Memorang | Product Engineers + Technical Project Manager | Full-Time | Los Angeles (or US remote for exceptional hires)

Help build the AI stack for education. Memorang gives teams the infrastructure to build, launch, and monetize AI-powered learning apps. We bootstrapped to profitability, were voted #1 among 1,500 in the Vercel AI Accelerator, and power products that collectively reach tens of millions of learners.

We’re hiring for two roles:

Product Engineers Own features from the first rough idea to production. You’ll work across AI workflows, backend systems, and user interfaces, making product decisions along the way. We’re looking for engineers who ask good questions, care about the details users notice, and can turn an ambiguous problem into something useful and shipped.

Stack: TypeScript, React/Next.js, React Native, Node.js, AWS Lambda, Postgres, and Neo4j.

Technical Project Manager Turn complex work into clear plans and keep delivery moving. You’ll coordinate across engineering, design, and customer needs, surface dependencies early, resolve blockers, and keep owners and timelines clear as priorities change.

Ideal background: an engineer who moved into project management, with startup experience and enough technical depth to discuss APIs, architecture, and AI workflows with the people building them.

Why join? A small team, meaningful ownership, and products used by millions. You’ll help shape what we build and how we work, with a short path from an idea to seeing it in users’ hands.

Remote-first, async-friendly, with health and wellness stipends, home-office support, and paid time off.

Apply: Email careers@memorang.com with your CV, a few sentences about what interests you, and something you’re proud to have built or delivered.

VIVA Finance | Atlanta, GA (In Person)| Front-End + Mobile Developer

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 the 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 7 years. We have been profitable since mid 2024. We are hiring an additional frontend engineer to support our increasing customer volume, support new products we plan to launch to diversify our revenue streams, and bring our mobile app to feature parity with the web. You will join our engineering team of 14 and work in a dynamic environment where you are frequently writing net new code to support business objectives.

Our tech stack for the front-end is fully hosted on AWS. The web app is in React and we are building a mobile app with React Native, 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!

AI x Healthcare Startup | bracehealth.com | Boston, MA Onsite | Full-time | Early Engineer

We're looking for a backend-leaning fullstack dev. You will be one of the first engineers outside of the founding team. Here is a bit more about us: We're a seed stage AI startup backed by top tier investors. We're on a mission to ensure every patient gets covered for the care they need and every doctor gets paid for the work they do.

We’re building deep, vertically integrated technology systems to solve fundamental problems in US healthcare - the biggest market in the world ($5T). We use AWS, K8s, React, and Rust but there is no requirement to have prior experience with them specifically. We'll teach you!

We are a founding team made up of ex-YC, Amazon, Meta, Microsoft, and Harvard Business School with previous successful exits.

You’ll own entire product areas and be expected to play a true full-stack role, with the ability to go from customer need to end-state product. You’ll work directly with the CTO at the edge of what's possible with LLMs and agentic systems applied to a hard domain. You'll contribute to technical strategy, make real architectural decisions, and write vast amounts of production code with AI first developer workflows. Most importantly, the technology you build will have real impact on real people - clinics staying open, clinicians getting paid, patients getting care.

This is an opportunity to work in a fast paced, high ownership environment while solving real problems in healthcare.

We're happy to share more details on the role in person/on zoom. Please fill out this form if interested!

Juro | AI Engineer (Agentic team) | London, UK | REMOTE (UK) | Full-time | £115k + equity

Juro is an AI contract automation platform used by in-house legal and business teams. Our Agentic team builds Operator, the agent that works across contracts inside Juro: it answers questions and takes action on legal data. You'd build the tools that let it act across the product, own parts of the agent harness (planning, tool use, context) and put evals around what you ship, together with our QA team.

Stack: TypeScript/Node.js, MongoDB, pgvector, AWS Bedrock, LiteLLM, Mastra, some React. Engineers pick their own AI tooling (Claude Code, Codex, Cursor...) and we pay for the usage.

We're looking for programmers first who now build with LLMs, and who have shipped something people use. Years of ML matter less to us than what you've built. We apply models, we don't train them.

Process: 30-min intro call, interview with the hiring manager, a build review where you walk us through something you've built, and a short chat with our CTO. We reply to every applicant.

You'll work from the UK. For exceptional candidates we can sponsor a UK Skilled Worker visa, whether you're relocating or already in the UK. If you need sponsorship, say so in your application.
