Software Engineer (Infra)

About Us Overjoy is building Sales AI for B2B commerce. Our mission is to enable 10x sales teams by bringing modern software and AI to a long-underserved industry: B2B sales for consumer brands. Over 500 modern brands like Tipsy Elves, P.F. Candle Co., and David Protein use Overjoy to find new prospects, run email marketing, manage accounts, and scale wholesale revenue — without the bloat of legacy platforms. We’re backed by Bessemer, OSV, Floodgate and founders of Thumbtack, Alloy, and Unsupervised — and 6 of our own customers invested after using the product. The Role We’re hiring a Software Engineer (Infrastructure) to own the systems, data pipelines, and infrastructure foundations that power Overjoy at scale. This is a high-leverage, foundational role focused on reliability, scalability, and data integrity. You’ll work closely with the founders and engineering team to design and operate data ingestion pipelines, background processing systems, and database infrastructure that everything else depends on. We grew 6x in 2025 and are aiming to do it again in 2026. As Overjoy scales usage across campaigns, automations, CRM, and integrations, this role ensures the platform remains fast, correct, and operable under growing load and complexity. What You’ll Work On
Own core data ingestion pipelines for search and CRM
Build scalable event processing and background job systems
Manage webhook ingestion at high throughput and bursty traffic
Establish observability, benchmarks, and monitoring for critical data paths
Stabilize database foundations and developer workflows
Design idempotency, replay, and backfill for failures and outages
Proactively identify and mitigate scalability risks for new launches
Improve backend developer experience through infrastructure and tooling You Might Be a Fit If You
Have experience building and owning backend or infrastructure systems in production

Background job systems and concurrency tuning Why Overjoy? Build for a real problem in a wildly underserved market Brand founders with multiple exits tell us, “I wish I had Overjoy when I launched my first brand.” We’re bringing modern software to a part of commerce that’s been overlooked for too long. AI that actually gets used daily This isn’t hype. Our customers use AI daily — to find leads, write emails, qualify prospects, and drive sales — often without even realizing it’s AI. You're joining the ground floor You’ll shape our architecture, product, and engineering culture from day one and define what Overjoy looks like for years to come. Our customers love us More than 5 of our customers have started agencies as a side business helping others how to use Overjoy. One joined our team full-time! We’re growing fast We’ve doubled revenue in the past 3 months and are on track to do it again. We're scaling quickly — and so will your impact. Why You Shouldn’t Join This isn’t a 9-to-5 job We’re doing hard things with a small team, and it’s intense. We won’t sugarcoat that. You’ll take full ownership and responsibility You won’t just execute. You’ll identify problems, shape solutions, and be accountable for what you build. That level of autonomy can be exciting, but also stressful — and it’s not for everyone. You’ll wear a lot of hats You’ll be expected to step outside of your lane — helping with support, onboarding, and product QA — often with little guidance. If you prefer clearly defined roles and boundaries, this might not be the right environment. Perks & Benefits
