Skills
Requirements
What we're looking for
- Strong application-development experience, enough real-world app-dev depth to define how applications should be built well, and to encode that as patterns and quick starts others rely on. This is the core of the role.
- Strong AWS application development and software engineering experience, ideally on developer tooling, delivery platforms, or cloud-native developer workflows.
- You already use AI daily for engineering work. You build with a coding harness/agent as a matter of course, and the more experience you have driving one, the closer to spec-driven development, the better. This is central to how we work, not a bonus.
- Solid knowledge of AWS serverless and event-driven services:
- Lambda
- API Gateway
- Step Functions
- Integration patterns across AWS services
- Experience automating CI/CD, SDLC, and engineering controls:
- GitHub Actions
- Infrastructure as Code
- Automated evidence capture
- Experience building automated governance, compliance, or operational controls into delivery pipelines, turning policy and regulatory requirements into code and evidence.
- Comfortable implementing both:
- Deterministic scripted checks
- Agentic applications that reason over the problem
- Financial services or regulated-industry experience is a plus.
- Good engineering practice as second nature:
- API design
- Automated testing
- Observability
- Documentation
- Secure-by-default delivery
- Comfortable operating independently in a fast-moving programme and contributing from early on.
Nice to have
- Python/FastAPI for building production APIs and services.
- TypeScript/React for web front ends and developer consoles.
- Experience building internal developer platforms or "platform-as-a-product."
- Experience building agentic applications, or designing APIs/CLIs and reusable skills for both human and agent consumers.
- You don't need to have built agentic apps, but experience working through a harness matters.
Pay & benefits
What you'll get
- 23 days of Annual Leave plus the 24th and 31st of December as discretionary days!
- Numerous benefits (Health Care Plan, teleworking compensation, Life and Accident Insurances).
- `Retribución Flexible´ Program: (Meals, Kinder Garden, Transport, online English lessons, Health Care Plan...)
- Free access to several training platforms
- Professional stability and career plans
- UST also, compensates referrals from which you could benefit when you refer professionals.
- The option to pick between 12 or 14 payments along the year.
- Real Work Life Balance measures (flexibility, WFH or remote work policy, compacted hours during summertime...)
- UST Club Platform discounts and gym Access discounts
The role
We are looking for a Senior AWS Application Developer with strong AWS and software engineering expertise, experience building cloud-native solutions, and an AI-first mindset. The ideal candidate enjoys creating scalable platforms, developer tooling, and best-practice frameworks that enable engineering teams to build.
How you'll work
Position 100% remote for candidates based in Spain.
What you'll be like
- A hands-on engineer with a builder's mindset, happy close to the code, shipping practical capability.
- Fluent with AI-assisted engineering. You reach for a harness by default and think in terms of specs and outcomes.
- Opinionated about good application development, and able to turn that judgement into patterns others can follow.
- Pragmatic and self-sufficient, able to make progress where priorities shift as the platform is proven with real users.
- Product-minded and customer-focused, genuinely interested in making the paved road useful.
- Security- and automation-conscious. You build controls and quality in, rather than leaning on manual process.
- Clear and collaborative across platform, application, security, identity, and service-management stakeholders.
