Forecasting, allocation, and professional identity remain fragmented across static tools and manual decision-making. Ando is rebuilding this system from first principles.\nWe start with highly accurate AI-generated demand forecasts, move to allocation-first labor optimization, and compound value through a persistent labor graph that captures skills, reliability, availability, and performance across time and employers. Over time, this becomes a professional identity layer and intelligent system serving both enterprises and frontline workers.\nAndo is a Seed-stage company backed by Slow Ventures and experienced operators. We are live with real customers and entering a phase where architectural clarity, learning loops, and AI systems quality are foundational to long-term success.\nAbout the Role\nWe're looking for a Senior Backend Engineer to own the core of our platform: a PostgreSQL data layer and Python/FastAPI services running on AWS. This role is heavy on database design and query performance, and heavy on AWS - you'll be building, running, and hardening the infrastructure our product depends on, not just writing application code. You'll shape the API contracts consumed by our Next.js web app and React Native mobile app, and help extend our AI/ML capabilities.\nThis is a startup role. We're looking for someone who can take a loosely-defined problem, figure out the right approach with minimal hand-holding, and drive it to done. You'll get real ownership and real ambiguity - ideally at the same time.\nWhat You'll Do\nPostgreSQL: Design PostgreSQL schemas, indexes, and queries for a growing, high-write scheduling and forecasting workload, and own performance troubleshooting (query plans, indexing strategy, migrations) at scale.\n\nAWS: Build, operate, and harden our AWS infrastructure - Lambda, RDS, App Runner, Bedrock - using Terraform, with an eye toward cost, reliability, and security.\n\nAI-assisted engineering: You use AI agents (Claude, Bedrock, MCP-based tooling) as a core part of how you write, test, and ship code daily - this isn't optional tooling, it's how the team works.\n\nDesign, build, and scale backend services in Python/FastAPI.\n\nOwn REST/OpenAPI contracts and generated clients shared across our Next.js (React/TypeScript) web app and Expo/React Native mobile app.\n\nExtend AI-assisted features using AWS Bedrock, Claude, and MCP (Model Context Protocol) integrations.\n\nCollaborate with data/ML on forecasting pipelines built with Prophet, Pandas, and NumPy.\n\nWrite and maintain pytest test suites and strengthen CI/CD gates in GitHub Actions.\n\nParticipate in architecture decisions (ADRs), code review, and mentor other engineers.\n\nPartner closely with product, mobile, and data teams to ship end-to-end features - often with only a rough spec to start from.\n\nWhat We're Looking For\n5+ years of professional backend engineering experience, including production Python (FastAPI, Flask, or Django).\n\nStrong PostgreSQL expertise: Deep, hands-on PostgreSQL experience - schema design, indexing, query optimization, and migrations in a production system, not just CRUD access.\n\nSolid AWS experience: Real ownership of AWS infrastructure - you've built and operated services on Lambda, RDS, and/or App Runner (or close equivalents), and are comfortable with IAM, networking, and cost trade-offs, ideally with Terraform.\n\nExperience designing, versioning, and documenting REST APIs (OpenAPI/Swagger) consumed by multiple client platforms.\n\nComfortable with containerized local development (Docker / Docker Compose).\n\nStartup mindset: A self-starter who works well independently and is genuinely comfortable with ambiguity - you don't need a fully-scoped ticket to make progress, and you're willing to make a call and adjust rather than wait for perfect clarity.\n\nStrong instincts for testing, code review, and pragmatic architecture trade-offs in a fast-moving product org.\n\nExcellent written communication - you document decisions and can work asynchronously.\n\nNice to Have\nExperience with ML/data tooling (Pandas, NumPy, time-series forecasting) or working alongside data science teams.\n\nExperience integrating LLM APIs or agentic tooling (Claude, Bedrock, MCP) into production products.\n\nFamiliarity with Next.js/React/TypeScript, enough to collaborate across the stack on API design.\n\nBackground in workforce management, scheduling, HR tech, or other vertical SaaS.\n\nPrior experience at an early-stage startup, where you owned infrastructure and data decisions with little existing precedent.\n\nExperience mentoring engineers or leading technical design for a small team.\n\nOur Stack\nDatabase: PostgreSQL (schema design, performance tuning, migrations) · Infrastructure: AWS - Lambda, RDS, App Runner, Bedrock - provisioned with Terraform · Backend: Python, FastAPI · Frontend: Next.js 15, React 19, TypeScript · Mobile: Expo, React Native · ML: Prophet, Pandas, NumPy · AI Tooling: Claude, AWS Bedrock, MCP integrations · Testing/CI: pytest, GitHub Actions\nCulture at Ando\nAndo is a high-trust, high-care organization built on ownership, respect, and thoughtful collaboration.\nWe value diverse perspectives, clear communication, and personal accountability. We move fast through alignment rather than force, operate comfortably in ambiguity, and build with empathy for the enterprises and workers our systems serve.\nThese values are core to how we work. Candidates who share them tend to thrive at Ando.\nEqual Employment Opportunity, DEI & Legal Notice\nAndo Technologies, Inc. is an equal opportunity employer.
