Job Description:

As a Senior Software Engineer in the AI Research & Solutions group, you will be a seasoned contributor building the core systems that power enterprise AI agents. You'll work hands-on developing agentic applications—the software that allows AI to reason, act, and integrate with complex enterprise environments. We're actively exploring Elixir/OTP as a foundation for our agent infrastructure, drawn to its strengths in concurrency, fault-tolerance, and distributed systems. You'll help shape our technical direction and drive key initiatives independently. This role is ideal for engineers who love building systems that think, connect, and abstract complexity—whether your background is in traditional software engineering, academic research, or a quantitative discipline where you learned to express complex ideas in clean code.

Job Responsibility:

Agentic Application Development: Build Agent Components: Design and implement production-grade components for AI agents—tools, orchestration logic, memory systems, and integrations with enterprise data sources
Quality & Reliability: Own the quality of your deliverables, writing robust, well-tested code that operates reliably in production environments
Performance Optimization: Profile and optimize agent behavior, API latencies, and resource consumption to meet enterprise-scale demands
Integration & Systems Thinking: Bridge Systems: Develop connective tissue between AI agent backends and the OutSystems low-code platform, ensuring seamless data flow and secure API contracts
Abstraction Design: Contribute to the design of software abstractions that enable agents to reason about and interact with complex legacy systems and modern architectures alike
Cross-Functional Delivery: Collaborate with researchers, product managers, and platform engineers to translate requirements into working solutions
Mentorship & Technical Growth: Mentor Junior Engineers: Support the growth of engineers through code reviews, pairing sessions, and knowledge sharing
Continuous Learning: Stay current with advances in agentic AI, LLM orchestration frameworks, and systems engineering practices
Documentation: Contribute to internal best practices, architecture decision records, and onboarding materials

Requirements:

Software Engineering Foundation: 5+ years of experience building production software, with demonstrated ability to own and deliver complex features end-to-end
Python Proficiency: Strong hands-on experience with Python
ability to write clean, maintainable, and performant code
AI/ML Systems Exposure: Practical experience working with LLMs, AI agents, or ML systems—whether in industry, research, or open-source projects
API & Integration Skills: Experience designing and consuming REST/gRPC APIs
understanding of distributed systems patterns (queues, event-driven architectures, microservices)
Cloud-Native Familiarity: Working knowledge of containerization (Docker), orchestration (Kubernetes), and cloud platforms (AWS, Azure, or GCP)
Strongly Preferred: Elixir/OTP Experience: Hands-on experience with Elixir and OTP patterns—GenServers, Supervisors, Applications, and Phoenix
Background Flexibility (We Value Diverse Paths): Academic Contributors Welcome: We value candidates from research backgrounds—whether you completed a PhD, contributed to open-source projects during your studies, or built software to support your research in mathematics, physics, philosophy, or computational sciences
Abstraction Thinkers: If you've written code that models complex systems—whether that's physics simulations, formal logic systems, or distributed algorithms—we want to hear from you

Nice to have:

Network Programming: Experience with low-level network code, forwarding plane implementations, packet processing, or socket programming
Functional Programming: Experience with functional languages (Elixir, Erlang, Haskell, OCaml, F#) and their approaches to concurrency and reliability
LLM Orchestration: Hands-on experience with LangChain, Semantic Kernel, or similar agent orchestration frameworks
OutSystems or Low-Code Platforms: Familiarity with OutSystems or similar platforms and their integration patterns

What we offer:

A company that is always growing, changing, and innovating
Real career opportunities
Work colleagues that are as smart, hard-working, and driven as you
Disrupting the status quo is in our DNA
We ask “why” a lot
OutSystems nurtures an inclusive culture of diversity, where everyone feels empowered to be their authentic self and perform at their best
