DeFi Data / Protocol Integration Engineer | Careers

About the role

Siqure is a technology-driven asset management firm operating at the intersection of traditional finance, structured products, digital assets, and institutional DeFi. We are building the platform infrastructure required to support product entry, capital intake, treasury, wallet and custody workflows, DeFi strategy execution, portfolio monitoring, risk intelligence, reconciliation, and institutional reporting.

The DeFi Data / Protocol Integration Engineer will own the integration and data layer that allows Siqure to understand, monitor, reconcile, and report on DeFi positions across approved protocols, wallets, custody providers, risk providers, and blockchain data sources.

This is a hands-on engineering role for someone who can combine strong backend delivery with DeFi protocol understanding, data modelling, operational judgement, and critical thinking.

Key Responsibilities

Own and build integrations with DeFi protocols, portfolio aggregators, custody providers, risk providers, blockchain data sources, and future settlement-related systems
Design canonical data models for protocol positions, wallet balances, protocol exposures, yield metrics, transaction flows, liquidity conditions, and risk signals
Integrate and normalise data from DeBank, Morpho, Pendle, Fordefi, Hypernative, direct chain reads, protocol APIs, indexers, and future provider sources
Build reliable real-time and scheduled data pipelines for portfolio positions, APR/APY and yield tracking, liquidity monitoring, transaction classification, protocol health, and risk metrics
Own reconciliation logic comparing Siqure internal records against custody provider data, protocol data, aggregator data, direct on-chain state, and reporting outputs
Support DeFi execution workflows by preparing protocol interaction context, transaction payload data, pre-trade checks, withdrawal/claim flows, and post-trade confirmation records
Work with quant, portfolio, treasury, risk, operations, and engineering teams to operationalise approved DeFi strategies safely
Evaluate new DeFi protocols and networks from an integration, data quality, risk, liquidity, operational readiness, and reporting perspective
Create monitoring and alerting for protocol health, wallet movement, data freshness, reconciliation mismatches, exposure changes, and position anomalies
Produce and maintain technical documentation for protocol integrations, data contracts, provider mappings, reconciliation rules, assumptions, failure modes, and recovery procedures
Demonstrate strong engineering ownership by identifying unclear requirements, surfacing risks early, proposing practical designs, and following issues through to production readiness

Required Experience

5+ years of software engineering experience, preferably in financial systems, data infrastructure, Web3, DeFi, digital asset platforms, or backend platform engineering
Strong C#/.NET backend engineering experience, or strong Rust, Go, or Python experience with willingness and ability to work in a C#/.NET platform environment
Hands-on experience integrating with DeFi protocols, blockchain data sources, wallet data, portfolio aggregators, custody providers, risk providers, or similar financial data systems
Practical experience with EVM data: transaction hashes, logs/events, token balances, contract reads, RPC providers, indexers, subgraphs, and web3 libraries such as ethers.js, viem, web3.py, Nethereum, or similar
Understanding of DeFi primitives: lending protocols, AMMs, yield protocols, liquid staking, vaults, collateral, liquidity pools, derivatives, and structured yield products
Ability to interpret APR, APY, implied yield, realised yield, utilisation, liquidity, maturity, exposure, position state, and protocol-specific metrics
Experience building reliable workers, APIs, data pipelines, integration services, reconciliation jobs, monitoring dashboards, and alerting systems
Strong understanding of data quality, idempotency, retries, provider failure handling, source-of-truth rules, auditability, and operational resilience
Strong ownership mindset: able to reason from first principles, challenge incomplete requirements, communicate trade-offs, and make sound engineering decisions under uncertainty
Ability to collaborate effectively with engineers, portfolio managers, quant researchers, risk teams, treasury, operations, and leadership

Preferred Experience

Experience with Morpho, Pendle, Aave, Compound, Curve, Uniswap, GMX, Lido, EigenLayer, or similar protocols
Experience working with DeBank, Fordefi, Hypernative, Fireblocks, Safe, The Graph, Dune, Goldsky, Alchemy, Infura, Tenderly, or similar providers
Experience designing portfolio, position, valuation, exposure, treasury, wallet, or reconciliation models for digital assets
Experience with event-driven architecture, background workers, ClickHouse, PostgreSQL, Kafka, RabbitMQ, Redis, OpenTelemetry, Grafana, Docker, or Kubernetes
Experience in institutional asset management, fintech, treasury, custody, regulated financial environments, or compliance-heavy systems
Ability to read Solidity contracts and understand contract interactions, emitted events, approvals, allowances, and security implications
Familiarity with protocol risk, oracle risk, bridge risk, liquidity risk, liquidation mechanics, MEV, gas economics, and chain-specific operational risks

Engineering Qualities We Value

Quality	What it means at Siqure
Ownership	You do not stop at implementation. You understand the business impact, data consequence, operational risk, and reporting implication.
Critical thinking	You challenge unclear assumptions, investigate mismatches, and avoid blindly trusting provider data.
Systems thinking	You design for workflows, failure modes, reconciliation, auditability, and long-term extensibility.
Pragmatism	You can ship useful MVP slices without locking the platform into short-term provider assumptions.
Communication	You can explain DeFi mechanics, data assumptions, and risks to technical and non-technical stakeholders.

What This Role Is Not

This is not primarily a Solidity smart contract authoring role
This is not a pure quant research role
This is not a dashboard-only data role
This is not a protocol-building role where the main responsibility is creating new DeFi primitives

This is a hands-on DeFi protocol integration, data infrastructure, reconciliation, risk signal, and institutional reporting role.

Success in the First 90 Days

Timeline	Expected outcome
First 30 days	Understand Siqure's Product Entry, Capital Intake, Treasury, Wallet/Custody, Strategy, Portfolio, Risk, and Reporting model. Map current provider and protocol data responsibilities.
First 60 days	Deliver or materially contribute to canonical DeFi position, wallet, yield, and provider data models, including ingestion and reconciliation approach for priority providers.
First 90 days	Implement or materially contribute to a working vertical slice that ingests protocol/provider data, reconciles it against internal records, and supports portfolio, risk, and reporting outputs.
