Senior Full Stack Developer

Job Duties

You’ll own the delivery lifecycle end-to-end — from architecture and design to production reliability, technical mentorship, and stakeholder alignment. We’re looking for someone who can turn complex requirements into secure, scalable, high-quality software — and help the team grow in the process.

Key Responsibilities:

• Own architecture and design: create system diagrams, define functional and non-functional requirements (such as scalability, reliability, security and cost), and set integration standards.
• Build and deliver using our technology stack (see below) with focus on quality, performance, and observability.
• Lead initiatives: break down roadmaps, manage small to medium-sized projects, remove blockers, and ensure on-time delivery.
• Plan and prioritize: create execution plans, estimate effort, manage risks, and clearly communicate progress to stakeholders.
• Drive engineering excellence: enforce automated testing (unit, integration, e2e), deep code reviews, branch and release standards, and code quality.
• Document for scale: maintain architecture documents, ADRs, operational guides, and runbooks, ensuring traceability and clarity within agile processes and tools.
• Client interaction: attend remote and in-person meetings, capture requirements, discuss trade-offs, and present solutions clearly.
• Mentor others: guide mid-level and junior developers, share best practices, lead tech talks, and promote a learning culture.
• Partner management: coordinate third parties, validate deliverables, and ensure alignment with project goals.
• Ensure production quality: validate system integrations, instrument logs, metrics, and tracing, define basic SLOs, and participate in post-mortems.
• Continuous learning: explore new technologies, identify process improvements, and propose architectural enhancements.
• Administrative support: handle operational requests and be available for national or international travel when required.

Qualifications

• Education: Bachelor’s degree in Information Technology or related field.
• Experience: 7+ years of professional experience, including technical leadership on complex projects.
• Stack: Backend (Java, Python and .Net Core), Frontend (Angular), Node.js, SQL, strong background in REST API development, microservices and event-driven architectures.
• Cloud: Hands-on experience with AWS or Azure, IAM (Identity and Access Management), storage, managed services and observability.
• Quality & DevOps: Test automation, Git, Gitflow, CI/CD pipelines, Docker, Kubernetes, semantic versioning and promotion across environments.
• Security & Reliability: Familiarity with OWASP Top 10, secret management, least privilege, basic hardening, and observability (logs, metrics, tracing).
• Language: Advanced English (written and spoken, client-facing).
• Profile: Proactive, system thinker, fluent with modern frameworks and best practices in development, testing, and cloud operations.

Nice to have:

• Postgraduate or Master’s degree.
• Spanish proficiency.
• IaC (Terraform) and platform engineering principles.
• Multi-cloud experience (AWS/Azure/GCP) and cost/performance optimization.
• Exposure to performance tuning, caching, messaging/queue systems (e.g., Kafka), and feature flag management.
