Welcome to MFour
At MFour, we’re transforming how businesses understand consumers in an increasingly complex, AI-driven world. Founded in 2011, we are a leading consumer intelligence platform delivering validated, connected, and opt-in data that powers smarter, faster decision-making.
What sets us apart is our ability to connect what consumers say with what they actually do. Through our proprietary platform, MFour Studio™ and our flagship app Surveys On The Go®, we combine survey data with real-world behaviors, creating a complete, accurate view of the consumer journey.
We’re also shaping the future of research through innovations like DANI™, our AI-powered assistant that enables teams to quickly analyze data, uncover insights, and take action with confidence.
Built on our Fair Trade Data® model, everything we do is grounded in transparency, privacy, and trust. Today, we partner with leading global brands like Google, Microsoft, and Disney to eliminate blind spots and drive better business decisions.
At our core, we believe better data leads to better outcomes!
Your Journey to Success:
MFour is seeking a Staff / Principal Engineer to serve as the senior-most individual contributor on our Engineering team. This is not a team management role — it is the highest-leverage technical seat in the org. You will own the hardest cross-cutting technical problems across DANI and Studio, review critical code paths, and raise the engineering quality bar across every surface we ship. You are the voice on every architecture call that keeps us from making decisions we’ll regret in two years, and you own the areas of the codebase that AI coding tools cannot safely touch.
Your Mission:
Cross-Cutting Technical Ownership
- Resolve the hardest cross-cutting problems across DANI, Studio, and the data pipeline.
- Own critical code-path reviews — the final technical check on architecturally weighty decisions.
- Define and hold the engineering quality bar across all surfaces.
Hands-On Technical Contribution
- Write production code where judgment matters most and a wrong call compounds for months.
- Set and enforce standards for performance, security, and reliability across all teams.
Architecture Integrity
- Be the primary senior IC voice keeping system design, data models, and infrastructure ahead of feature pressure.
- Proactively retire technical debt before it threatens availability or velocity.
Platform Reliability & Incident Leadership
- Lead the highest-severity incidents, own post-mortems, and drive systemic fixes that retire each incident class for good.
- Partner with the VPs of Architecture and Engineering to turn roadmap direction into validated, executable plans.
AI-Era Engineering Practice
- Define where AI coding tools can be trusted and where human judgment is non-negotiable.
- Drive tooling, process, and CI/CD adoption that boosts velocity without sacrificing correctness or safety.
- Stay current on distributed systems, data platform engineering, and AI-assisted tooling to keep raising the bar.
- Set observability standards so the org can detect, diagnose, and resolve incidents faster.
Technical Mentorship & Knowledge Transfer
- Elevate engineers through code reviews, pairing, and direct feedback — without a management span of control.
- Document architectural decisions and standards so knowledge lives in the codebase, not in people's heads.
- Be a trusted IC peer to the VPs — the counterweight that keeps management decisions grounded in engineering reality.
What Sets You Apart
- 10+ years of software engineering experience with a clear track record of operating as a senior IC — Staff, Principal, or Distinguished Engineer level — in a high-growth SaaS or data platform environment.
- Deep, demonstrable command of distributed systems architecture, data pipeline design, and backend platform engineering — with the scars to prove it.
- Experience designing and reviewing systems that handle real-time data ingestion, identity resolution, and AI query layers at production scale.
- Proven ability to identify the boundaries of AI-assisted development and own the code paths that require irreplaceable human engineering judgment.
- Hands-on fluency with cloud infrastructure (AWS or GCP), observability tooling, and CI/CD — enough to own standards, not just consume them.
- A demonstrated ability to solve ambiguous, high-stakes technical problems without a playbook — and the intellectual honesty to say when a proposed solution is wrong.
- The technical credibility and communication clarity to be the most influential voice in any architecture room — without requiring a title to back it up.
In return for your dedication, we offer:
- Salary
- $175,000 - $200,000 DOE
- Health benefits
- Top-tier health benefits include: medical, dental, vision, LTD, and life insurance
- Mental health benefits
- Work-life balance
- Unlimited PTO
- Additional benefits
- In the WeWork office in the heart of the financial district in downtown Kansas City (KC LISTING ONLY)
- Open space concept & team-focused atmosphere
- Company-wide celebrations
- Team bonding events and happy hours
