SentiLink provides innovative identity and risk solutions, empowering institutions and individuals to transaction with confidence. We’re building the future of identity verification in the United States replacing a clunky, ineffective, and expensive status quo with solutions that are 10x faster, smarter, and more accurate.
We’ve seen tremendous traction and are growing extremely quickly. Our real-time APIs have helped verify hundreds of millions of identities, starting with financial services and rapidly expanding into new markets. SentiLink is backed by world-class investors including Craft Ventures, Andreessen Horowitz, NYCA, and Max Levchin.
We’ve earned recognition from TechCrunch, CNBC, Bloomberg, Forbes, Business Insider, PYMNTS, American Banker, LendIt, and have been named to the Forbes Fintech 50. We have also been named a 2026 FICO Industry Vanguard Decision Award Winner. Last but not least, we’ve even made history - we were the first company to go live with the eCBSV and testified before the United States House of Representatives on the future of identity.
SentiLink supports a variety of ways to work, ranging from fully remote to in-office. We operate as a digital-first company with strong collaboration across the U.S. and India. We maintain physical offices in Austin, San Francisco, New York City, Seattle, Los Angeles, and Chicago in the U.S., and in Gurugram (Delhi) and Bengaluru in India. If you’re located near one of these offices, we would love for you to spend time in the office regularly. Some roles are hybrid or in-office by design. For example, our engineering team in India works primarily from our Gurugram office.
Role:Are you a passionate software engineer who thrives on solving tough production problems, writing robust code, and making systems fast, reliable, and observable? We're looking for a Software Engineer to join our SRE team, where you'll work at the intersection of software and infrastructure, improving the reliability and performance of our most critical applications. This is a software engineering role at its core. You'll spend your time writing production code, profiling services, and debugging across the stack, with the leverage of knowing your work improves every service, not just one. You'll collaborate closely with backend and product teams to fix performance bottlenecks, chase down complex issues, and build tooling that supports better observability, cost-efficiency, and operational excellence. You'll also help improve our incident response processes, evolve our monitoring strategy, and contribute directly to high-impact production systems.
Responsibilities:Design, write, and ship production-grade code to fix bugs, improve performance, and increase reliability across multiple services.
Tackle complex coding challenges in live services — requiring solid understanding of algorithms, data structures, and system architecture.
Identify and resolve application issues by diving deep across the stack — including backend code, database interactions, and infrastructure components — with the ability to implement code-level fixes where needed.
Profile APIs and services under load to identify bottlenecks and implement fixes at the code, database, or configuration level.
Design and evaluate infrastructure solutions — weighing tradeoffs in architecture, tooling choices, and system configuration — and clearly document rationale for decisions made.
Collaborate effectively with US-based engineering teams, including availability for overlap hours in the late evening IST to support real-time coordination on incidents, design reviews, and cross-functional initiatives.
Communicate clearly and proactively — write structured updates, flag blockers early, and synthesize technical context for both engineering and non-engineering audiences.
Build tools, automation, and test frameworks to simulate traffic, validate behavior under stress, and prevent regressions.
Improve observability by contributing to logs, metrics, dashboards, alerts, and distributed tracing.
Collaborate on defining and measuring SLIs, SLOs, and SLAs to align reliability goals with business outcomes.
Contribute to the development and maintenance of incident response runbooks and help improve operational processes to minimize downtime.
Participate in incident response and root cause analysis and contribute to the engineering on-call rotation.
Support cost optimization efforts.
Research and evaluate new monitoring technologies or best practices to continuously improve system visibility and reliability.
7–8+ years of software development experience, with meaningful time in backend or SRE/infrastructure-adjacent roles.
Strong coding skills in languages such as Python, Go, or similar.
Proven ability to write and ship production code — and debug it under real-world conditions.
Deep understanding of PostgreSQL or similar relational databases, including performance tuning and query optimization.
Hands-on experience with distributed systems, containers (Docker), and Kubernetes in production — including making and defending architectural decisions, not just operating existing setups.
Experience with observability and monitoring platforms like Datadog, CloudWatch, or Prometheus.
Strong written and verbal communication skills — able to write clear technical proposals, postmortems, and async updates for distributed teams. Comfortable presenting tradeoffs and decisions to senior stakeholders.
Comfortable working with US-based counterparts, including regular overlap hours in the late evening IST.
Demonstrates a structured execution approach — breaks down ambiguous problems, tracks progress against milestones, and surfaces blockers before they become delays.
Knowledge of SLIs, SLOs, and SLAs, and how they align with business objectives.
Familiarity with cloud platforms (AWS preferred) and distributed systems.
Comfortable working across unfamiliar codebases and resolving issues from code to infrastructure.
Strong analytical, problem-solving, and collaboration skills.
Prior experience in an IaC (Terraform/Terragrunt) or performance engineering role is a plus.
Employer paid group health insurance for you and your dependents
401(k) plan with employer match (or equivalent for non US-based roles)
Flexible paid time off
Regular company-wide in-person events
Home office stipend, and more!

SentiLink Compensation & Benefits Highlights
-
Affordable Benefits — Healthcare is described as employer‑paid for medical, dental, and vision—often extending to dependents—reducing employee premium burden. Third‑party summaries also reference “fully covered” plans, indicating low out‑of‑pocket costs when accurate.
-
Parental & Family Support — Parental leave is advertised as fully paid (e.g., 14 weeks for birthing parents and 10 weeks for non‑birthing parents), alongside family medical leave and fertility benefits. This signals meaningful support for growing families.
-
Leave & Time Off Breadth — Time off is framed as generous, including PTO, paid holidays, paid sick days, and bereavement leave, with some roles noting flexible or unlimited PTO. Such breadth covers common personal and wellness needs.
SentiLink Insights
What We Do
SentiLink is the leading fraud intelligence company, providing financial institutions and fintechs with purpose-built solutions for identity verification and fraud prevention. Our products detect synthetic fraud, identity theft, and hard-to-detect first-party fraud in real time — helping partners stop losses before they happen while approving more legitimate customers. Founded in 2017 by Naftali Harris and Max Blumenfeld, creators of the risk and fraud systems at Affirm, SentiLink was built on a simple premise: to truly stop fraud, you have to deeply understand it. That belief shapes everything, from the expert human intelligence that feeds our models to the way we work with our partners. We don't call them clients or customers, we call them partners, because that's genuinely how we think of them. Today, SentiLink processes 3M+ identity verifications per day for 500+ financial institutions, including 13 of the top 15 U.S. banks and 50+ fintech unicorns. We've raised $85M from investors including Andreessen Horowitz, Craft Ventures, and NYCA Partners.
Why Work With Us
At SentiLink, deep understanding isn't just a value, it's a company-wide expectation. For example, our Revenue Accounting Manager can walk you through SSN windows. That's not an exception; that's the norm. You'll collaborate closely, move fast, and do work that genuinely matters.
