What a Solidity developer does for you
Solidity is easy to write and hard to write safely. Our Solidity developers start from a specification of roles and invariants, use well-reviewed libraries, keep code small, and test with unit, fuzz, invariant and fork tests. They hand over deployment scripts, admin procedures and a known-issues list so your independent auditors spend time on real risk.
When to hire
- You are preparing contracts for an external audit
- You need to extend or upgrade contracts already in production
- You are building a DeFi, token or tokenization protocol
- You need gas optimisation without trading away safety
Responsibilities
What they will own
- Write specifications, invariants and threat models
- Implement contracts with established libraries
- Build fuzz, invariant and fork test suites
- Resolve static-analysis findings
- Plan upgrades, timelocks and multisig administration

How we assess every Solidity developer
Profiles are shared only after these checks. You then run your own interviews.
- Review of audited or deployed contracts
- Timed security-focused coding exercise
- Invariant and fuzz-testing interview
- Written explanation of a design trade-off
Hiring process
From requirement to first sprint
- 1Share your requirementRoles, seniority, stack, time-zone overlap and what the developers will own.
- 2Review profilesWe shortlist engineers whose experience matches, and share profiles for your review.
- 3InterviewYou interview every candidate. Nobody joins your project without your approval.
- 4Onboard & startAccess, rituals and first-sprint goals are agreed; the developer works in your tools.
- 5Review & scaleRegular check-ins on quality and velocity. Scale the team up or down as the roadmap changes.
Engagement models
Choose how the developers work with you
Individual Specialist
1 engineerA senior specialist embedded in your team to fill a specific skill gap.
Best for: Adding expertise such as smart contracts, AI or platform engineering to an existing team.
Dedicated Pod
2–4 peopleA small, self-organising unit focused on a feature area or workstream.
Best for: Owning a defined area of your product with minimal management overhead.
Dedicated Team
5–10 peopleA full cross-functional team working exclusively on your roadmap.
Best for: Building or evolving a product or platform over the long term.
Extended Team
FlexibleShivacha engineers integrated into your existing teams as additional capacity.
Best for: Accelerating an in-house roadmap without changing team structure.
Product Squad
4–8 peopleProduct, design and engineering together, accountable for product outcomes.
Best for: New products or product lines needing end-to-end ownership.
Managed Engineering
Scoped to outcomesShivacha owns delivery of defined outcomes with service levels and reporting.
Best for: Delegating a product, platform or operational workstream entirely.
Team composition
Teams are shaped to your roadmap, stack and domain, with profiles shared for your review before anyone starts.
Responsibilities
A written responsibilities matrix defines who owns what — priorities, architecture, delivery, quality and operations.
Communication
Teams work in your tools and rituals: stand-ups, planning, demos and retrospectives, with agreed time-zone overlap.
Delivery
Delivery managers track progress and risks, with regular demos and transparent reporting against agreed metrics.
Security
Least-privilege access, company-managed devices, secure credential handling and confidentiality agreements for every engineer.
Scaling
Teams scale up or down with notice periods agreed in the engagement, with knowledge transfer built into every change.
Engagement
Monthly engagements with clear terms, IP assigned to you and regular performance reviews with your leadership.

Frequently asked questions
Do your Solidity developers perform audits?
No. They prepare contracts for audit and review each other's code, but an independent audit firm should audit any contract that will hold meaningful value.
How quickly can developers start?
It depends on the role, seniority and number of people. We share profiles for your review first; initial engineers can often start within a few weeks of agreeing scope. We will not promise a start date before we have checked availability.
Do the developers work in our tools and time zone?
Yes. They work in your repositories, tracker and chat, and we agree a meaningful overlap with your working hours before the engagement starts. We have offices in India, the USA and the UK.
Who owns the code?
You do. All work product and IP are assigned to you under the engagement agreement, and NDAs are signed before any confidential material is shared.
Can we interview the developers?
Yes. You review profiles and can interview every engineer before they join your project.
