excellent problem‑solving skills, with the ability to balance architectural direction and pragmatic delivery. - Experience working closely with engineering teams as a coach and consultant, not just a reviewer — able to guide, challenge, and, when needed, roll up sleeves and contribute directly. - Strong communication skills, with the confidence to defend architectural decisions, influence senior stakeholders, and work collaboratively across disciplines. Nice to Have - Experience working on HR, payroll, or compliance‑sensitive products (not essential). - Exposure to AI‑assisted development tooling (e.g. GitHub Copilot, Claude Code) and interest in applying AI to improve engineering productivity and quality. - Familiarity with multiple database technologies (PostgreSQL, MySQL, SQL Server) and data‑centric architectural challenges. - Experience working in distributed or hybrid teams and navigating complex organisational environments. - Spanish language skills.
