Senior Full Stack Developer

Full-Stack Software Engineer (Agents & Rapid Prototyping)

Location: Remote (US-friendly hours)

Type: Full-time (founding/early engineer)

Team: Small, passionate, ego-free builders

We’re hunting for product–market fit
. That means we ship POCs fast, test hypotheses daily, and aren’t afraid to throw work away if the data says so. If you code for fun
, ask “
why
” before “
how
,” and love turning messy problems into scrappy automation that actually saves people time—this is your playground.

• Prototype at lightning speed: Build and ship POCs, internal tools, and production features in days—not weeks.
• Work with LLMs & SLMs: Integrate, evaluate, and fine‑tune models; design agentic workflows that reduce manual work.
• Automate the boring stuff: Sniff out bottlenecks, redundancies, and paper cuts; replace them with lightweight automations.
• Balance build vs. buy: Pragmatically choose off‑the‑shelf services vs. custom code; optimize for speed, cost, and learning.
• Own the stack end‑to‑end: APIs, data models, frontends, deployments, instrumentation, and on‑call for what you build.
• Collaborate without ego: Pair with design, product, and GTM to clarify the “why,” define thin slices, and ship continuously.
• Ruthlessly iterate: Be comfortable restarting weekly if needed; measure outcomes, not lines of code.

• 2–3 prod‑quality launches/month from idea → shipped.
• Clear learning loops
  : each release produces measurable signal (conversion, retention, time‑saved).
• Automation ROI: hours saved/team/week; decreased cycle time; reduced ops tickets.
• Agent impact: at least one agent in steady use by internal or pilot users within first 60 days.

• Have 4+ years building full‑stack products (or equivalent portfolio/hacker track record).
• Are fluent in a modern web stack (e.g.,
  Type Script/Node
  , Python
  , React/Next
  ; Postgres/Redis; REST/Graph
  
  QL).
• Have shipped LLM/SLM features (tool use, RAG, function calling, evals, latency/cost tuning).
• Can design simple, resilient backends; write clean, testable code; and deploy via CI/CD to a major cloud.
• Love debugging with data
  : logs, traces, metrics; you instrument before you guess.
• Communicate crisply, ask sharp questions, and default to action.
• Thrive in ambiguity; you don’t need a JIRA novella to start building.

• Vector DBs, embeddings, prompt/version management, offline evals.
• Agent frameworks (e.g., OpenAI tools, Lang Graph, custom planners/executors).
• Queueing/event systems (e.g., Kafka, SQS), Web Sockets, streaming.
• Security and privacy basics (authn/z, secrets, PII handling).
• Experience with low‑cost scrappy stacks (Cloudflare, Fly.io, Supabase, Firebase).

• FE: React/Next.js, Tailwind, tRPC/GraphQL
• BE: Node/Type Script and/or Python FastAPI
• Data: Postgres, Redis/Upstash, optional vector store
• Infra: Vercel/Fly.io/Cloudflare + Docker; CI/CD (Git Hub Actions)
• AI: OpenAI, Anthropic, local SLMs when useful; evaluation harness + prompt/version control

• Learn >
  Perfect: Ship thin slices, get signal, iterate.
• Write it down: Short RFCs → prototype → user feedback within days.
• Builder culture: No rockstars, no heroes—just ownership and curiosity.
• Time‑zone friendly: Async first; quick huddles when needed.

Competitive salary + meaningful equity. We optimize for ownership and impact
