About the Role

As a Senior Software Developer III, you will operate as a technical leader within your team and across the broader engineering organization.

This is an AI-first role: you're expected to lead by example in using agentic-AI tools as the default way of getting work done, not as a bolt-on.

You will shape architecture and design, raise the bar on engineering quality, and partner closely with cross-functional stakeholders to translate technical decisions into business value.

You will primarily work across our cloud platform and architecture, with the versatility to step into a legacy native Windows codebase when refactoring or security work is required. You should be equally comfortable guiding agentic-AI tools to deliver code, reviewing designs, and influencing how the platform evolves.

Location: Fully remote — Colombia

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, prototypes, design discussions, and hands-on delivery across the SDLC.
• Partner with senior developers, architects, and tech leads to define and execute the product and 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.
• Drive automation initiatives at the team level, eliminating manual work in builds, testing, deployment, and operational workflows.
• Champion innovative approaches to platform evolution, tooling, and modernization, including evaluating emerging technologies, build-vs-buy trade-offs, and new capabilities.
• Troubleshoot and eliminate root causes of persistent production issues while driving 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 on skills, prompts, and other agent inputs.
• Define and evolve back-end service architecture and standards for scalability, security, reliability, APIs, and alignment with the product and platform roadmap.
• Design, build, and operate distributed cloud-native services, breaking large initiatives into parallel, incremental deliveries that balance speed, quality, and maintainability.
• Partner with QA, Security, Product, Operations, architects, and technical leads to deliver robust, well-tested services and translate technical decisions into business value.
• Use AI-assisted development tools responsibly, verify generated output, automate suitable workflows, and establish team guardrails and feedback loops.
• Own security posture and CVE-remediation strategy across the cloud platform's dependency graph, with the ability to extend that discipline to a legacy native Windows codebase when required.
• Apply or review applied-cryptography and secure-transport patterns in both cloud services and native components.

AI-Augmented Development Expectations

• Use AI-assisted development tools — including inline completion, conversational assistants, and agentic workflows — as a standard part of your daily workflow.
• Critically evaluate and take ownership of all AI-generated output before it ships, verifying correctness, security, and alignment with architecture and team standards.
• Identify opportunities for agentic automation within your team and lead the rollout of new AI-assisted workflows and tooling.
• Mentor other developers on the effective and responsible use of AI-assisted development tools.
• Help establish team-level practices and guardrails for using AI tools safely and effectively.
• Build and refine feedback loops that improve the team's collective use of AI tooling over time.

Qualifications

• Degree in Computer Science, Software Engineering, or equivalent practical experience.
• 8+ years of professional software development experience with demonstrated impact beyond a single team.
• Proven experience designing and operating distributed, cloud-native, SaaS/multi-tenant platforms at scale, ideally on AWS.
• Strong software engineering fundamentals, including OOP, design patterns, and SOLID principles, with a track record of advocating for code quality.
• Experience with agentic-AI software development practices.
• Experience designing and consuming well-designed HTTP APIs (REST, GraphQL, or similar).
• Experience mentoring developers and influencing architectural decisions across teams.
• Strong written and verbal communication skills, with the ability to operate effectively in fast-moving environments with ambiguity and evolving requirements.
• Strong initiative to improve processes, tools, methodologies, and product quality.
• Deep expertise in cloud-native service architecture, with enough native Windows/C++ background — or willingness to build it — to safely refactor and patch a legacy desktop codebase.
