Lantern | Software Engineers (Python, Full-Stack) | NYC (Onsite) | Full-time | withlantern.com

Lantern is building AI-powered revenue intelligence—autonomous agents that turn cold outreach into warm conversations. We detect buying signals across your tech stack, prioritize opportunities, and help B2B sales teams focus on deals that actually close. We're early, agentic-first, and moving fast.

Senior Software Engineer: You'll own complex technical problems end-to-end—translating customer needs into scalable architecture, optimizing AI model efficiency through prompt engineering, and shipping features that directly impact how revenue teams operate. We want bold ideas and people who push boundaries.

Junior Software Engineer: You'll work across our stack (Python, FastAPI, Next.js, React) alongside senior engineers, contributing to real features from day one. Great fit if you're hungry to learn, ship fast, and grow with a startup building cutting-edge agentic systems.

New Grad Software Engineer: Entry point for recent grads excited about AI and agentic systems. You'll get hands-on experience with our modern data stack (Postgres, ElasticSearch, ClickHouse, DuckDB), Kubernetes/AWS deployment, and Temporal.io workflow orchestration while shipping production code.

This role is based in our Manhattan office (4 days/week in-person). Full health and dental coverage.

VIVA Finance | Atlanta, GA (In Person)| Back-end Software Engineer

Target Experience Level: 2-4 years of professional software experience

VIVA is a Fintech Startup based in Atlanta, GA with the mission to build a more inclusive financial system. VIVA offers unsecured personal loans to customers who have traditionally been excluded and taken advantage of by legacy financial institutions. The VIVA difference is to underwrite heavily on employment history and set up repayments through voluntary direct deposit payments from the borrower's paycheck. Our interest rates are less than 1/3 of the rates our customers are able to get from other financing options.

We are a VC backed company and have been in business for 6 years. We have been profitable since mid 2024 and are dramatically ramping up origination volume in 2026. We are hiring an additional backend engineer to support the larger transaction volume, as well as to support new products we are launching to diversify our revenue stream (including automobile refinancing and a credit builder account). You will join our engineering team of 11 and work in a dynamic environment where you are frequently writing net new code to directly support business objectives.

Our tech stack for the back-end is fully on AWS, using Lambda and ECS for compute and Typescript as the language, but experience with this specific stack is not necessary for talented candidates. Our preference is candidates who can come in office 4 days a week to our office on the Atlanta Beltline (next to Krog Street Market). VIVA does not provide visa sponsorship, so please have authorization to work in the USA.

Send an introduction to our hiring manger (alexa@viva-finance.com) with a resume and we will be in touch!
