FDE — Forward Deployed Engineer
As AI commoditizes the skill of writing code, an engineer's true value is shifting from 'inside the screen' to 'solving real-world, physical-space problems.' FDE (Forward Deployed Engineer) is a development style where a highly-capable engineer embeds directly on the frontline and solves real business problems without a translation layer.
Where does engineer value head in the AI era?
As AI evolves, the skill of writing code itself is becoming a commodity. In an era where AI instantly prototypes from requirements, the true value of an engineer is shifting from 'inside the screen' to 'solving real-world, physical-space problems.'
In this shift, the Forward Deployed Engineer (FDE) role has drawn attention. AzabuSystem practices FDE in its purest form — embedding deeply on the frontline and validating systems in our own businesses as a proving ground.
1. The 'cognitive gap' in traditional software development
In traditional software development, 'those who define business requirements' and 'those who write code' are specialized roles. The real-world pains of the frontline inevitably get lost during the translation into specification documents. This 'cognitive gap' is the primary reason why unused features and systems that do not fit real operations are mass-produced.
2. The FDE approach — embedded on the frontline
To close this gap, the FDE role — popularized by US data analytics companies like Palantir — places highly-capable engineers directly on the client's frontline, sitting next to operators. Without a translation layer, they observe business processes themselves and translate them directly into systems — enabling fundamental problem-solving. It's a powerful approach especially for DX at large enterprises and government agencies with complex legacy systems.
3. How AzabuSystem practices FDE
AzabuSystem practices the FDE approach to the fullest. We don't just embed deeply on a client's frontline to solve problems — we also run our own real businesses, using them as a proving ground for next-generation systems.
For us, our own business (currently a beauty salon in Tokyo) serves as the 'laboratory' where we sharpen our FDE skills and validate next-generation systems.
Conventional contract dev vs. FDE
| Criteria | Conventional contract dev | FDE (AzabuSystem) |
|---|---|---|
| Positioning | External vendor (builds from specifications) | Insider embedded on the frontline (builds in the field) |
| Domain knowledge | Gathered via interviews and specification documents | Lived directly by embedding and observing daily operations |
| Development agility | Requires requirement definition, estimates, and sign-off | Observes on-site; same-day implementation & deploy |
| Target problem space | Problems that can be written into a specification | Real frontline pains, analog walls & UX improvements |
Three overwhelming strengths of FDE
① Complete domain knowledge from deep frontline immersion
An FDE embeds deeply on the frontline and lives the work right next to the operators. Without relying on interviews mediated by specification documents, we understand the field's rules and pains 100%. Not a millimeter of cognitive gap exists between the field and development.
② Zero-approval speed of validation
When development is mediated by a translation layer and approval process, even a single UI change takes time to coordinate. But an FDE working as one with the field can write code tonight for an error that happened on the floor today and deploy to production by the next morning to validate. AzabuSystem also uses its own businesses as a proving ground, producing real optimal solutions at this extraordinary velocity.
③ Engaging the 'analog walls' systems alone can't solve
Even a perfect system stalls on 'human emotion' and 'behavioral friction' in reality. An FDE does not run from the 'analog walls' at the boundary of digital and physical. Not by 'instruction,' but by improving UI/UX and adding nudges — we keep searching for the optimal answer to how people move, on the frontline of real business.
