Software Development Engineer III - JAVA

Hybrid model - x2 days a week on site

Are you a engineering leader ready to shape the future of software solutions across backend and frontend domains? We're looking for SDE3's with 5+ years of experience in Java, complemented by working knowledge Angular

In this influential role, as an SDE III, you'll bring your engineering depth into a new way of working. You won't just write code — you'll specify, orchestrate, validate, and ship with AI as your primary collaborator. You'll work in a small, mission-driven cross-functional team called a pod. This team consists of three functions: Product, Engineer, and Quality. The team has high agency, shared ownership, and no hand-offs.

Reporting to the Tech Lead, you'll join the Product & Technology Team. Are you ready to be part of a team that's redefining how software gets built in an AI Native setup?

Engineering Mindset — What We Look For

We assess every candidate across six core dimensions:

• AI Fluency — AI is the primary way we engineer. You prompt, evaluate, iterate. Manual coding is a deliberate choice, not the default.
• Cross-Functional Versatility — "That's not my area" doesn't exist. You contribute beyond your discipline, share openly, and communicate clearly across formats.
• Customer and Value Awareness — Ask "why" and "for whom" before "how". Zoom out to see the business, zoom in to trace the bug. Map dependencies before you build.
• Craft — SOLID, DRY, separation of concerns, observability by default. Clean code, right-level testing, CI/CD as hygiene — whether a human or an agent wrote it.
• Technical Curiosity — Build a prototype and break it before reading the docs. Stay curious about how things work.
• Agency & Entrepreneurship — Don't wait for permission. Own outcomes end-to-end, make others successful, challenge the status quo.

If you thrive in technical environments, are passionate about delivering excellence, and want to make a lasting impact, we want to hear from you.

What will you do

• Deliver against the pod's mission — own the full software delivery lifecycle including quality, from design through production and measurement.
• Operate in continuous flow (Kanban) — pull work, respect WIP limits, ship daily.
• Use AI agents as your primary delivery mechanism — code generation, testing, spec writing, deployment.
• Design, build, and debug software across backend and frontend with distributed systems awareness.
• Evaluate and tune agent workflows — steering docs, prompts, rules, skills. You improve the tools you use.
• Write clean, well-tested code and take ownership of quality end-to-end.
• Act as the initial on-call responder, ensuring health and stability of deployed applications.
• Mentor junior developers and contribute to shared tooling, knowledge bases, and the agent foundation kit.

Must Have

• Proficiency in at least one of: Java/Spring Boot, Python, .NET, Go, and Angular and with the use of AI adopt other languages.
• Experience with engineering fundamentals: distributed systems, data structures, API design, database concepts, and cloud computing.
• Experience with clean code practices, TDD, CI/CD, and version control.
• Experience with application monitoring, observability, and production debugging.
• Familiarity with Docker/Kubernetes, microservices, and event-driven architectures.
• Proficiency with AI-assisted development tools (code generation, pair programming, automated testing).
• Experience with agent systems, MCP/tool protocols, or building AI-augmented workflows.
• Experience designing evaluation or observability strategies for AI outputs.

Nice to Have

• Contributions to shared tooling, internal platforms, or open-source projects.
• Background in industries with strict regulatory requirements (gaming, financial services, healthcare).
