The Intelligence Layer for Post-Transaction Risk

Casap is fundamentally transforming how financial institutions handle post-transaction risk, starting with a mission to eliminate first-party fraud. First-party fraud—where users dispute legitimate transactions they actually made, often referred to as "friendly fraud"—is a staggering $100 billion problem that is growing rapidly and now accounts for thirty to fifty percent of all fraud losses globally. Traditionally, financial institutions have been trapped in manual, slow workflows with impossible compliance deadlines dictated by strict regulatory frameworks. Investigators are frequently forced to manually review PDFs, cross-reference merchant data, check IP addresses, and parse through customer communication logs just to resolve a single dispute. Because of the sheer volume of claims and the stringent regulatory requirements to resolve them within a specific timeframe, banks often auto-approve claims below certain monetary thresholds simply to avoid regulatory penalties. Alternatively, they hire massive back-office operations teams to manually process each dispute, which severely impacts their bottom line and operational efficiency.

Casap provides the first true intelligence layer for post-transaction risk, using sophisticated agentic AI to replace these legacy manual workflows with AI-native infrastructure built explicitly for scale, speed, and precision. By automating the ingestion of dispute evidence, analyzing the likelihood of fraud, and interfacing directly with core banking systems, Casap fundamentally changes the unit economics of dispute resolution. Their platform gives consumers much-needed transparency regarding the status of their claims while providing financial institutions a faster, smarter way to manage risk. The results are transformative: institutions utilizing Casap can cut first-party fraud losses by up to fifty-one percent and handle four to five times more fraud volume without adding a single headcount to their operations teams. This allows banks to redirect their resources toward complex, high-value investigations rather than drowning in low-value, repetitive dispute processing.

A Culture of Intentional Velocity

Founded by product leaders who previously scaled risk and product infrastructure at Robinhood and Chime, Casap operates with a culture that explicitly emphasizes "building with intention, speed, and heart." The company deeply understands that in heavily regulated fintech environments, trust is absolutely paramount, and speed without safety is a nonstarter. The team is exceptionally ambitious yet fundamentally kind, focusing their collective energy on solving some of the hardest, most nuanced problems in the payments ecosystem. The founders, Shanthi Shanmugam and Saisi Peter, bring deep technical and product expertise to the table, fostering an environment where engineers and product managers are actively encouraged to tackle deep complexity with profound empathy and rigorous technical standards.

They operate in a structured hybrid model, requiring team members to be in the office three days a week in either their San Francisco or New York locations. This in-person requirement is not arbitrary; it is designed to ensure close collaboration, high-bandwidth communication during complex system design discussions, and the rapid iteration cycles necessary for early-stage product development. The atmosphere is one of intellectual honesty, where team members are expected to challenge assumptions, debate technical trade-offs openly, and ultimately commit to the best path forward. Empathy extends beyond the internal team to the end consumer, recognizing that behind every dispute is a real person who may be experiencing financial distress or confusion, making the accuracy and fairness of Casap's automated decisions critically important.

What You'll Actually Do

At Casap, engineers and product managers are tasked with building the definitive intelligence layer for post-transaction risk from the ground up. As a Backend Engineer, you will be responsible for developing and maintaining highly reliable, scalable backend systems. This involves integrating directly with legacy credit card mainframes, modern banking cores, and various merchant platforms to create a comprehensive, end-to-end workflow for chargeback management. You will architect robust patterns for microservices, primarily utilizing Go or Java, and scale the system to ensure it is highly configurable for different institutional clients with varying risk appetites and compliance requirements. Engineers must be adept at handling high-throughput, low-latency transaction data, dealing with complex concepts like idempotency, distributed locks, and eventual consistency in a financial context where dropped data or double-counting is unacceptable.

Product managers at Casap will define and scale AI-powered risk and fraud solutions, working in tight lockstep with the engineering and machine learning teams. You will deploy features that automate the entire lifecycle of a dispute—from the initial intake of customer claims to automated evidence collection from merchants, outcome prediction using advanced models, and the automatic filing of chargebacks with major card networks like Visa and Mastercard. You will be actively involved in creating and refining a proprietary dataset focused specifically on transaction fraud patterns, contributing directly to the ultimate vision of a real-time scoring engine for first-party fraud. This requires a delicate balance of optimizing for high automation rates while strictly managing false positives and false negatives to ensure regulatory compliance and maintain consumer trust.

