INTRODUCTION
You're the technical leader for Internal Tools, owning architecture, quality, and engineering standards for the tools our internal teams rely on every day. This isn't a maintenance role. You'll bring recommendation, ranking, and other data-driven techniques to bear on how our tools work, and push for smarter automation wherever it saves people time. We're looking for someone adept in AI-collaborative development who can define the right problems and balance human and technology intelligence to solve them thoughtfully. You'll work directly with the Engineering Manager, who brings product requirements and technical vision; you turn them into specs, system designs, and implementation plans. You're the team's top technical voice while also being a high-output IC. Expect roughly a 80/20 split between hands-on coding and technical leadership.
Responsibilities
- Own technical direction for Internal Tools, including front-end architecture and component/design system strategy, and turn product requirements into technical designs and engineering tickets
- Design and build new internal tools and admin features end-to-end, front-end through back-end
- Find opportunities to apply recommendation, ranking, and search techniques to our tools, partnering with data science and product to set priorities
- Drive down technical debt through targeted refactors and set engineering standards through design reviews
- Build reusable components and tooling that pay off beyond a single project
- Be the escalation point for deep debugging, and partner with security to keep admin interfaces locked down
- Help engineers grow through pairing, code review, and direct feedback; write the specs and docs that let the team build with confidence
QUALIFICATIONS
- 5+ years building software, with a track record of shipping systems that scale
- Strong system design and architecture skills
- Extensive experience in JavaScript/TypeScript and Node.js
- Advanced, production-grade React skills
- Hands-on with PostgreSQL, MongoDB, or Elasticsearch, including performance tuning
- Experience building and scaling backend systems, ideally at a startup or small company
- Track record of mentoring engineers
WHAT SETS YOU APART
- Production experience with Next.js
- Experience with recommendation, ranking, or search systems
- Product-minded: you think about users, not just systems
- Background building internal tools or ops platforms
- Comfortable with cloud infrastructure, Docker/Kubernetes, and CI/CD
- Familiar with prompt engineering, fine-tuning, or shipping ML in production
We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses and identifying potential inconsistencies or verification signals in application materials based on available information. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.

Mid Level Full Stack Engineer Jobs: Frequently Asked Questions
How do I get a mid level full stack engineer job?
Position your experience around ownership, not just contribution. Hiring managers at this level want to see features or projects you drove from design to deployment, decisions you made independently, and results you can point to. Tailor your resume to show full stack depth on both sides of the stack, and be ready to discuss tradeoffs you navigated, not just code you wrote.
Which companies hire mid level full stack engineers?
Companies hiring mid level full stack engineers right now include Citi, JPMorganChase, and Apple, based on current listings on Migrate Mate as of August 2026. Hiring at this level comes from a wide range of employers, including high-growth startups that need engineers who can operate with autonomy and established organizations scaling product teams.
Are there remote mid level full stack engineer jobs?
Yes, remote and hybrid options are common at this level. About 35% of mid level full stack engineer openings are remote or hybrid as of August 2026, reflecting how broadly distributed engineering teams have become. Fully on-site roles still exist, particularly at companies that prioritize in-person collaboration for product and platform work.
How do I move up to a mid level full stack engineer role?
The path from entry level to mid level comes down to depth and demonstrated ownership over time. Build fluency across the full stack, not just your comfort zone, and look for opportunities to take a feature from requirements to production on your own. Consistent delivery, the ability to unblock yourself, and a habit of improving the codebase beyond your assigned tickets are what engineers and managers look for when evaluating readiness for mid level.
Which industries hire the most mid level full stack engineers?
Mid Level full stack engineer roles concentrate in Technology & Software, Banking & Financial Services, and Investment & Asset Management, based on current listings on Migrate Mate as of August 2026.
