Job Description

1 - Architecture & System Design:

- Own the architecture on every project: the agents (LangGraph), the API (FastAPI), the database (Postgres) and the frontend (Next.js). You build phase one while keeping phase two and three in mind.

- Build every week, hands on the keyboard. Make the calls as you go: build or buy, new table or no new table, server or client, store it or compute it. The rest of the team builds on top of what you decide.

- Write data models and API contracts clean enough that a junior developer can extend them six months later without asking you a single question.

- Catch technical debt early and fix it with a plan, instead of at 2am with a hotfix.

2 - AI - Native Engineering: Our Proprietary System:

- Work inside Lecxe Compass, our proprietary engineering system: custom agent harnesses, deliberate context management, and evaluation loops built in - house. This is the difference between Engineered AI that is reliable and Generic AI that is merely fast.

- Build and lead a team of AI - native engineers. Teach them when to trust an agent, when it is confidently wrong, and when it has written code that passes every test but misses the point.

- Ship real AI features: multi - step agent pipelines, WhatsApp voice notes turned into clean data, documents read and understood automatically, and search over a company's own files that works in production, not just in a demo.

- Push Compass forward. What you learn on client work feeds straight back into the harnesses and the context layer, so you are building the system, not just using it.

3 - Design: Beautiful Products, Not Just Functional Ones:

- Own the visual and interaction design of what you build. Business owners and their staff use Lecxe products every morning, so they should feel considered, not generated. You know what good looks like, and you use it.

- Think in user flows before components. Before you open your IDE, you already know who's using this, what they're trying to do, and what friction you're removing.

- Set the design standard: component libraries, spacing systems, interaction patterns. A junior developer building a new screen should be able to follow your patterns without asking.

4 - Engineering Standards & Team Leadership:

- Set and enforce engineering standards across the team: code review, automated testing, deployment hygiene, observability, and security baseline. You are the bar.

- Run code reviews that teach, not just that fix. Your review comments make junior engineers better, not just compliant.

- Onboard new engineers to ship within their first week. Orient them on the codebase, the patterns, the tools and the culture, then get out of their way.

- Build the internal culture of how this team engineers: how we use our own tooling, how we review AI - generated code, how we decide when to trust the agent and when to override it.

5 - Communication: The Engineer Who Can Talk:

- Walk clients through what you built, why you built it that way, and what it means for their business. No jargon, no slides, no PM needed to translate.

- Write documentation that a non - engineer can read and a junior engineer can build from. Crisp, specific, and free of ambiguity.

- Communicate proactively when something is off - track: to the Senior PM, to the client, to your team. No one at Lecxe finds out about a problem from a client before they hear it from you.
