Full Stack Developer (AI-Native)

Full Stack Developer (AI-Native)Join Our Team & Help Reinvent Industrial Operations PayShepherd is a vertical SaaS company transforming how heavy industries, such as Oil and Gas, Pulp and Paper, Mining and Power Generation, manage contractor spend. Our cloud-based contractor management platform automates the previously manual review of paper-based vendor cost reports, and our anomaly detection engine ensures 100% contract compliance and the elimination of overbilling. We have real customers, and a genuine moat. We move at a pace that much larger teams can't match, and we're looking for developers who want a real stake in the work, with the ownership and equity to match. Why this role is differentWe're not hiring developers to push tickets through a backlog. We're hiring full-time developers who are already living in the new way of building software by pairing with Claude Code, running agentic workflows, and shipping at multiples of the old pace without sacrificing quality. Every engineer matters disproportionately. The traditional separation between "designer," "PM," and "engineer" is collapsing, and we want people who feel that collapse as an opportunity, not a threat. You'll work alongside our Engineering Lead and the rest of a tight engineering group, with a meaningful stock option grant that reflects the level of ownership we expect. If you want to be a name on a 200-person org chart, this isn't it. If you want a real stake in what gets built and where it goes, read on. What we value- Urgency and initiative: moving things forward without waiting to be told- Ownership and commitment: you treat this like it's yours, because it is- Humility and ego-free collaboration: strong opinions, loosely held; quick to be wrong; quicker to learn- Hard work in service of clear, measurable goals: output, not theatre- Genuine curiosity about what's now possible with AI: paired with the discipline to know when AI output is wrong and push back on it- Care for security, privacy, and boundaries: our customers trust us with sensitive financial data, and that trust is non-negotiable- Transparency and honesty in how we work and what we ship- Driving and enabling value for clients, prospects, and teammates- Relationship building and follow-through, both internally and with customers- Relentless attention to improvement The OpportunityYou'll take ownership of meaningful slices of the product end-to-end. You'll design, develop, and ship secure, scalable web applications on AWS, and you'll do it using the best AI-assisted tooling available. This role suits someone who- Has shipped real production code in real systems with real consequences- Is already using Claude Code or similar tools in their daily workflow, not just experimenting on weekends- Knows when to trust AI output and when to validate, push back, and iterate- Cares about how the product feels for the user, not just whether it works- Treats security as a feature, not a checkbox- Doesn't need a six-person team and a three-week estimation cycle to get moving Your ResponsibilitiesBackend Development- Design and build robust server-side applications, business logic, and data processing pipelines- Write efficient, scalable, secure code- Optimize database queries and application performance- Implement RESTful APIs and integrate with third-party services Front-end Development- Build responsive, intuitive interfaces using modern frameworks (React preferred)- Translate designs into interactive pages with strong usability and UX- Ensure cross-browser compatibility and adherence to web standards Database Management- Design, optimize, and maintain relational databases (MySQL in our current stack)- Implement schemas, indexes, and relationships that protect data integrity and performance- Perform migrations, backups, and data migration tasks as required AWS Cloud Infrastructure- Deploy, configure, and operate applications and services on AWS (EC2, RDS, S3, Lambda, ALB, and others)- Build scalable, fault-tolerant architecture using ELB, Auto Scaling, Route 53- Monitor and optimize performance, scalability, and cost-efficiency- Apply IAM and AWS security best practices in everything you ship AI-Native Development- Use Claude Code (or equivalent agentic tools) as a core part of your workflow, not as a novelty- Parallelize work across multiple AI workstreams where it genuinely accelerates output- Develop the judgment to validate AI-generated code, recognize when it's wrong, and iterate to a correct result- Share patterns, prompts, and learnings with the team, as we are all levelling up together Security and Boundaries- Apply web security best practices throughout development: input validation, authn/authz, secrets management, dependency hygiene- Be thoughtful about blast radius: changes can ripple across clients
