As a Senior Software Developer III, you operate as a technical leader within your team and across the broader engineering organization. You shape architecture and design, raise the bar on engineering quality, mentor other developers, and partner closely with cross-functional stakeholders to translate technical decisions into business value. You are equally comfortable guiding agentic-AI tools to deliver code, reviewing designs, and influencing how the platform evolves. Location: This is a fully remote position located in Colombia.

What You'll Be Doing:
- You build it, you run it. End-to-end accountability for the AI platform in production: architecture, delivery, operations, cost, and quality, with on-call for what you ship. No hand-off to a separate ops or QA function.

- Design, build, and operate agentic AI systems: LLM services, retrieval pipelines, multi-agent orchestration, agent execution runtimes, and human-in-the-loop capabilities.

- Build and operate memory infrastructure for agent systems (storage, retrieval, promotion/demotion mechanics). Applied Science owns promotion criteria and scientific soundness.

- Own LLMOps: the harnesses, pipelines, and infrastructure that keep non-deterministic systems reliable and correct in production, including dynamic model selection by task, cost, and latency.

- Build automated eval infrastructure that continuously compares offline and online metrics and alerts on drift or regression. Applied Science owns the methodology and acceptance thresholds it checks against.

- Evaluate, adopt, and integrate third-party LLMOps and eval platforms where they accelerate delivery over building in-house.

- Build the technical controls, telemetry, and guardrails that enforce compliance frameworks (e.g., ISO 42001, AIUC-1) in the architecture itself.

- Build and maintain the agent definition management APIs and the tool registry definitions reference, keeping definitions stable as tools and models version independently.

- Lead the engineering build of proof-of-concepts. Applied Science defines the architecture bet and validation criteria being tested.

Core Responsibilities
- Create architecture, prototypes, and design proposals that deliver near-term business value while aligning with the future-state product and platform vision.

- Influence technical direction through architecture reviews, RFCs, design discussions, and hands-on collaboration.

- Partner with senior developers, architects, and tech leads to define and execute the product/platform architecture roadmap.

- Balance delivery speed, quality, maintainability, and long-term platform health when making technical decisions.

- Break down large initiatives into parallelizable chunks of work that deliver incremental business value.

- Champion proposals through all phases of the SDLC, from design through production implementation.

- Contribute to improving the core product build, CI/CD pipelines, and overall SDLC.

- Troubleshoot and eliminate root causes of persistent production issues; drive reliability, observability, monitoring, and incident response.

- Keep technical documentation current and create new artifacts as needed.

- Facilitate design discussions within and across teams.

- Represent the team in technical discussions with Tech Leads, Operations, Product/UX, Security, Domain SMEs, and external stakeholders.

- Act as a trusted technical leader, helping teams succeed through collaboration, influence, and shared ownership.

- Mentor other developers through design reviews, joint agentic-AI sessions, and feedback
