Who we're hiring and why

At Spekit, we’re building the next generation of AI systems that transform how people learn and work – and that starts with a powerful technical foundation.

As we scale our AI platform, we’re tackling increasingly complex challenges in data performance, modeling, and system design thinking. We’re looking for a Senior Full Stack Engineer with a specialization in database and systems performance to help us level up our architecture, strengthen performance across the stack, and mentor others in building fast, maintainable systems.

This role sits on a team focused on accelerating execution and delivering high-impact product experiences. We’re looking for someone who is a strong software engineer first, someone who brings clarity and systems thinking to every feature you design. With database and performance depth as their superpower, they’ll instinctively optimize queries, model data effectively, and design systems that scale gracefully. This Sr. Software Engineer will help us evolve how data flows across our platform, powering intelligent enablement at scale.

The Opportunity

As Spekit continues to grow, our engineering challenges have shifted from building features quickly to building them consistently and sustainably. We’ve accumulated multiple UIs connected to the same APIs, with ad-hoc implementations scattered across the stack. To continue moving fast without adding friction, we need a pragmatic, technically strong engineer who thrives in complex systems and knows how to bring clarity through structure.

This role is designed for a senior full-stack engineer who can both ship new features and improve the systems that power them. You’ll help us evolve our codebase, debug deeply, establish guidelines, and make the product experience consistent and performant.

By introducing this role, we aim to accelerate iteration speed, strengthen system design practices, and foster a debugging culture that helps the team move faster with confidence.
Must-Haves
Full-Stack Fluency: Demonstrated ability to deliver end-to-end features using React (frontend) and Django/Python (backend) with PostgreSQL.
Debugging as a Superpower: Systematic approach to identifying and resolving bugs across layers — from frontend quirks to API logic to data inconsistencies.
Modernization Mindset: Knows how to refactor incrementally and establish cleaner boundaries in legacy systems without halting delivery.
System & Design Pragmatism: Understands domain separation, modularity, and how to introduce reusable patterns where ad-hoc solutions once lived.
Collaborative Systems Thinker: Works transparently, communicates trade-offs clearly, and helps the team make thoughtful, fast decisions
Nice-to-Haves
CI/CD & Observability Familiarity: Comfortable improving dev pipelines, logs, metrics, and alerts to make debugging faster.
UX-Driven Approach: Empathy for user experience and design consistency, and comfort working closely with designers on pragmatic solutions.
Frontend Performance Awareness: Ability to diagnose rendering bottlenecks, bundle size issues, or component inefficiencies.
Experience Standardizing Codebases: Has introduced or enforced shared patterns, linting rules, or architecture guidelines in fast-paced teams.
Experience in Small/Scaling Startups: Comfort working close to production and DevOps boundaries.
Interest in Tooling: Enjoys improving developer experience — from better debugging utilities to simpler build processes.
What Success Looks Like
30 Days
Ramp up on Spekit’s codebase, deployment pipelines, and multi-UI architecture.
Ship at least one small end-to-end feature to demonstrate full-stack capability.
Identify key friction points in the debugging process and propose practical improvements.
60 Days
Deliver meaningful improvements in one or more areas: code reuse, observability, CI/CD, or performance.
Lead or document code guidelines that reduce ad-hoc duplication and clarify patterns.
Start influencing PR reviews and discussions, modeling clear trade-off reasoning.
90 Days
Lead the delivery of a feature or improvement that both ships user value and modernizes a legacy path.
Establish yourself as a go-to engineer for debugging and architectural clarity.
The team feels a noticeable lift in iteration speed and debugging confidence.
