Senior Fullstack Engineer

### Who you are - We're searching for passionate individuals eager to contribute to Alpaca's rapid growth. If you align with our core values—Stay Curious, Have Empathy, and Be Accountable—and are ready to make a significant impact, we encourage you to apply - The ideal candidate is equally comfortable shadowing an operational process and architecting the backend service that replaces it - 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 - Knowledge of service oriented architectures - Experience with major cloud platforms (we primarily use GCP) - Financial market (exchange, broker-dealers, clearing, etc.) 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) - Experience with capacity planning and benchmarking ### What the job involves - We're a dynamic team of 230+ 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! - As an Operations Reliability 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 - 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 ### Benefits - Stock Options - Health benefits from day 1 (internationally, this includes a stipend value to offset medical costs) - New Hire Home-Office Setup: One-time USD $500 - Monthly Stipend: USD $150 per month via a Brex Card - Work with awesome people, clients and partners from around the world - Medical, Dental, Vision - Supplemental health care
