Salesfinity is rewriting how revenue teams prospect, call, and follow up. Our AI Parallel Dialer, built on NestJS and AWS, is already giving SDRs 5× more live conversations every morning—and we’re just warming up. Join a fast-growing crew that ships weekly, obsesses over customer outcomes, and believes the best products come from small, trusted teams who own everything they touch.

What you’ll own

Ship product, not tickets. Design, build, and release features end-to-end across our TypeScript/NestJS back-end and AWS infrastructure.
Scale what’s working. Harden our event-driven architecture to handle thousands of concurrent calls and real-time AI workflows.
Automate and observe. Champion DevOps best practices—IaC, CI/CD, metrics, and on-call—to keep releases boring and uptime boringly high.
Influence the roadmap. Work directly with founders, design, and GTM leads to turn ambiguous ideas into delightful product increments.
Mentor & multiply. Raise the technical bar through thoughtful code reviews, pairing, and sharing the “why,” not just the “how.”

Must-have experience

4+ years building production web / SaaS products, with deep expertise in TypeScript and modern back-end patterns (microservices, event queues, etc.).
Proven ownership of cloud-native systems on AWS (Lambda, ECS/Fargate, SQS/SNS, DynamoDB, CloudFormation/Terraform, or similar).
Strong DevOps mindset—automated testing, CI/CD pipelines, metrics, incident response, “you build it, you run it.”
Real-world MongoDB (or other NoSQL) data-modeling and performance tuning.
Track record of working in small, fast, trust-based teams where autonomy and accountability go hand-in-hand.
Excellent communication skills—you can explain trade-offs to both engineers and non-tech stakeholders.

Bonus points

Hands-on with NestJS, WebRTC, telephony, or AI/ML workloads.
Experience scaling high-throughput real-time systems (calls, chats, streaming).
Past startup or green-field product experience where you wore multiple hats.

What success looks like after 12 months

You’ve designed and launched at least two major product modules that customers rave about.
Deployment frequency is up, incident count is down, and observability dashboards make issues obvious before users notice.
The engineering team looks to you for architectural direction and mentoring.
You feel real ownership—celebrating wins with GTM, jumping on customer calls, and shaping Salesfinity’s technical vision.
