O projekcie: About the Role We’re building the AI-powered field sales platform — route optimization, territory management, CRM sync, and a mobile app that reps actually use every day. Where we’re heading: intelligent visit prioritization, natural-language CRM queries, automated call summaries, and predictive territory insights. You’ll help shape what these features look like and build them end-to-end, from LLM integration on the backend to the UX on mobile and web. This is not a “write code in isolation” role. You’ll be working alongside AI coding agents daily to move at the pace of a team twice our size. We need someone who treats AI tooling as a multiplier, not a novelty. AI-Augmented Development (must-have) - Active, daily use of AI coding tools (Claude Code, Cursor, Copilot, Aider, or similar) — not just autocomplete, but agent-driven development: multi-file edits, code generation from specs, test scaffolding, debugging - Ability to review and correct AI-generated code — you catch the subtle bugs, missing edge cases, and architectural drift that agents introduce - Experience prompting effectively — you know how to scope tasks, provide context, and iterate with an AI agent to get production-quality output Working Style (must-have) - You default to the smallest correct change. No speculative abstractions, no over-engineering - You can context-switch across mobile, web, and backend in the same day - You’re comfortable as an early engineer — high ownership, low ceremony, direct access to the founder Domain Knowledge (optional but preferred) - Salesforce integration — REST API, SOQL, CDC (Change Data Capture), OAuth flows, custom objects. Our system is a bidirectional Salesforce sync layer; - Geospatial systems — territory polygons, geocoding, PostGIS, mapping libraries (MapLibre, OpenLayers, Google Maps SDK) - Multi-tenant SaaS — RLS patterns, tenant isolation, data migration strategies - Field sales / CRM workflows — understanding what a rep’s day looks like, route optimization, visit tracking, lead prioritization Logistics - Direct report to the founder - You’ll have significant influence over architecture, tooling, and product direction - Best needed Hardware provided - Flexible hours, fully async — we care about output, not hours logged Wymagania: Engineering (must-have) - 5+ years shipping production software across web and mobile - Strong in TypeScript/React and Python — not dabbling, building real systems - Experience with React Native or willingness to ramp fast with AI assistance - Solid understanding of relational databases — schema design, migrations, PostGIS is a bonus - Comfortable owning backend APIs end-to-end: auth, data modeling, integrations, background jobs - Practical knowledge of cloud infrastructure — GCP preferred, but AWS/Azure experience transfers. - If you’re strong in most of this and ready to pick up the rest, apply. We’d rather hire someone sharp and adaptable than someone who checks every box but ships slowly. What We’re NOT Looking For - Engineers who need a ticket broken into subtasks before they start - Engineers who aren’t interested in integrating AI tools into their daily workflow - “Backend only” or “frontend only” specialists who won’t cross the boundary - Perfectionists who over-engineer at the expense of shipping Codzienne zadania: - Mobile app (React Native / Expo) — GPS tracking, route optimization, offline-first sync (PowerSync) - Web admin dashboard — territory management, data visualization - Backend API (FastAPI) - Infrastructure (GCP) — staging and production environments, CI/CD

Nasze wymagania: 7+ years of experience building and shipping production systems as a full-stack engineer Strong backend expertise in Node.js and TypeScript — not just building APIs, but designing systems that stay correct under load and failure Strong frontend skills with React, including the ability to build polished, production-ready product interfaces without depending on a separate frontend team Solid understanding of distributed systems: consistency, state transitions, concurrency, retries, failure handling, and eventual consistency trade-offs Proven experience building stateful, event-driven systems where correctness matters Hands-on experience with AWS in production, especially Lambda, API Gateway, SQS/SNS, EventBridge, IAM, CloudWatch, RDS, and serverless architecture patterns Strong experience with Infrastructure as Code, ideally AWS SAM and CloudFormation Strong PostgreSQL skills, including schema design, transactions, indexing, migrations, and performance tuning Experience designing systems with idempotency, auditability, and deterministic execution built in from the start Ability to debug and stabilize production systems end-to-end — across application code, infrastructure, data, and runtime behavior Strong grasp of observability, monitoring, logging, alerting, and incident response Good judgment around security, reliability, and cloud cost, with the ability to make pragmatic architectural trade-offs Ability and willingness to own features end-to-end — from product shaping to implementation, deployment, and post-release accountability Comfortable operating in a high-trust, high-autonomy environment with very little hand-holding Strong product and engineering judgment — you ask the right questions early, and you do not need heavy process to move fast responsibly Comfortable using LLMs, coding agents, and modern AI tooling as part of your development workflow Fluent English and Polish, written and spoken Mile widziane: Experience in payments, fintech, ledgering, settlement, or transactional systems Experience with document workflows, approvals, or multi-party business processes Experience working on systems of record or products with strict audit/compliance expectations Experience at an early-stage startup or in a small, high-talent engineering team Experience building products where reliability and system correctness matter more than shipping surface-level features O projekcie: You will own features end-to-end — from the React component a merchant clicks to the Lambda function that settles their transaction to the AWS infrastructure that keeps it all standing. No handoffs between "front" and "back". No waiting for someone else to unblock you. This is a high-trust, high-autonomy role. You'll work directly with the founding team, your decisions will ship to production fast, and yes — you'll be on the hook when something breaks. We're not looking for someone to fill a seat. We're looking for an engineer who gets it — who sees a distributed system and immediately starts asking the right questions about state, consistency, and failure modes. Someone who ships and takes pride in what they ship. Zakres obowiązków: Design and ship full-stack features across payments, document workflows, and agent orchestration Build and maintain stateful systems that demand idempotency, auditability, and safe retry logic Own AWS infrastructure — architecture decisions, serverless systems, IaC (SAM / CloudFormation), monitoring, cost, and security Work with PostgreSQL-backed services and event-driven components Use modern AI tooling (LLMs and coding agents) to accelerate development and experimentation Oferujemy: Competitive B2B compensation based on experience Equity — own a piece of what you build Fully remote work in an async-first environment Direct collaboration with the founding team High autonomy and fast decision-making Small team, outsized impact Work on technology that is genuinely novel End-to-end ownership across product, systems, and production Protocols don’t get built by committees. They get built by small teams who understood the problem before anyone else did
