Arbi eliminates fragmented workflows, integrates directly with your ATS, and orchestrates AI agents for sourcing, outreach, screening, and candidate intelligence end-to-end. By combining reasoning-optimized models with deep workflow automation, Arbi helps talent teams win more top candidates with dramatically less friction.\nWe’re backed by top operators and investors, and we’re growing fast. Our momentum is further fueled by blue-chip partners and programs, including the NVIDIA Inception Program, the HPE Unleash AI Program, and our active DoD SBIR Phase II award and contract.\nWe’re now hiring a Founding Staff Software Engineer to help accelerate features on Arbi to help us dominate one of the largest and fastest-expanding categories in modern software.\nThis is not a maintenance role. This is a hands-on, high-ownership opportunity for someone who has operated at a staff engineer, architect, or founding/lead engineer level and knows how to build production-grade systems that scale. You will work on the backbone of our platform: APIs, orchestration systems, data workflows, search infrastructure, background jobs, cloud deployment, and backend systems that power AI-enabled products for real customers.\nThe Role\nWe’re hiring a Founding Staff Software Engineer to help us scale and evolve our core systems. You'll work closely with AI engineers, frontend devs, and product leads to build the APIs, services, and infrastructure powering our agentic workflows.\nThis is a hands-on role for someone who knows how to build enterprise-grade backends using modern Python/FastAPI stacks. You’ll lead major technical efforts, make architecture decisions that scale, and help us stay fast, reliable, and resilient as our user base grows.\nWhat You'll Do & Own\nDesign, build, and maintain

deployments, CI/CD pipelines, and backend infrastructure reliability\n\nSupport integrations, data pipelines, workflow automation, and asynchronous processing systems\n\nHelp define backend architecture, engineering standards, observability, and performance practices\n\nWork closely with product, AI, and frontend teams to deliver features that power B2B and B2C SaaS experiences\n\nMentor engineers and raise the bar on engineering quality, speed, and execution\n\nOperate like an owner in a startup environment, balancing speed with sound engineering judgment\n\nContribute to AI-enabled engineering workflows and modern developer tooling, including tools such as Cursor and/or Claude Code\n\nWho You Are\nStrong backend engineering experience with Python\n\nDeep hands-on experience with FastAPI\n\nStrong production experience with PostgreSQL and Redis\n\nExperience using OpenSearch\n\nHands-on experience with Celery and Temporal\n\nProven experience building robust REST

systems thinking, sound backend architecture judgment, and the ability to move from idea to production\n\nAbility and willingness to relocate to Northern VA/DC\n\nBonus Points\nHave built backend platforms that became the foundation for a growing product\n\nKnow how to balance speed, scale, reliability, and developer experience\n\nHave strong instincts around designing for maintainability, observability, and performanceEnjoy owning ambiguous problems and turning them into simple, durable systems\n\nCan mentor others while still being deeply hands-on\n\nAre excited by AI-enabled software development and modern engineering workflows\n\nWant to help shape both the codebase and the culture of an early-stage company\n\nExperience building AI-enabled products or backend systems that support AI workflows\n\nExperience with search-heavy, data-intensive, or workflow-centric products\n\nExperience in recruiting tech, HR tech, SaaS platforms, or decision-support systems\n\nExperience designing backend systems for multi-tenant SaaS environments\n\nExperience improving developer productivity using Cursor, Claude Code, or similar AI coding tools\n\nExperience with event-driven systems, job orchestration, and resilient distributed workflows\n\nExperience helping scale an early-stage engineering team\n\nExperience working directly with product and leadership in a founding-stage company\n\nWhat’s in It for You\nJoin a tight-knit engineering team shipping fast and building with ambition\n\nWork on products used by real-world recruiters, analysts, and
