Senior product engineering

Senior engineering for apps, integrations, and product recovery

Radiance helps founders, product teams, and agencies build new products, rescue existing ones, connect critical systems, and keep releases stable.

When to call

High-leverage moments for senior engineering

The strongest fit is not a generic task list. It is a product moment where the right technical decision saves time.

A first release needs shape

Turn rough requirements into a realistic scope, technical foundation, and launch path.

A product is stuck

Find the blocker, reduce the risk, and move the next release forward without a rewrite by default.

Systems need to talk

Connect product flows, operational tools, providers, data, automation, or AI where handoffs are breaking.

The team needs senior hands

Add calm implementation capacity for a roadmap, client project, or overloaded product team.

Process

How we work

A simple delivery loop: understand the product, remove uncertainty, ship in useful steps, then keep it healthy.

01
Orient
Goal, current state, constraints, users, and the business outcome.
02
Inspect
Code, systems, data, integrations, release risk, and architecture choices.
03
Plan
Milestones, assumptions, estimate, and the first valuable increment.
04
Ship
Focused implementation, QA, communication, and release preparation.
05
Improve
Monitor, stabilize, clean up, and extend after real usage creates signal.

Engagement

Choose the right starting point

Start with clarity, ship a focused milestone, or keep the product stable with senior engineering support.

When: Unclear scope
Best start: Discovery sprint
Result: Scope, risks, first milestone

Before estimates, roadmap promises, or a larger build.

When: Need to ship
Best start: Build or rescue
Result: Working increment or fixed blocker

For product apps, APIs, integrations, AI, or release work.

When: Need continuity
Best start: Support partner
Result: Stable releases and senior capacity

For ongoing fixes, monitoring, improvements, or white-label work.

Smallest useful start. Expand only when it helps.

FAQ

Questions that affect scope

Short answers before discovery, audit, MVP delivery, or support.

Short version

We can start small, inspect existing systems, define risk before estimates, and continue after launch.

Ask about your project

What kinds of projects do you take?

Product systems, internal tools, platform/API work, integrations, AI assistants, audits, refactoring, and ongoing product support.

Can you build an MVP from scratch?

Yes. We help define a focused launch scope, design the technical foundation, build the product, connect key integrations, and prepare it for release.

Can you join an existing project?

Yes. We can inspect the codebase, understand the workflow, then help with features, bugs, refactoring, performance, releases, or support.

Do you work with agencies?

Yes. We support agencies through subcontracting and white-label development for product applications, backend, fullstack, AI, and integration work.

How do estimates work?

Final timelines and prices come after technical assessment. We first clarify scope, risks, assumptions, milestones, and delivery constraints.

What is the best way to start?

Send the product state, goal, timeline pressure, and known constraints. We can recommend discovery, audit, or a first milestone.

Contact

Tell us what needs to move.

No full specification needed. A short note about the product, current state, constraints, and target outcome is enough.

Where the message goes

Project requests are routed to [email protected]. If you prefer a direct thread, email the same address with a short project note.

1. Your request is reviewed

We look at the goal, product state, risks, and whether discovery or a first milestone makes sense.

2. We reply with a useful next step

You get a practical response: questions, suggested scope, audit path, or estimate process.

3. Final estimates come after assessment

Timelines and budgets come after understanding the technical work and assumptions.
