• Own backend technical leadership: architecture, code quality, delivery plan, and hands-on implementation for the SAR area-based modules. • Design and implement REST APIs and service-oriented backend components. • Ensure robust observability: • Log key operations, including geospatial calculations and user actions. • Build production-grade metrics (Prometheus/Grafana or equivalent). • Drive performance and reliability engineering, including preparation and execution of load/stress testing up to 3,000 simultaneous connections. • Align the backend with security/traceability needs (auditability, immutable action history, etc.) and support integrations that rely on GOV.ID / QES / BankID (working with stakeholders that provide tokens/certificates). • Coordinate technical work with the project working group, and contribute to inception-stage outputs (detailed business processes + technical design) before implementation. • Contribute to delivery and handover: deployment support, documentation, and warranty period collaboration through rollout support.

• Build greenfield projects while continuously evolving existing systems • Design and implement microservice-based architectures • Maintain a strong focus on system quality, reliability, and performance • Contribute to technical decisions and feature planning • Write and review technical designs, proactively identifying areas for improvement • Stay up to date with modern technologies and incorporate them into everyday work • Collaborate closely with teammates in a remote but highly synchronous environment

About Vertex Vertex is a high-growth enterprise software company powering real-time, cloud-native 3D applications for the world’s most advanced manufacturers. Our platform enables Fortune 500 industrial and defense-adjacent organizations to deploy scalable, highly performant 3D-enabled workflows in secure AWS environments, including GovCloud. We operate at the intersection of cloud infrastructure, enterprise engineering systems, and mission-critical deployments. As Vertex scales and expands into complex enterprise programs, operational excellence and deployment reliability are critical to our success. The Role Vertex is seeking a Senior Software Engineer – Cloud to design and evolve the core backend services powering our enterprise 3D collaboration platform. You will: - Architect and scale distributed cloud services that support mission-critical enterprise deployments - Lead scalable and optimized backend design decisions across APIs, data stores, messaging systems, and microservices - Drive engineering quality, observability, and reliability standards - Contribute to long-term platform evolution, not just short-term delivery This role is ideal for an experienced backend engineer who thinks in systems, understands the trade-offs of distributed architecture, and takes ownership of platform performance and reliability in production AWS environments. Reporting Structure - Reports to: VP of Product & Engineering What You Will Own - Architect, design, and implement scalable backend services supporting high-volume API consumers and enterprise workloads - Lead evolution of our cloud-native platform architecture across compute, storage, messaging, and observability layers - Drive performance optimization across services, APIs, and data stores - Ensure services are production-grade, fault-tolerant, and observable - Contribute to infrastructure design decisions in partnership with DevOps and platform engineers - Balance performance, cost, scalability, and maintainability in architectural decisions - Establish and enforce strong testing practices, including automation and integration coverage - Participate in technical design reviews and provide thoughtful, high-quality code reviews - Proactively identify architectural risks and propose durable solutions What You Need to Succeed - 5+ years of experience building SaaS products in cloud-native, microservices-based architectures - Strong backend development experience in Scala, Java, or similar JVM-based technologies - Experience designing and operating distributed systems in production - Hands-on experience with AWS or Azure production environments - Deep understanding of REST API design, performance optimization, and developer experience - Experience working with containerized workloads (Docker) - Strong understanding of data modeling, database interactions, and scalability patterns - Experience managing mission-critical or sensitive production systems - Familiarity with observability best practices (metrics, logging, tracing) - Strong architectural judgment and ability to reason about tradeoffs - Excellent written and verbal communication skills in a remote environment - Experience working remotely as part of a distributed team What Will Set You Apart - Background architecting enterprise B2B SaaS platforms - Direct exposure to GovCloud or regulated environments (SOC2, FedRAMP, CMMC) - Experience building distributed systems using Akka (actors, clustering, persistence, or streams) - Familiarity with event-driven systems and streaming architectures (e.g.,Kafka / MSK, SNS/SQS) - Proficiency with Infrastructure as Code (CDK / CloudFormation) - Demonstrated ability to optimize large-scale API ecosystems - Experience implementing frontend/full stack web applications leveraging modern frameworks and patterns - Familiarity with 3D visualization, CAD, PLM, or industrial systems - Experience improving developer experience for external API consumers - Working knowledge of instrumentation and telemetry patterns targeting Datadog, New Relic, etc. Our Technology Stack - AWS-native architecture (Fargate, S3, MSK, RDS, Postgres, Redis, Elasticsearch) - Infrastructure as Code (CDK / CloudFormation) - Containerized services (Docker) - Observability via Datadog and CloudWatch - Backend services in Java, Scala, Python, Node, C++ - Frontend SDKs in TypeScript, React, NextJS, VueJS Why This Role Matters As Vertex expands into larger enterprise and defense-adjacent programs, backend platform reliability and performance become foundational. This role ensures: - Scalable architecture that supports enterprise-grade deployments - Durable API design across diverse integration environments - Performance optimization across real-time collaboration workloads - Reduced operational risk through strong engineering discipline - A backend platform that can scale with Vertex’s growth This is a high-impact role for an engineer who wants architectural influence, production ownership, and the opportunity to shape the long-term evolution of a growing cloud platform. Location This position is 100% remote (United States) Why Join Vertex - High-margin, rapidly growing enterprise SaaS company - Meaningful technical ownership - Flexible remote culture - Competitive compensation and benefits - Opportunity to grow into Staff or Principal-level platform leadership If you are a cloud-native backend engineer who enjoys building distributed systems at scale — and want to help architect the platform powering enterprise 3D collaboration — we’d love to talk.
