Software-Engineer, Backend-Engineering, Fintech Jobs

We are hiring for our Treasury team Software Engineers at various levels (II and Senior) who are curious and willing to dive deep and understand our technology and domain in order to solve interesting and hard problems. The Treasury team maintains and builds the backend services that manage the flow of funds between Lithic and third parties. This includes our ledger, ACH and wire infrastructure, and associated reconciliation. The systems we maintain have high standards of reliability and correctness. You will become an expert in the card payments space. The Treasury team primarily uses Python for their tech stack.

The Treasury team builds the mission-critical backend services that orchestrate the flow of funds between Lithic and external financial institutions. This includes engineering our core ledger, ACH and wire infrastructure, and high-precision reconciliation systems. As we handle the movement of money, we build our systems to the highest standards of reliability and correctness.

Our team operates with a high degree of autonomy; we have direct control over what we build and the technical direction we take. Prior fintech experience is not required. You will gain deep expertise in the global payments ecosystem while working with a modern, cloud-native stack primarily utilizing AWS (DynamoDB, Kinesis, Lambda, Step Functions, etc.) and Python.

What You'll Do

• Own initiatives from planning to launch, keeping stakeholders informed and aligned while maintaining a high bar for quality.
• Own your learning of business domains and technical stacks to build a comprehensive mental model of the Treasury ecosystem and how money moves—while the team helps you get there.
• Improve system resilience and ensure high reliability and correctness for Lithic’s ledger and orchestrated funds flows.
• [Senior] Lead the architectural direction and solve our most complex technical challenges, ensuring our systems scale gracefully as we grow.

What You Bring

• Business and technical curiosity: You have a natural drive to peel back layers of a system until you understand the root cause of a problem and how it impacts the broader financial ecosystem.
• A structured approach to learning: You demonstrate a growth mindset centered on building complete mental models of complex systems.
• Autonomy and urgency: You have high agency and thrive in an environment where you are given a problem space rather than a list of tasks, moving with purpose to deliver high-quality solutions.
• [Senior] Experience building distributed systems: You have the technical judgment required to design and scale high-stakes infrastructure where reliability and correctness are foundational.

The annual US salary range for this role is $160,000 - $200,000 plus equity. This salary range may be inclusive of several career levels at Lithic and will be narrowed during the interview process based on the candidate’s experience and qualifications.

Your Role:

As a Senior Engineer, you will be responsible for designing, implementing, and maintaining the systems and services that form the foundation of Alpaca and empower millions of users who are trading billions of dollars worth of assets.

The Ledger Team is responsible for building a modern ledger system, whose purpose is to maintain a complete and correct view of everything that has ever happened in every account. From a business perspective, the ledger provides a structured and organized system for recording and aggregating transactional data. It plays a crucial role in supporting financial reporting, decision-making, and compliance. From an engineering perspective, the ledger serves as the source of truth for many services in the Alpaca ecosystem.

For this role, we are seeking an experienced engineer who is obsessed with delivering defect-free solutions, has proven experience architecting and building at scale, and who is not afraid of challenging conventions or voicing their opinions. In this role, you will have the autonomy to design and implement solutions to achieve defined goals while actively participating in defining those goals in cooperation with a cross-functional team.

Things You Get To Do:

• Collaborate with internal stakeholders–including finance, operations, and product teams–to deliver high-impact features/projects
• Build backend systems/components with integrity, maintainability, scalability, and stability in mind
• Own the delivery of high-visibility features/projects, from design to deployment
• Collaborate with engineering teams to improve the health of Alpaca’s systems

Who You Are (Must-Haves):

• A seasoned engineer with 5+ years of experience working on systems at scale
• Obsessed with performant, defect-free, maintainable code
• A strong problem solver with a proactive mindset
• A collaborator who is capable of creating alignment with technical and non-technical stakeholders alike
• Comfortable working heads-down or tag-teaming problems
• Strong coding skills, preferably in Go
• Ability to debug issues or, better yet, foresee problems and avoid them entirely
• Experience with IDLs (e.g., protobuf), RPC frameworks (e.g., gRPC), cloud platforms (e.g., GCP), and relational databases (e.g., PostgreSQL)

Who You Might Be (Nice-to-Haves):

• Experience in the financial services or accounting industry
• Experience with distributed systems/databases
• Experience with event-driven systems and messaging brokers (e.g., Redpanda)
• Experience working remotely
• Experience working at a startup
