Job description

About Us

At Félix, we are building the indispensable financial companion for Latinos in the US. We combine an AI-powered, conversational-first interface with real-time financial infrastructure to make cross-border money movement as easy as sending a text. Starting with fast, affordable remittances powered by AI and crypto rails, we are expanding into credit, savings, and wallet services to support the complete immigrant financial journey. Our ambition is to deliver a white-glove financial experience with the simplicity of a conversation to a community the traditional financial system has historically overlooked.

We are a hyper-growth Series C company, backed by over $300 million in funding from top-tier global investors, including Andreessen Horowitz, QED, Castle Island, Switch Ventures, HTwenty, Monashees, General Catalyst Customer Value Fund. This isn't just about the numbers; it's a testament to the trust our investors have in our vision and our team. Additionally, Félix was selected as an “Endeavor Entrepreneur” and was a recipient of the CrossTech Fintech Startups Award.

Joining Félix means you will be part of a team building a legacy, a company that will outlive us all. This is a rare opportunity to apply your skills to a deeply meaningful mission—serving a community that has been underserved for too long because we are obsessed with our customers. We get things done with urgency and focus, driven by extreme ownership over our impact. We collaborate without ego, fostering radical transparency and fierce loyalty so we can grow together. Because we aim for insanely great rather than just good enough, we stay insatiably curious—always experimenting, building the future today, and delivering a product that truly makes our users' lives better.

About the Role

We are looking for a Staff Software Engineer to join our SRE team and lead a group of developers building the product that makes every Félix engineer more productive. This is a hands‑on technical leadership role for a strong software engineer who loves building products and tools, not just operating infrastructure.

You will design and write the software behind our developer platform: integrations between open‑source tools and our Internal Developer Platform (IDP), along with services, internal tools, and automation in Go, running on Kubernetes and GCP. You’ll treat developers as your customers, set the technical direction for your team, raise the engineering bar through code reviews and architectural guidance, and make sure the platform stays reliable, secure, and fast as we scale.

If you’re a strong software engineer with deep cloud‑native experience and want to lead developers building a product that other developers love to use, this is your mission.

Responsibilities

• Product Ownership for Developers: Define and drive the vision, roadmap, and success metrics for an internal developer product that makes engineers measurably more productive. Treat developers as customers: gather feedback, prioritize by impact, and track adoption.
• OSS and IDP Integrations: Design, build, and maintain integrations between open‑source tools and our Internal Developer Platform (IDP), in Go, so that developers get a consistent, self‑service experience instead of stitching tools together themselves.
• Developer Tooling and Automation: Create internal tools, CLIs, services, and automation that remove friction from everyday workflows, such as service scaffolding, environment provisioning, deployments, and day‑2 operations.
• Technical Leadership: Lead and mentor a team of developers within SRE, setting technical direction, standards, and priorities for the developer platform.
• Reliability and Observability: Make the platform and the tools built on it observable and resilient, improving incident response and giving developers clear visibility into their services in production.
• Engineering Excellence: Drive best practices in code quality, testing, documentation, and system design, including clear docs and onboarding for the platform itself.
• Cross‑Functional Collaboration: Partner with product engineering and leadership to align platform work with business priorities, and to make sure what we build solves real developer problems.

Requirements

• Experience: 8+ years of software engineering experience, with time at a Staff level or in a technical leadership role.
• Golang: Strong, hands‑on experience building production systems in Go.
• Kubernetes & Docker: Deep experience designing, deploying, and running containerized applications on Kubernetes.
• GCP: Solid experience with Google Cloud Platform services and cloud‑native architecture.
• Leadership: Proven track record of leading and mentoring developers, through architectural guidance, code reviews, and setting technical direction.
• Systems Thinking: Strong knowledge of distributed systems, system design, and reliability.
• Communication: Ability to explain complex technical decisions clearly and drive alignment across teams.
• Additional Skills: Experience with Python, infrastructure‑as‑code (e.g., Terraform), and fintech or high‑scale, regulated environments is a plus.
• These are the applicable requirements, although equivalent competencies in any of the above will also be considered.

What We Offer

• Competitive salary
• Initial stock options grant
• Annual performance bonus
• Unlimited PTO
• Paid parental leave
• Work model: currently fully remote, with a future transition to a hybrid setup
• Health, dental, and vision plans
• Continuous learning opportunities
• Empowering opportunities for growth in a dynamic entrepreneurial environment
