Senior Fullstack Engineer

Who We Are: Alpaca is a US-headquartered, global leader in agent-first brokerage infrastructure for stocks, ETFs, options, crypto, fixed income, 24/5 trading, and more. Amongst our subsidiaries, Alpaca is a licensed financial services company, serving hundreds of financial institutions across 40 countries with our institutional-grade APIs. This includes broker-dealers, investment advisors, wealth managers, hedge funds, and crypto exchanges, totalling over 10 million brokerage accounts. Our Team Members: We're a dynamic team of 400+ globally distributed members who thrive working from our favorite places around the world, with teammates spanning the USA, Canada, Japan, Hungary, Nigeria, Brazil, the UK, and beyond! Your Role As an Senior Fullstack Engineer, you will embed directly within brokerage operations functions to systematically eliminate manual work and replace it with durable, auditable software systems. You start by immersing yourself in operational workflows: observing, documenting, and deeply understanding processes end-to-end before designing solutions. Every recurring manual process is treated as a system defect, and every fix you ship is measured by its real-world impact on efficiency and reliability. You will work closely with licensed brokerage staff, domain experts, and platform engineers to build automations and tooling that allow Alpaca's operations to scale globally without scaling headcount linearly. The ideal candidate is equally comfortable shadowing an operational process and architecting the backend service that replaces it. Things You Get To Do Design, build, test, deploy, and monitor production automations and UIs that remove manual steps and reduce operation time. Partner with frontend engineers to productize ops tooling so global teams can run functions with predictable staffing. Execute operational procedures to surface painful manual processes prior to automation. Instrument and report baseline and outcome metrics (MTTC, manual-steps removed, queue sizes, ops satisfaction) and iterate based on measured impact. Produce Platform Opportunity Briefs / RFCs for higher-level platform tooling and automations Collaborate with licensed BD leadership, Compliance, and Security to build auditable, safe automations with role-based access and clear runbooks. Own the full lifecycle of the systems you build, including automated deployment (CI/CD with tools like ArgoCD and Terraform), proactive monitoring, On-call support rotations and incident response, following a "you build it, you run it" philosophy. Build systems with auditability, traceability, and data lineage as a first-class concern to ensure transparency for our auditors and regulators. Who You Are (must-haves) 5+ years of professional software engineering experience, with a proven track record of shipping and operating complex, large-scale systems in production. Strong business sense and understanding of operations Deep, hands-on expertise in Golang, including a strong command of its concurrency models (goroutines, channels), memory management, and standard library. Proven track record of building user-facing features end-to-end with Typescript/React Proficient with SQL and relational databases, preferably PostgreSQL. Demonstrated ability to reason about human workflows as systems, not just software services. Experience with observability, tracing, continuous profiling Exceptional analytical and problem-solving skills, with the ability to deconstruct complex requirements into clear technical components and excellent communication skills for working in a cross-functional environment. High ownership mindset with bias toward durable, structural fixes over tactical patches. Who You Might Be (nice-to-haves) Knowledge of service oriented architectures Experience with major cloud platforms (we primarily use GCP). Financial market knowledge Experience with Docker and Kubernetes. A passion for financial markets or the desire to learn Knowledge of Agile/Scrum methodologies Demonstrable experience in designing, building, and reasoning about distributed systems, including a strong understanding of microservices architecture and API design patterns (e.g., REST, gRPC).