Compensation & Benefits

Casap offers a highly competitive compensation package that is continuously benchmarked against real-time market data for top-tier venture-backed startups. The compensation philosophy is designed to attract and retain exceptional talent who are motivated by both immediate financial stability and long-term upside. The base salary range for a Senior/Staff Backend Engineer is confidently sourced at $170,000 to $220,000 per year. While specific salary data for Product Management and Data roles is currently unknown, candidates can expect these figures to be highly competitive and commensurate with the strategic importance of these positions to the company's core mission.

In addition to strong base pay, Casap provides significant equity grants for all full-time roles, offering employees a meaningful ownership stake in a rapidly growing Series A company tackling a massive market opportunity. The benefits package is exceptionally comprehensive, designed to support the holistic well-being and financial security of the team. This includes premium health, dental, and vision insurance coverage, a robust pension or 401(k) plan to support long-term financial planning, and generous paid time off policies to ensure employees can recharge. Furthermore, Casap offers structured bonuses and commission plans for applicable roles, aligning individual performance directly with the company's commercial success. The organization is deeply committed to supporting workplace diversity and creating an inclusive environment where all employees have the resources they need to thrive both personally and professionally.

The Interview Process

The interview process at Casap is deliberately rigorous and carefully designed to assess both deep technical capabilities and alignment with the company's core cultural values. For engineering roles, candidates can expect an initial phone screening with a recruiter or hiring manager to discuss their background, career aspirations, and mutual fit. This is typically followed by a series of technical assessments that rigorously test problem-solving skills, algorithmic thinking, data structures, and practical coding abilities. Given the complexity of the domain, system design interviews are a critical component of the evaluation process. Candidates will be asked to architect highly available, fault-tolerant systems, often simulating the real-world challenges of processing financial transactions or detecting fraud at scale.

Because Casap operates on a hybrid model, the interview process is typically a mix of virtual and in-person sessions, culminating in an on-site loop where candidates can meet the team, experience the office environment, and engage in collaborative whiteboarding sessions. Candidates should be well-prepared to discuss their hands-on experience with Go or Java, their philosophy on microservices architecture, and their proven ability to mentor junior team members and elevate the engineering culture. Behavioral interviews focus heavily on demonstrating empathy, extreme ownership, and the ability to thrive in a fast-paced, ambiguous environment. The process is generally described by past candidates as friendly, professional, and intellectually stimulating, with a strong emphasis on mutual evaluation—ensuring that the candidate is as excited about Casap as Casap is about them.

Why Join / Why Not

Why Join: If you are deeply excited by the prospect of having real, measurable impact, tackling profound technical complexity, and contributing to a mission that genuinely matters, Casap is an exceptional place to build your career. You will be joining a well-capitalized Series A startup that has demonstrated incredible product-market fit, backed by top-tier, high-conviction investors like Emergence Capital and Lightspeed Venture Partners. The total addressable market is massive, and the opportunity to build a category-defining product in the fintech space—specifically solving a $100 billion problem that plagues every major financial institution—is immense. The leadership team is highly experienced, transparent, and intensely supportive, providing a strong, stable foundation for rapid career growth and skill acquisition.

Why Not: Casap is a fast-paced, high-expectations startup operating in a highly regulated, high-stakes industry. This means the pressure to deliver compliance-grade, flawless results at significant scale is constant. The hybrid work model strictly requires being in the office three days a week in either San Francisco or New York, which may not suit those who prefer or require fully remote opportunities. Additionally, as a rapidly growing early-stage startup, the operating environment can be highly dynamic and occasionally chaotic, requiring a high degree of adaptability, resilience, and the willingness to wear multiple hats outside of your core job description. If you prefer highly structured, predictable enterprise environments with slow iteration cycles, Casap will likely not be the right fit for you.
