Note: The job is a remote job and is open to candidates in USA. Fingerprint empowers enterprises to detect and stop online fraud through device intelligence and fraud detection technology. The Senior Backend Engineer will build, scale, and operate reliable Core API systems for real-time fraud detection, while owning service reliability, observability, performance, and production operations.
Responsibilities
- Design, develop, and optimize backend systems for real-time data processing and web services, with reliability, latency, and cost as first-class design constraints
- Define and own SLIs and SLOs for Core API services, and use error budgets to make concrete tradeoffs between shipping velocity and stability
- Build and maintain the observability that makes these systems debuggable: Meaningful metrics, structured logging, distributed tracing, and alerts that fire on user-visible symptoms rather than noise
- Participate in a shared on-call rotation, act as an effective responder during incidents, and lead blameless postmortems. The schedule will be communicated in advance, and we strive to balance coverage equitably while minimizing off-hours disruptions
- Drive down operational toil by automating recurring manual work, and close the loop on incident action items so the same failure doesn't happen twice
- Conduct capacity planning, load testing, and performance tuning to ensure the platform scales ahead of demand
- Conduct deep dives into problematic features, researching and analyzing their behavior to understand root causes and identify potential solutions. Develop hypotheses, run experiments, analyze results, and translate findings into actionable engineering improvements
- Work with cross-functional teams to integrate backend components with other services, ensuring performance and scalability
- Foster a data-driven, reliability-minded culture by sharing engineering best practices and collaborating on cross-functional projects
- Mentor other developers, helping all team members grow in our mission, values, and abilities
Skills
- * 5+ years of experience in backend development, including meaningful time operating what you built in production
- * Formal SRE practice experience — error budget policies, capacity models, production readiness reviews, chaos or fault-injection testing
- * Strong, demonstrated experience in GoLang and/or Node.js with a willingness to learn
- * Strong experience in designing, developing, and maintaining scalable backend systems
- * Experience with building and optimizing APIs, real-time data processing systems, and microservices architectures
- * Hands-on experience running production services on containerization and orchestration technologies such as Docker and Kubernetes
- * Experience with infrastructure-as-code tools like Terraform or AWS CloudFormation
- * Working fluency with observability tooling such as Datadog or comparable monitoring, logging, and tracing platforms — including instrumenting services and building useful dashboards and alerts
- * Experience participating in an on-call rotation: triaging live incidents, mitigating impact, and writing up what happened afterward
- * Strong knowledge of SQL and experience with databases like DynamoDB, Redis, or Elasticsearch
- * Proficiency with general software engineering tools: Git, IDEs, shell scripting, CI/CD
- * Proficient in English for clear communication in a global, remote team
- * Ability to work independently on tasks while effectively collaborating as a team member
- * A strong desire to mentor and grow junior team members
- * BS/MS in Computer Science or a related field, or equivalent work experience
- * Practical experience with analytical storage systems like ClickHouse, Snowflake, BigQuery, Redshift, or Databricks
- * Experience with performance profiling and cost optimization of high-throughput cloud workloads
- * Experience working with large open-source projects to address the needs of a wide variety of stakeholders, and demonstrated ability to work and communicate asynchronously across a world-wide team
- * Demonstrated experience with both Node.js and Go in a backend context
- * Excellent understanding of Internet security & privacy mechanisms
- * Backend development: Golang and NodeJS (Preferred), TypeScript, Express or equivalent
- * Infrastructure and delivery: AWS, Terraform, Docker, Kubernetes, CI/CD pipelines
- * Observability: Datadog, metrics/logging/tracing
- * Data analytics/processing: ClickHouse, dbt
- Due to regulatory and security reasons, there's a small number of countries where we cannot have Fingerprint teammates based. Additionally, because Fingerprint is an all-remote company and people can join our workforce from almost any country, we do not sponsor visas. Fingerprint teammates need to be authorized to work from their home location
Benefits
- 100% remote work
