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.
Your Role:
Your job is to build Alpaca's algo trading platform to satisfy our users who expect high quality and performance from their brokerage service. This opportunity is similar to joining AWS or Heroku in their early days, designing and architecting our platform by wearing many different hats in our small team. As an experienced engineer, you will write tons of code and make critical decisions about delivering the best experience to our customers. This certainly requires deep knowledge in both frontend and backend, databases and distributed systems, as well as broad experience from low to high level in CPU-level hardware for high throughput, robust concurrency system design, abstract distributed system architecture for high availability and object-oriented data modeling with long term growth in mind. Joining an early stage startup, the payoff to this highly demanding environment will be worth the effort.
You must have previous software engineering experience with trading or exchange systems (OMS, EMS, exchanges, market making, algorithmic trading, quant trading).
Who You Are (Must-Haves):
- Strong, experienced software engineer with lead experience is preferred
- Coding skills in both low and high level languages around C/C++, Go, Zig, Rust, Java, Scala, Python
- Low latency and high throughput optimization
- Experience with messaging queues and message brokers
- Analytical data-oriented mindset and skills
- Knowledge of algorithms, distributed systems, scalability, high availability, databases, low latency systems and concurrency control
- System design skills with object-oriented data modeling, service-oriented architectures, system abstraction
- Experience with the development and implementation of Order Management systems (OMS) and Risk Management systems (RMS)
Who You Might Be (Nice-to-Haves):
- Algo trading experience (either professional or personal)
- FIX protocol knowledge
- Experience with observability, tracing, continuous profiling and benchmarking
- Financial market (exchange, broker-dealers, clearing, etc.) knowledge
- Experience with financial ledgers
- Statistical and quantitative analysis skills
- Experience with major cloud platforms (we primarily use GCP)
- Experience with Docker and Kubernetes
How We Take Care of You:
- Competitive Salary & Stock Options
- Health Benefits
- New Hire Home-Office Setup: One-time USD $500
- Monthly Stipend: USD $150 per month via a Brex Card
Alpaca is proud to be an equal opportunity workplace dedicated to pursuing and hiring a diverse workforce.

The opportunity.
Join our team as a Senior Software Engineer, building the trading systems at the core of our platform. We have recently been migrating critical trading workflows onto Aeron-based sequenced-log architecture and this role sits at the heart of that platform: you will join one of the teams running services on top of it, matched to the team that best fits your strengths and interests during the interview process.
We are also an AI-native engineering organization: the majority of our pull requests are AI-written and AI-reviewed, supported by in-house agent tooling built directly into our monorepo, so engineers spend their time on design, correctness, and leverage rather than boilerplate.
We are looking for an engineer with a background in capital markets, trading workflows, or electronic trading systems. You have strong skills in system design, you focus on observability and testing, and you leverage AI to move faster without sacrificing quality. Within your first six months, you will tackle key projects such as:
- Feature Expansion: Ship new trading protocol capabilities at high velocity on our Aeron-based platform, supporting a growing client base and increased trading volumes.
- Platform Modernization: Evolve our service architecture — migrating remaining workflows onto the new stack and designing the messaging patterns that connect it to the rest of the platform.
- System Optimization: Improve platform scalability, performance, and test coverage for systems where correctness is the product.
Responsibilities include:
- Design, Develop and Test: Build protocols and features to meet functional and non-functional requirements.
- Support and Maintain: Ensure the reliability and availability of services developed by the team, addressing production issues and continuously improving operational processes.
- Optimize Performance: Improve system performance for low latency and high throughput, crucial in trading systems.
- Collaborate: Work with cross-functional teams to execute projects and contribute to a team-oriented culture.
About You.
We’re seeking an engineer with experience in financial services, trade workflows, or electronic trading systems. Your qualifications include:
- Location: U.S., EST Time Zone
- Industry Experience: 7+ years of experience in software engineering, preferably in capital markets or trading workflows.
- Programming Skills: Proficiency in JVM-based languages (Scala preferred); ability to write clean and maintainable code.
- Distributed Systems: Experience in designing, implementing, and maintaining scalable systems.
- Network Protocols & Messaging: Familiarity with technologies such as TCP/IP, FIX, Kafka, or Aeron.
- Cloud Technologies: Hands-on experience with Kubernetes and Docker.
- AI-Assisted Development: Ability to effectively use AI-assisted development tools (e.g. Claude Code) to accelerate delivery and improve quality while maintaining strong engineering judgment.
- Performance Optimization: Understanding of low latency, high-throughput systems.
- SDLC Practices: Familiarity with Software Development Life Cycle (SDLC) methodologies, including agile practices and CI/CD pipelines.
- Continuous Improvement: Commitment to delivering high-quality solutions.
More About Us and our Tech Stack.
- Languages and Frameworks: We primarily use Scala with ZIO, Pekko and gRPC.
- Messaging Technologies: Our messaging systems include Kafka and Aeron.
- Containerization and Orchestration: We rely on Kubernetes and Docker to build, deliver, and scale containerized services.
- AI-Native Engineering: Agent tooling, automated review, and AI-assisted workflows are built into our development platform.
- Company Culture: We value a collaborative team environment where your technical views and leadership abilities are highly appreciated.
