We are hiring for our Treasury team Software Engineers at various levels (II, Senior, and Staff) 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.
• [Staff/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.

[Staff/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.

This is a remote position. However, candidates must be located in the United States, Canada, Netherlands, Poland, or Czech Republic. We do not offer visa sponsorship or assistance.

We are hiring an Engineering Manager for our Processing team to lead Lithic's next phase of growth.

The Processing team builds and maintains the real-time interfaces between Lithic and external payment networks. Every card authorization, clearing message, and settlement file flows through systems this team owns. The team manages both online and batch transaction flows across Mastercard, Visa, and Amex, along with transaction enrichment, disputes processing, and network compliance. The systems we maintain have strict latency and uptime requirements, because they sit on the critical path for every card transaction. The team also manages the physical network peering with card network partners, so infrastructure and networking expertise are important. The team primarily uses Java, Python, and Kotlin on AWS.

What You'll Do:

• Ensure high reliability, low latency, and correctness for Lithic's transaction processing interfaces and related services
• Lead delivery of new capabilities across authorization, clearing/settlement, disputes, and network integration surfaces
• Own and evolve the infrastructure supporting physical network peering with card network partners, ensuring connectivity, failover, and capacity meet reliability requirements
• Raise the bar on operational excellence: observability, incident response, on-call readiness, and pragmatic reliability improvements
• Own initiatives from planning to launch, keeping stakeholders informed and aligned along the way
• Partner closely with Product and cross-functional stakeholders to clarify requirements early and keep engineering time focused on the highest-impact work
• Lead efforts to improve systems, processes, and documentation so new team members can ramp quickly
• Participate in and help evolve the team's on-call rotation

What You Bring

• Experience managing and growing engineers, including coaching, feedback, and hiring
• Strong technical judgment and system design skills, especially for low-latency, high-availability systems, with solid networking and infrastructure knowledge
• Comfort staying close to the work — this is a player-coach role where the manager can unblock, review designs, and occasionally contribute hands-on when needed
• Experience shipping and operating production services with strict uptime and latency requirements
• Experience with or interest in network infrastructure — peering, connectivity, failover, and capacity planning for external partner integrations
• Experience with or interest in learning payment processing — card network protocols, authorization flows, clearing/settlement, or similar domains
• Experience with Java, Python, or Kotlin and AWS (or closely related stacks), and an ability to ramp quickly where the stack is unfamiliar
• Strong cross-functional communication skills and an ability to keep teams aligned under time pressure
• Growth mindset and continuous desire to learn and improve
• An interest in fintech and payments is preferred

The annual US salary range for this role is $169,000 - $265,000 plus equity. This salary range is inclusive of several career levels at Lithic and will be narrowed during the interview process based on the candidate's experience and qualifications.

This is a remote position. However, candidates must be located in the United States, Canada, Netherlands, Poland, or Czech Republic. We do not offer visa sponsorship or assistance.
