PostgreSQL hot standby feedback. How it works.

From time to time, people come to us with a problem, “Our queries cancelled on standby servers, and we enabled hot_standby_feedback, but queries on standby get cancelled. Why?”. Indeed,…

This is an induction phase, during which your databases will undergo a thorough review by our DBA, who will:

Questions related to database and OS configuration
Basic query optimisation
Questions that do not require an in-depth investigation
Post factum analysis of database outages (during working hours)
Autohealthcheck reports review (we notify you of any abnormalities)

Subject to client’s installation specifications and databases access Phase 1 may take longer and require additional fee. This will be pre-agreed with client in advance.

During Audit and Optimisation (Phase 1) Data Egret provides support with up to 3h response during working hours.
During the Ongoing support (Phase 2) we answer any questions via email with up to 24 hours response time during working hours.

If you are interested in shorter response times we suggest our 24/7 PostgreSQL Support services.

Database Access: Data Egret Service Desk Annual Subscription can be provided with or without access to databases, however without database access addressing any issues will require more time making the process less cost-effective.

We are a consulting firm that offers PostgreSQL administration services. We are looking for a seasoned PostgreSQL DBA specialist for a full-time remote position.

Who will you be working with?

Depending on the client’s team structure you will be working with either client’s DBAs, developers, DevOps or technical managers.

What skills will you gain?

In addition to harnessing your technical skills you will grow as a technical support specialist, who is able to listen to our clients, ask questions, review possible solutions with them, and be a reliable partner, who will be a valuable member of the extended client’s team beyond their expectations.

What will your job be like?

You will be the focal point to our clients when it comes to databases – figuring out why things don’t work the way they should, providing guidance and fixes to ensure that our client’s HA projects go like clockwork.

Here are a few examples of your day-to-day technical tasks:

Working with physical/logical replication.
Make changes in schema under load with minimum downtime.
Perform slow query analysis and optimization.

Setting up and configuring Postgres.

What do we expect from you?

You are a seasoned DBA with 2 or more years of experience in administering high availability.
PostgreSQL projects (including replication configuration, performance tuning, monitoring configuration etc.).
Have experience in optimizing complex SQL queries.
Enjoy working independently on vague client briefs (leading an open dialog with client in order to obtain the necessary information regarding client’s problems, identify the issue, offer and discuss with client possible solutions and communicate upon delivery).
You are a confident Linux user and know how to perform basic system administration (Ubuntu/Debian/RedHat).
Have general understanding of database theory.
Have basic knowledge of shell scripting (writing screens-lengthy scripts that will be understandable to other admins and to yourself a few months later).
You can write and especially read complex (and very complex) SQL queries.
You are a keen learner and eager to discover new solutions to old problems.

This is a client facing role and the ability to communicate your actions and be able to reason with client is imperative.

What skills would be a plus?

Familiarity with Patroni.
Familiarity with some DevOps tools such as Ansible/Docker/Kubernetes.
Experience performing recovery from a backup.
C programming skills and experience in analysing with perf/strace/gdb.
Administration experience with cloud platforms.
Interest in giving conference talks and/or writing technical blog posts.
Experience working with PgBouncer.
Experience working with Postgres source code.
You performed or supported through migrations to Postgres from other DBMS.
You know how to work with monitoring solutions (DataDog, Odarix, NewRelic, Zabbix, pgwatch2 or other services/tools), as well as working with PostgreSQL logs gathering and interpreting data.

Why choose Data Egret as your place of work?

You will be a part of one of the leading PostgreSQL DBA teams working in a consultancy that has been named a significant sponsor to PostgreSQL by the Postgres community.
You will be able to brush up your database administration skills on a multitude of databases in different environments and gain experience that would normally take you years to get working in-house within months.

We offer:

A competitive pay based on your experience and annual performance-based bonus scheme.
Full-remote working.
Flexible working hours.
An opportunity to work alongside DBA colleagues, who live and breathe Postgres and contribute to its development.
