Opportunity

UJET is searching for a Senior Software Engineer (Fullstack) to join our growing team! The ideal candidate is an experienced fullstack engineer who owns epics and features of significant complexity end-to-end across the frontend and backend, and who is meticulous with code style and quality. As a Senior engineer, you will define and execute against timelines, resources, and other constraints, break epics down into tickets, and mentor our L1 and L2 engineers. You are a strong practitioner of AI-driven development — using AI coding tools and agents to accelerate your own delivery while upholding our quality bar.

Responsibilities
  • Own epics and deliver features, services, and refactors of significant complexity across product software engineering — from ticket breakdown through deployment and post-release validation
  • Define and execute against timelines, resources, and other constraints, flagging risks and trade-offs early
  • Break down epics into well-scoped tickets and sequence the work with your team
  • Become the SME for one or more areas of your team's domain and a dependable go-to person within the team
  • Design and build fullstack features and services with high availability, low latency, and auto scalability
  • Author and review technical design documents (TDDs); design service boundaries, data models, and APIs balancing simplicity, performance, and extensibility
  • Partner with PM, Design, QA, PMO, and SRE through the full software development lifecycle, participating in planning, estimation, and prioritization
  • Write idiomatic, well-tested code and provide thoughtful code reviews that uphold engineering standards across the codebase
  • Build and maintain unit, integration, and contract tests; instrument logging, metrics, and tracing so systems are observable in production
  • Participate in the on-call rotation; triage, mitigate, and document production incidents and drive follow-up actions from postmortems
  • Identify and pay down technical debt, modernizing legacy code to protect long-term maintainability
  • Use AI coding assistants and agentic workflows to accelerate delivery, applying our team guardrails and quality standards to anything they produce
  • Mentor L1 and L2 engineers, contribute to onboarding docs, and share knowledge through brown-bags, internal talks, and architecture reviews
  • Communicate openly and transparently, and raise the quality of bug tracking and reporting within your team
Requirements
  • 5+ years' experience in software development, with solid fullstack (frontend and backend) development experience and a track record of owning epics or features of significant complexity
  • You have strong foundational knowledge of modern, distributed computing.
  • You understand the performance characteristics of the services you own and can reason about them quantitatively.
  • Working experience around a breadth of datastores including MySQL, NoSQL, Redis or Elasticsearch
  • Efficiency in software best practice and tools like Git, Docker, CI, 12factor, etc
  • Experience working within a microservice architecture
  • Capable of writing optimal code across the stack, including at least one backend language (Java, Go, Ruby, Python) and a modern frontend framework (e.g., React, Angular)
  • Hands-on proficiency with AI-driven development — AI coding assistants and agentic workflows (e.g., Claude, Copilot, Cursor) — with the judgment to apply them effectively while upholding code quality
  • Experience mentoring less experienced engineers and collaborating cross-functionally in a fast-paced environment
  • Bachelor's Degree in Computer Science or equivalent experience

Please note that this position requires 2 days worked in office in Porto, Portugal weekly. 

Portugal Hiring Range: €60,000 - €70,000 Annually
