Job Description

Full Stack Developer (AINative) 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 cloudbased contractor management platform automates the previously manual review of paperbased vendor cost reports, and our anomaly detection engine ensures 100% contract compliance and the elimination of overbilling. We move at a pace that much larger teams cant 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 different We''re not hiring developers to push tickets through a backlog. We''re hiring fulltime 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 200person 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 egofree 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 nonnegotiable Transparency and honesty in how we work and what we ship Driving and enabling value for clients, prospects, and teammates Relationship building and followthrough, both internally and with customers Relentless attention to improvement The Opportunity You''ll take ownership of meaningful slices of the product endtoend. You''ll design, develop, and ship secure, scalable web applications on AWS, and you''ll do it using the best AIassisted 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 sixperson team and a threeweek estimation cycle to get moving Your Responsibilities Backend Development Design and build robust serverside applications, business logic, and data processing pipelines Write efficient, scalable, secure code Optimize database queries and application performance Implement RESTful APIs and integrate with thirdparty services Frontend Development Build responsive, intuitive interfaces using modern frameworks (React preferred) Translate designs into interactive pages with strong usability and UX Ensure crossbrowser 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, faulttolerant architecture using ELB, Auto Scaling, Route 53 Monitor and optimize performance, scalability, and costefficiency Apply IAM and AWS security best practices in everything you ship AINative 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 AIgenerated 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 with different configurations and workflows Recognize when an AI tool is about to cross a privacy or security line and act accordingly Collaboration and Communication Work closely with our Engineering Lead and the rest of the engineering team Participate in code reviews, technical discussions, and knowledge sharing Communicate progress, blockers, and recommendations clearly and early Requirements Required 5+ years of professional fullstack development experience in production systems Handson AWS experience deploying, operating, and scaling real workloads. This is nonnegotiable; our entire platform runs on AWS. Strong proficiency in a modern backend language and a relational database Experience with React (or a comparable modern frontend framework), plus solid HTML/CSS/JavaScript fundamentals Active, recent experience using AIassisted development tools (Claude Code, Cursor, Copilot, agentic workflows) in real daytoday work Solid grasp of web security best practices A demonstrably curious, builderoriented mindset; you should be able to point to something you''ve built or shipped recently outside of your day job Bachelors degree in Computer Science, Engineering, or a related field, or equivalent demonstrated experience Preferred Experience with PHP and MySQL. This matches our current platform and will help you ramp faster, but it isn''t a hard requirement if your AWS and modernstack experience is strong. Prior experience on a small, highvelocity team Multitenant SaaS experience How we''ll evaluate A traditional interview loop won''t surface the right person. Expect a process that looks more like: A short conversation about what you''re building with AI right now, in your own time A practical exercise where you''ll work on a realshaped problem using your own AIassisted workflow; we want to see how you actually work, not how you perform A working session with our Engineering Lead and the engineering team If your instinct is to ask for a detailed spec before starting, this probably isn''t the right fit. If your instinct is to come back with something better than we asked for, it almost certainly is. Your Benefits Meaningful stock options : This is a small team, and the equity reflects it. We expect ownership, and we share the upside. Excellent medical, dental, and vision plans Real autonomy and real accountability Career growth in an earlystage company doing genuinely novel work New MacBook and accessories Location We''re looking for candidates based in Vancouver, BC or Calgary, AB.
